Essay On Neuroimaging
With the advancement in technology, neuroimaging has led to the discovery of male brains containing a greater amount of white matter, while female
brains contain more gray matter (Gur et al., 1999). Sun et al. (2015) collected imaging data to track the progress of brain network topology over a
five–year period and compared the results between gender differences. Participants in the study included 43 males ranging from ages 22–53, and 28
females from ages 21–59. Only those having no brain disorders, mental illnesses, substance abuse, or first–degree family members with mental
illnesses were included in the research. Twenty–eight subjects completed the study and received scans over 5 years. The results supported findings

The article suggests women perform more confidently when working in groups composed of predominantly women. When women are the minority in
a collaborative group, they do not typically perform as well. Consequently, men may work well in many types of gender group combinations due to
their increased confidence in performance abilities.
Barriga, Morrison, Liau, and Gibbs (2001) conducted a study to determine if there was a significant difference between genders regarding antisocial
behavior. The researchers recruited 88 males and 105 adolescents, ranging from ages 16–19 from a large Midwestern university. The participants were
given numerous test batteries to determine their internalizing and externalizing aggregate scales. A correlation analysis was then performed to portray
the relationship between behavioral and moral cognitive variables. The study found males are prone to have a higher risk for antisocial behaviors due
to lower mature moral judgement, more self–relevance, and higher self–serving cognitive distortion, possibly playing a role in their cognitive processes.
Kennedy, Kray, and Ku (2017) conducted five separate studies involving social–cognitive frameworks to describe differences in gender negotiating
ethics, and when females employ smaller amounts of unethical negotiating behaviors than men do. The study found women had a stronger moral
identity compared to men, which decreases the temptation to rationalize, plot, and participate in

Should the police be allowed to impose brain scans on suspects, assuming that brain scans can help proving mens rea?
The English criminal justice system is based upon a "range of decisions and procedures from the investigations and questioning of people" which
develop the common sense ideas of free will and responsibility for conduct. Imposing Brain scans on suspects by the police excludes the system from
procedures of investigation and questioning, which is known to be justice. Brain scans can be used for the element of the criminal law of mens rea,
which is required under the criminal justice system to convict one of crime. However the presumption of innocence and a fair trial would be under

This is due to the fact that police officers will have evidence taken from the defendant's brain scans, which produces "70 to 90 per cent of
accuracy". Thus, the defendant would have been proven guilty, before commencing trials. As well as, it is believed here that the use of brain scans
by police and evidence would misdirect the Jury, as Dr Farahany states that jurors often tend to believe that science is the objective truth, therefore
showing that if police officer are given the right to use brain scans on suspects, evidence taken from the scans in court would be regarded more
sufficient than "witness interviews, testimony by the accused under cross examination, and even the person's body language". United States v. John
W. Hinckley Jr. present the above argument due to Jury not finding Hinckley not guilty by the reason brain scan image was central to jury's
decision. Also, due to the Brain scans being "70 to 90 per cent" accurate, this producing a defence for a defendant to argue that the scan in inaccurate,
causing the process of scans to be a waste of time. As previously seen In R v BГ©land the Supreme Court of Canada ruled that the results of a
polygraph examination are not admissible as evidence. As the test had relied upon ones sweat and heart palpitations which delivered inaccurate results.

The Brain That Changes Itself is an informative and an educational book was written by Canadian Psychiatrist, psychoanalyst, writer, and researcher

It is full of comprehensive and engaging style; well reference and scientifically proven, summarizes the current revolution in neuroscience and
neuroplasticity, and closes the gap that the old age or matured brain, which is unchangeable is changeable and malleable (plastic); extending it
functions from one region to the other. Doidge engaging style of writing, scientific proves, and academic tone help to make the book persuasive.
In classical neuroscience, there was the theory that the adult brain was considered fixed and inflexible; every part had a specific purpose and function
and when it is damaged, cannot be replaced or repaired. Today experimental techniques suggest and embrace the recognition that the brain is plastic
and can change itself with exercise and understanding whether you are an infant or an adult. It explains that the brain is constantly seeping out in
various directions and is apparently able to respond to injury with a striking functional reorganization, and sometimes actually thinks itself into a new
structure of body arrangement. Doidge also argues that plasticity can be good or bad based on the way a brain is used. For instance, on the wrong side

The Theory Of The Mind Becomes Of Critical Importance
As neuroscience research progresses, the concept of the mind becomes of critical importance. The mind is usually considered to be a separate,
nonmaterial entity compared to the physical neurons within the brain. However, the field of neuroscience is finding many connections between the
physical nature of the brain and the supposed non–physical aspect of the human mind. In a sense, neuroscience seeks to understand the functioning of
the mind in terms of the physical neuronal firings of the brain. In addition, neuroscience seeks further information concerning the "fixity" and
"plasticity" of the brain. The field of neuropsychology was developed in response to these questions. The field of neuropsychology was born at the
beginning of the 20th century, shortly after the end of World War II. Early neuropsychology was a combination of 20th century neurologist's views and
experimental psychology's new behavioral techniques. The returning veterans from World War II sparked the rapid growth of the field. Many
veterans developed cases of mental illness from their exposure to the horrors of war. Thus, the field of neuropsychology was born in response to a
medical need. The rush in neuropsychology did not slow after World War II, but rather transitioned into the study of cognition. Early neuropsychology
studies of cognition generally investigated the topics of memory and visual perception. For example, neurophysiologists David Hubel and Thorsten

Functional Neuroimaging Analysis
According to Klein (2010) functional neuroimaging technologies, such as positron emission tomography (PET) and functional magnetic resonance
imaging (fMRI), have revolutionized neuroscience, and provided crucial tools that link cognitive psychology and traditional neuroscientific models in
the diagnosis and treatment of brain disorders (Klein, 2010; Sabb & Bilder, 2006). Neuroimaging refers to a collection of techniques that allow scientists
to investigate the functions of the brain through the detection of metabolic changes caused by the increase in neural activity during a task (Klein,
2010). Similarly, Moran and Zaki (2013) state that functional neuroimaging has become a primary tool in the study of human psychology (Moran &

Social Emotional And Executive Function Defects Essay
Through the decades, researchers have tried to solve the mystery of the enigmatic prefrontal cortex. Along with the famous case of Phineas Gage
(Harlow,1848), many studies have attempted to answer the burning question of either or not lesions to the prefrontal cortex lead to an antisocial
behavior. The PFC, which is found in the frontal lobe and has an executive function, helps us have an appropriate response to social situations. Why
is it important to study this matter? Because we are social creatures and knowing how to act in society is one of our basic needs. The studies which
will be presented show that there is an obvious link between dysfunction of the PFC and an antisocial way of acting.
In the developmental neuropsychology literature, it has been proved that social–emotional and executive function defects are associated with early
damage to the PFC. Piaget (1968) claimed that children learn from experience and this is the way in which they obtain adaptive characteristics.
Therefore, studying patients such as children can give a lot of information about the effect of brain maturation and social development.
The study conducted by Eslinger(2004) reveals 10 cases of patients suffering from early prefrontal cortex damage highlighting "one of the most
informative cases available in the literature on human prefrontal lobe damage", the case of Acherly and Benton(1948). JP, the person who was being

Neuromarketing
Within the skull lies the most complex organ known to mankind –– the human brain. With a mass of only 6 kilograms, the brain contains over 100
billion living cells and 1 million kilometers of interconnecting fibers; but, exactly how does it function? Marketing and sales managers would love to
know why consumers are attracted to certain advertising, packaging and brands. Martin Lindstrom, author of Buyology: Truth and Lies About Why
We Buy, explains the marketing challenge, "When we walk down an aisle in a grocery store, our purchasing decisions are made in less than four
seconds...there is no way we can think about that in a complete way. Those decisions take place in the subconscious part of the brain" (2008).

It likes beginnings and endings and tends to drop the information in the middle. Therefore, placing the most important context in the beginning and
restating it at the end is a must to grab the consumer's old brain's attention. The fifth stimulus is visual. The old brain is very visual; this may be
because the optic nerve is directly connected to it. "About 70% of the body's sense receptors are in our eyes. To a large degree, we understand our
world mainly by looking at it...we have evolved to put our visual senses at the top of our sensory hierarchies, and therefore, visual components tend to
trump all others" (Pradeep, 2010). The old brain reacts to an object before your new brain physically recognizes the object. The last stimulus is emotion.
When consumers experience strong emotions like happiness, sadness, anger or joy, a flood of emotions rushes into their brain and impact the synaptic
connections between the neurons making them faster and stronger. As a result, consumers will remember events better when they have experienced
them with strong emotions.
Analyzing Neuroimaging Techniques In order to measure the brain effectively, neuromarketers use the latest technology that assess the brain's activity

Different Study Designs When Investigating Cognitive And...
1.There are various advantages and disadvantages of different study designs when investigating cognitive and neural ageing using neuroimaging.
Several theories of cognitive ageing have been based on cross–sectional designs where there is a common understanding that multifarious age studies
can lead to a better understanding of the propinquity among age–related processes (Hofer, Sliwinski and Flaherty, 2002). This method is proven to be
cost effective, renders quick results, and is the best way to determine prevalence and identifying associations within a group (Mann, 2003). However,
Salthouse (2009) pointed out that comparisons of people of different ages at a particular time does not necessarily express changes that will arise
within an individual as he ages. He explained that confounding factors, such as maturation, which refers to the person growing older and undergoing
different experiences and influences, must be determined in each participant to know how each one has been effected. Raz and Kennedy (2009) also
identified in a review that cross–sectional studies have often only focused on specific parts of the brain in imaging studies, such as the prefrontal cortex,
but many longitudinal studies present larger age–related structural changes in the inferior parietal cortex, the hippocampus, and the cerebellum.
Compared to cross–sectional studies, research on ageing have argued that longitudinal is the most practical way to obtain reliable data, stating that,

Brain Imaging Techniques Used Today

Since the beginning of time people have been trying to understand what is going on inside our heads. With the development and continuous
advancement of brain imaging techniques it has become possible to do just that. It is now possible to produce both structural and functional images of
the brain. While brain imaging techniques have advanced significantly throughout history and proven extremely useful, they still have their limitations.
The purpose of this paper is to give a brief history of brain imaging developments, explain the major brain imaging techniques being used today, and
provide information about what each scan can and can't tell us about the human mind and brain.
A brief history of brain imaging as described by Raichle (2009) begins with the introduction of computerized tomography (CT) in the early 1970s and
development of magnetic resonance imaging (MRI) shortly thereafter, which prompted the invent and use of positron emission tomography (PET), and
then functional magnetic resonance imaging (fMRI) which came in the 1990s (p.119). Since then other forms of brain scanning technology have
appeared such as the Magnetoencephalography (MEG) scan, and other variations of PET and MRI such as diffusion tensor imaging (DTI). The
appearance of these types of brain imaging techniques has provided great insight into the structure and function of the human mind.

Brain Reflection
The Literate Brain seminar is part of the online lecture series called the Evolving Brain. The lecture began with a short video explaining clarity.
Clarity is a way of looking at the brain in which the brain becomes transparent and specific markers can be used to highlight different features. This is
done through the use of a mesh designed to keep the parts of the brain in place and then the fats and lipid bilayer are removed to make the brain
transparent. This allows researchers to more clearly study the individual connections and activated neurons in the brain. Dr. PГ©lagie Beason gave this
lecture and is the head of the Speech, Language, and Hearing Sciences department at the University of Arizona.
Written language has a history of 6,000 years and various across many systems such as symbolic and alphabetic representations. Early language
development is a process of association. Toddlers and children associate various sensory inputs with meaning and begin to learn a systematic code of
signs, sounds, and symbols that become language. Toddlers learn much about spoken language and then in early childhood, children begin to map
spoken words to written words. Literacy development in children begins with visual form recognition and is followed by concept development, spoken
language development, and written language development.

Analysis Of Cognitive Neuroscientists

tomography (PET), functional magnetic resonance imaging (FMRI), electroencephalograph (EEG), magnetoencephalography (MEG) and transcranial
magnetic stimulation (TMS) are all commonly used techniques. Neuroscientists want to use these techniques to construct theoretical models that
represent and explain brain organisation and function (Eysenck & Keane, 2015) in order to match patterns of brain activation with psychological
processes. The spatial (identifying where certain activity happens) and temporal (when the activity happens) resolutions of these neuroimaging

One neuroimaging technique that is used by cognitive neuroscientists that does not use radiation is fMRI. In recent years, there has been a dramatic
shift from PET to the use of fMRI in cognitive studies and no radiation in fMRI is a profound reason for this (Talavage et al., 2014).
Functional MRI (fMRI) looks at the blood oxygen level–dependent contrast (BOLD). It does this by using an MRI scanner where the strong magnetic
field causes protons in the brain to align. A short pulse of radio–frequency will then cause the protons to spin and go back into their original places
which results in the protons losing some energy. When looking at an MRI scan the brightest parts of the brain are the parts where the protons are
giving off most energy. The problem with just an MRI scan is that they only tell researchers about the structure of the brain and not the function. This
is where fMRI becomes extremely useful as they can tell researchers more about the function of the brain. The spatial resolution of an fMRI is
extremely good as it is about 1mm and the temporal resolution is about 2–3 seconds which although could be better, is still a huge improvement on
PET. Since fMRI is not invasive, is widely available and has no exposure to radiation it has become the prominent brain imaging technique used by

Essentially, Alzheimer's causes the computer of thebrain to go down, and the whole of life becomes gradually disarrayed (Gray–Davidson, 1996).
The American Psychiatric Association's definition of Alzheimer's disease contained in the diagnostic manual DSM–IV, is as follows:
The essential feature of the presence of Dementia of insidious onset and gradual progressive course for which all other specific causes have been
excluded by the history, physical examination, and laboratory tests.
The Dementia involves a multifaceted loss of intellectual abilities, such as memory, judgement, abstract thought, and other higher cortical functions,
and changes in personality and behavior (Gray–Davidson, 1996). Alzheimer's is a disease of the brain that causes a steady decline in memory. This
results in dementia, loss of intellectual functions such as thinking, remembering, and reasoning, severe enough to interfere with everyday life
(Gwyther, 2000). As with all dementia's, the rate of progression in Alzheimer's patients varies from case to case. From the onset of symptoms, the
life span of an Alzheimer's victim can range anywhere from 3 to 20 or more years. The disease eventually leaves its victims unable to care for
themselves. While a definitive diagnosis of Alzheimer's disease is possible only through the examination of brain tissue, which is usually done at

The Self Reference Effect On Mother
The extensibility of the self–reference effect to mother
Organism used the sense of self to distinguish itself from the immediate external environment (Neisser, 1988). The idea of 'extended self' suggested that
the self was not limited to the body but also incorporate with self–relevant information (Kim & Johnson 2012). The self–object associations was
developed as far back as early childhood, which showed that ownership was important in cognition (Cunningham, Turk, Macdonald, & Macrae, 2008).
Three research have investigated the association between ownership and cognition. In the study done by Cunningham et al. (2008), participants took
part in a shopping experiment. They were required to move the stimulus items into a basket owned by self or a basket owned by another participant.
The memory for items in both baskets was assessed. They found that participants were significantly recognized more of the objects that moved to the
self–owned basket than to the other–owned basket. The pattern of the improvement in recognition memory was similar to the self–reference effect. The
self–reference effect suggested that information encoded with reference to 'self' enjoyed a memory advantage compared with the information related to
another person because of the enrichment in the representations of the self–relevant objects, and hence the recognition and the memory was improved
(Cunningham et al., 2008).

Sorry, But Your Soul Just Died
The article, "Sorry, but Your Soul Just Died" was an enjoyable read. Tom Wolfe article was quite amusing, and filled with details. Yet, Wolfe was able
to connect and draw out the soul, moral code, and justice within the "neuroscience" discipline. It encapsulated the aggressive materialism of some
new–age scientists. Furthermore, to these self–assured scientific investigators–the concept that the spirit may occur separately from the body is just
absurd. Alternatively, everything is on the "threshold of a unified theory," and a human's "temperament," "role preferences," "emotional responses,"
"levels of aggression," and "moral choices" are genetically determined. And some established theories about "the mind," "the self," "the soul," and "free
will" are nothing but an illusion. In other words, humans' beings are "wired" this way, and religion was probably a mishap. The article was difficult to
follow at times, however, I think Wolfe anticipated the "neuroscience revolution" would start a public debate of whether god actually existed (I guess
Wolfe understood these central claims carried in thinking like this).

defined as the temporal dependency between spatially remote neurophysiological events (Aertsen et al., 1989; Friston et al., 1993). Different brain
regions form a complex network wherein information is shared and processed continuously within structural and functional brain areas. This helps us in

The blood entering the area is oxygen enriched (oxygenated hemoglobin) and results in a decrease of deoxy–hemoglobin. Now, a BOLD contrast can
be defined as the signal generated by suppression of de–oxy blood over oxy–blood. The low frequency oscillations around 0.01 Hz to 0.1 Hz are
critical in understanding resting–state fMRI time–series (Biswal et al., 1995; Biswal et al., 1997; Cordes et al., 2001; Lowe et al., 2000; Lowe et al.,
1996). A resting–state pattern is observed in the areas where there is a high possibility of overlap in function and neuroanatomy. For instance, motor,
visual and auditory network . This helps us to infer that these regions form a functional network during rest. Now, it is important to understand
processing of resting–state fMRI data. The methods through which a rs–fMRI can be obtained are seed based connectivity, principal component
analysis, independent component analysis, singular value decomposition, clustering. A rs–FMRI analysis can be performed either by model–dependent
method or Model free method. A model dependent method is a simple technique in which brain areas are matched with the time–series signal against all
other areas. This results in generating a functional connectivity map (fcMap) for the selected area. A seed can be selected from a task dependent

could actually modify its structural and functional organisation post childhood in response to environmental stimuli saying "Every man can, if he so

the staticity of cognitive function. It was in the 1970's and 80's that controversial animal tests on monkeys infamously known as the 'Silver Spring
Monkeys', confirmed the notion that the brain, or more specifically the central nervous system, was able to change its structure and function, creating
new, more advantageous neural pathways for processing without the help of medication or surgery but as a response to environmental stimuli. The

Monkeys', confirmed the notion that the brain, or more specifically the central nervous system, was able to change its structure and function, creating
new, more advantageous neural pathways for processing without the help of medication or surgery but as a response to environmental stimuli. The
effect has been explained by the Hebbian theory, in Donald Hebbs 'The Organisation of behaviour ', published in 1949, a theory in neuroscience that
proposes an explanation for the adaptation of neurone in the brain during the learning process. The theory attempts to explain associative or Hebbian
learning, in which simultaneous activation of cells leads to pronounced increases in synaptic strength between those cells, and

Essay On Neuroimaging

  • 1. Essay On Neuroimaging With the advancement in technology, neuroimaging has led to the discovery of male brains containing a greater amount of white matter, while female brains contain more gray matter (Gur et al., 1999). Sun et al. (2015) collected imaging data to track the progress of brain network topology over a five–year period and compared the results between gender differences. Participants in the study included 43 males ranging from ages 22–53, and 28 females from ages 21–59. Only those having no brain disorders, mental illnesses, substance abuse, or first–degree family members with mental illnesses were included in the research. Twenty–eight subjects completed the study and received scans over 5 years. The results supported findings from previous ... Show more content on Helpwriting.net ... The article suggests women perform more confidently when working in groups composed of predominantly women. When women are the minority in a collaborative group, they do not typically perform as well. Consequently, men may work well in many types of gender group combinations due to their increased confidence in performance abilities. Barriga, Morrison, Liau, and Gibbs (2001) conducted a study to determine if there was a significant difference between genders regarding antisocial behavior. The researchers recruited 88 males and 105 adolescents, ranging from ages 16–19 from a large Midwestern university. The participants were given numerous test batteries to determine their internalizing and externalizing aggregate scales. A correlation analysis was then performed to portray the relationship between behavioral and moral cognitive variables. The study found males are prone to have a higher risk for antisocial behaviors due to lower mature moral judgement, more self–relevance, and higher self–serving cognitive distortion, possibly playing a role in their cognitive processes. Kennedy, Kray, and Ku (2017) conducted five separate studies involving social–cognitive frameworks to describe differences in gender negotiating ethics, and when females employ smaller amounts of unethical negotiating behaviors than men do. The study found women had a stronger moral identity compared to men, which decreases the temptation to rationalize, plot, and participate in ... Get more on HelpWriting.net ...
  • 2. Should the Police Be Allowed to Impose Brain Scans on... Should the police be allowed to impose brain scans on suspects, assuming that brain scans can help proving mens rea? The English criminal justice system is based upon a "range of decisions and procedures from the investigations and questioning of people" which develop the common sense ideas of free will and responsibility for conduct. Imposing Brain scans on suspects by the police excludes the system from procedures of investigation and questioning, which is known to be justice. Brain scans can be used for the element of the criminal law of mens rea, which is required under the criminal justice system to convict one of crime. However the presumption of innocence and a fair trial would be under threat as one would have been proven guilty ... Show more content on Helpwriting.net ... This is due to the fact that police officers will have evidence taken from the defendant's brain scans, which produces "70 to 90 per cent of accuracy". Thus, the defendant would have been proven guilty, before commencing trials. As well as, it is believed here that the use of brain scans by police and evidence would misdirect the Jury, as Dr Farahany states that jurors often tend to believe that science is the objective truth, therefore showing that if police officer are given the right to use brain scans on suspects, evidence taken from the scans in court would be regarded more sufficient than "witness interviews, testimony by the accused under cross examination, and even the person's body language". United States v. John W. Hinckley Jr. present the above argument due to Jury not finding Hinckley not guilty by the reason brain scan image was central to jury's decision. Also, due to the Brain scans being "70 to 90 per cent" accurate, this producing a defence for a defendant to argue that the scan in inaccurate, causing the process of scans to be a waste of time. As previously seen In R v BГ©land the Supreme Court of Canada ruled that the results of a polygraph examination are not admissible as evidence. As the test had relied upon ones sweat and heart palpitations which delivered inaccurate results. This has also been seen to be the reason why polygraph examinations were excluded as evidence in the English Criminal justice system. Therefore ... Get more on HelpWriting.net ...
  • 3. The Brain That Changes Is An Informative And An... The Brain That Changes Itself is an informative and an educational book was written by Canadian Psychiatrist, psychoanalyst, writer, and researcher Norman Doidge, who delivers a dramatic change message about the plasticity of the brain; how the brain changes itself. "The Brain That Changes Itself" is a chain of excellent case studies of individuals who have undergone a brain deficit of some kind and examines different types of brain deficits from simple sensory; auditory and visual to complex deficits; missing brain regions. The book recounts neuroscientific advances on how neuroplasticity does not limit the individual to predefined neural limitations and that our way of thinking, as well as the activities that we perform every day, ... Show more content on Helpwriting.net ... It is full of comprehensive and engaging style; well reference and scientifically proven, summarizes the current revolution in neuroscience and neuroplasticity, and closes the gap that the old age or matured brain, which is unchangeable is changeable and malleable (plastic); extending it functions from one region to the other. Doidge engaging style of writing, scientific proves, and academic tone help to make the book persuasive. In classical neuroscience, there was the theory that the adult brain was considered fixed and inflexible; every part had a specific purpose and function and when it is damaged, cannot be replaced or repaired. Today experimental techniques suggest and embrace the recognition that the brain is plastic and can change itself with exercise and understanding whether you are an infant or an adult. It explains that the brain is constantly seeping out in various directions and is apparently able to respond to injury with a striking functional reorganization, and sometimes actually thinks itself into a new structure of body arrangement. Doidge also argues that plasticity can be good or bad based on the way a brain is used. For instance, on the wrong side individuals who watches pornography have deleterious part of their brain that makes them addictive to watching porn and ... Get more on HelpWriting.net ...
  • 4. The Theory Of The Mind Becomes Of Critical Importance As neuroscience research progresses, the concept of the mind becomes of critical importance. The mind is usually considered to be a separate, nonmaterial entity compared to the physical neurons within the brain. However, the field of neuroscience is finding many connections between the physical nature of the brain and the supposed non–physical aspect of the human mind. In a sense, neuroscience seeks to understand the functioning of the mind in terms of the physical neuronal firings of the brain. In addition, neuroscience seeks further information concerning the "fixity" and "plasticity" of the brain. The field of neuropsychology was developed in response to these questions. The field of neuropsychology was born at the beginning of the 20th century, shortly after the end of World War II. Early neuropsychology was a combination of 20th century neurologist's views and experimental psychology's new behavioral techniques. The returning veterans from World War II sparked the rapid growth of the field. Many veterans developed cases of mental illness from their exposure to the horrors of war. Thus, the field of neuropsychology was born in response to a medical need. The rush in neuropsychology did not slow after World War II, but rather transitioned into the study of cognition. Early neuropsychology studies of cognition generally investigated the topics of memory and visual perception. For example, neurophysiologists David Hubel and Thorsten Wiesel studied the vision of cats via ... Get more on HelpWriting.net ...
  • 5. Functional Neuroimaging Analysis According to Klein (2010) functional neuroimaging technologies, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), have revolutionized neuroscience, and provided crucial tools that link cognitive psychology and traditional neuroscientific models in the diagnosis and treatment of brain disorders (Klein, 2010; Sabb & Bilder, 2006). Neuroimaging refers to a collection of techniques that allow scientists to investigate the functions of the brain through the detection of metabolic changes caused by the increase in neural activity during a task (Klein, 2010). Similarly, Moran and Zaki (2013) state that functional neuroimaging has become a primary tool in the study of human psychology (Moran & Zaki, 2013). ... Get more on HelpWriting.net ...
  • 6. Social Emotional And Executive Function Defects Essay Through the decades, researchers have tried to solve the mystery of the enigmatic prefrontal cortex. Along with the famous case of Phineas Gage (Harlow,1848), many studies have attempted to answer the burning question of either or not lesions to the prefrontal cortex lead to an antisocial behavior. The PFC, which is found in the frontal lobe and has an executive function, helps us have an appropriate response to social situations. Why is it important to study this matter? Because we are social creatures and knowing how to act in society is one of our basic needs. The studies which will be presented show that there is an obvious link between dysfunction of the PFC and an antisocial way of acting. In the developmental neuropsychology literature, it has been proved that social–emotional and executive function defects are associated with early damage to the PFC. Piaget (1968) claimed that children learn from experience and this is the way in which they obtain adaptive characteristics. Therefore, studying patients such as children can give a lot of information about the effect of brain maturation and social development. The study conducted by Eslinger(2004) reveals 10 cases of patients suffering from early prefrontal cortex damage highlighting "one of the most informative cases available in the literature on human prefrontal lobe damage", the case of Acherly and Benton(1948).

  • 7. Neuromarketing Within the skull lies the most complex organ known to mankind –– the human brain. With a mass of only 6 kilograms, the brain contains over 100 billion living cells and 1 million kilometers of interconnecting fibers; but, exactly how does it function? Marketing and sales managers would love to know why consumers are attracted to certain advertising, packaging and brands. Martin Lindstrom, author of Buyology: Truth and Lies About Why We Buy, explains the marketing challenge, "When we walk down an aisle in a grocery store, our purchasing decisions are made in less than four seconds...there is no way we can think about that in a complete way. Those decisions take place in the subconscious part of the brain" (2008). The drive behind ... Show more content on Helpwriting.net ... It likes beginnings and endings and tends to drop the information in the middle. Therefore, placing the most important context in the beginning and restating it at the end is a must to grab the consumer's old brain's attention. The fifth stimulus is visual. The old brain is very visual; this may be because the optic nerve is directly connected to it. "About 70% of the body's sense receptors are in our eyes. To a large degree, we understand our world mainly by looking at it...we have evolved to put our visual senses at the top of our sensory hierarchies, and therefore, visual components tend to trump all others" (Pradeep, 2010). The old brain reacts to an object before your new brain physically recognizes the object. The last stimulus is emotion. When consumers experience strong emotions like happiness, sadness, anger or joy, a flood of emotions rushes into their brain and impact the synaptic connections between the neurons making them faster and stronger. As a result, consumers will remember events better when they have experienced them with strong emotions. Analyzing Neuroimaging Techniques In order to measure the brain effectively, neuromarketers use the latest technology that assess the brain's activity most accurately. Although there are apparently many techniques that scientists propose, only a few have stood the test of time and are being used most widely. The three techniques are Electroencephalogram (EEG), Functional ... Get more on HelpWriting.net ...
  • 8. Fear Is Something That Almost People Have Experienced At Fear is something that almost people have experienced at least once in their lives. It is also considered as a natural rule that everyone can barely resist or avoid. In many people's opinions, fear seems to be useless, and becomes an obstacle which prevents people from being successful. Consequently, we are repeatedly encouraged to conquer and overcome it. However,fear is not always negative, it sometimes brings us benefits. What if everybody could defeat their fears, how the world would be? Would it become a better place? Fear is the feeling of anxiety about something terrible may happen to us. Based on Roger Hart's experiments on children in 1970s and children of the new generation, fear is not innate but formed by the environment and ... Show more content on Helpwriting.net ... By the time, we see many cases of kidnapping, murder, and accident as the proofs for what we have learned about the unsafe society. We cannot ignore it because we are aware that similar things may happen to us. We are not born to be afraid; however, media, education, and real–life experiences help build a taller castle of fear in our mind which is really hard to collapse. I used to think that fear is so troublesome. If there was no fear on earth, life would be easier. Everything has changed after getting to know a case of fearless woman, SM. Fearlessness is also has negative and positive side. It is a very rare disease called Urbach–Wiethe disease that only four hundred cases have been identified. Everyone who has this disease usually has three symptoms: externally hoarse voice, small bumps around eyes, and little stones in certain parts of the brain, especially amygdala. Scientists had done many tests to check SM's ability to fear. She expressed no experience of fear to snakes and even with a man who held a knife to her throat. This is very dangerous because she cannot conceive of the threat might happen to her so that she hardly can avoid it. Fear is crucial for survival. However, because SM has no fear, she does not think that threats are bad for her. This makes SM happier and more satisfied with her life. Everything seems to be benign with her, and she can really enjoy her life. Fear is the ... Get more on HelpWriting.net ...
  • 9. Different Study Designs When Investigating Cognitive And... 1.There are various advantages and disadvantages of different study designs when investigating cognitive and neural ageing using neuroimaging. Several theories of cognitive ageing have been based on cross–sectional designs where there is a common understanding that multifarious age studies can lead to a better understanding of the propinquity among age–related processes (Hofer, Sliwinski and Flaherty, 2002). This method is proven to be cost effective, renders quick results, and is the best way to determine prevalence and identifying associations within a group (Mann, 2003). However, Salthouse (2009) pointed out that comparisons of people of different ages at a particular time does not necessarily express changes that will arise within an individual as he ages. He explained that confounding factors, such as maturation, which refers to the person growing older and undergoing different experiences and influences, must be determined in each participant to know how each one has been effected. Raz and Kennedy (2009) also identified in a review that cross–sectional studies have often only focused on specific parts of the brain in imaging studies, such as the prefrontal cortex, but many longitudinal studies present larger age–related structural changes in the inferior parietal cortex, the hippocampus, and the cerebellum. Compared to cross–sectional studies, research on ageing have argued that longitudinal is the most practical way to obtain reliable data, stating that, ... Get more on HelpWriting.net ...
  • 10. Brain Imaging Techniques Used Today Brain Imaging Techniques Duane Perrin Eastern Oregon University 11/11/2016 Since the beginning of time people have been trying to understand what is going on inside our heads. With the development and continuous advancement of brain imaging techniques it has become possible to do just that. It is now possible to produce both structural and functional images of the brain. While brain imaging techniques have advanced significantly throughout history and proven extremely useful, they still have their limitations. The purpose of this paper is to give a brief history of brain imaging developments, explain the major brain imaging techniques being used today, and provide information about what each scan can and can't tell us about the human mind and brain. A brief history of brain imaging as described by Raichle (2009) begins with the introduction of computerized tomography (CT) in the early 1970s and development of magnetic resonance imaging (MRI) shortly thereafter, which prompted the invent and use of positron emission tomography (PET), and then functional magnetic resonance imaging (fMRI) which came in the 1990s (p.119). Since then other forms of brain scanning technology have appeared such as the Magnetoencephalography (MEG) scan, and other variations of PET and MRI such as diffusion tensor imaging (DTI). The appearance of these types of brain imaging techniques has provided great insight into the structure and function of the human mind. First, it is important ... Get more on HelpWriting.net ...
  • 11. Brain Reflection The Literate Brain seminar is part of the online lecture series called the Evolving Brain. The lecture began with a short video explaining clarity. Clarity is a way of looking at the brain in which the brain becomes transparent and specific markers can be used to highlight different features. This is done through the use of a mesh designed to keep the parts of the brain in place and then the fats and lipid bilayer are removed to make the brain transparent. This allows researchers to more clearly study the individual connections and activated neurons in the brain. Dr. PГ©lagie Beason gave this lecture and is the head of the Speech, Language, and Hearing Sciences department at the University of Arizona. Written language has a history of 6,000 years and various across many systems such as symbolic and alphabetic representations. Early language development is a process of association. Toddlers and children associate various sensory inputs with meaning and begin to learn a systematic code of signs, sounds, and symbols that become language. Toddlers learn much about spoken language and then in early childhood, children begin to map spoken words to written words. Literacy development in children begins with visual form recognition and is followed by concept development, spoken language development, and written language development. Adult literacy complements handwriting skills with typing and texting skills. In adult literacy, adult vocabulary grows and new word learning ... Get more on HelpWriting.net ...
  • 12. Analysis Of Cognitive Neuroscientists Cognitive neuroscientists use several brain imaging methods that look at the structure or function of the brain to study cognition. Position emission tomography (PET), functional magnetic resonance imaging (FMRI), electroencephalograph (EEG), magnetoencephalography (MEG) and transcranial magnetic stimulation (TMS) are all commonly used techniques. Neuroscientists want to use these techniques to construct theoretical models that represent and explain brain organisation and function (Eysenck & Keane, 2015) in order to match patterns of brain activation with psychological processes. The spatial (identifying where certain activity happens) and temporal (when the activity happens) resolutions of these neuroimaging techniques have an important ... Show more content on Helpwriting.net ... One neuroimaging technique that is used by cognitive neuroscientists that does not use radiation is fMRI. In recent years, there has been a dramatic shift from PET to the use of fMRI in cognitive studies and no radiation in fMRI is a profound reason for this (Talavage et al., 2014). Functional MRI (fMRI) looks at the blood oxygen level–dependent contrast (BOLD). It does this by using an MRI scanner where the strong magnetic field causes protons in the brain to align. A short pulse of radio–frequency will then cause the protons to spin and go back into their original places which results in the protons losing some energy. When looking at an MRI scan the brightest parts of the brain are the parts where the protons are giving off most energy. The problem with just an MRI scan is that they only tell researchers about the structure of the brain and not the function. This is where fMRI becomes extremely useful as they can tell researchers more about the function of the brain. The spatial resolution of an fMRI is extremely good as it is about 1mm and the temporal resolution is about 2–3 seconds which although could be better, is still a huge improvement on PET. Since fMRI is not invasive, is widely available and has no exposure to radiation it has become the prominent brain imaging technique used by cognitive neuroscientists today (Xue, Chen, Lu, & ...

The American Psychiatric Association's definition of Alzheimer's disease contained in the diagnostic manual DSM–IV, is as follows: The essential feature of the presence of Dementia of insidious onset and gradual progressive course for which all other specific causes have been excluded by the history, physical examination, and laboratory tests. The Dementia involves a multifaceted loss of intellectual abilities, such as memory, judgement, abstract thought, and other higher cortical functions, and changes in personality and behavior (Gray–Davidson, 1996). Alzheimer's is a disease of the brain that causes a steady decline in memory. This results in dementia, loss of intellectual functions such as thinking, remembering, and reasoning, severe enough to interfere with everyday life (Gwyther, 2000). As with all dementia's, the rate of progression in Alzheimer's patients varies from case to case. From the onset of symptoms, the life span of an Alzheimer's victim can range anywhere from 3 to 20 or more years. The disease eventually leaves its victims unable to care for themselves. While a definitive diagnosis of Alzheimer's disease is possible only through the examination of brain tissue, which is usually done at autopsy, it is important for a person suffering from ...

  • 14. The Self Reference Effect On Mother The extensibility of the self–reference effect to mother Organism used the sense of self to distinguish itself from the immediate external environment (Neisser, 1988). The idea of 'extended self' suggested that the self was not limited to the body but also incorporate with self–relevant information (Kim & Johnson 2012). The self–object associations was developed as far back as early childhood, which showed that ownership was important in cognition (Cunningham, Turk, Macdonald, & Macrae, 2008). Three research have investigated the association between ownership and cognition. In the study done by Cunningham et al. (2008), participants took part in a shopping experiment. They were required to move the stimulus items into a basket owned by self or a basket owned by another participant. The memory for items in both baskets was assessed. They found that participants were significantly recognized more of the objects that moved to the self–owned basket than to the other–owned basket. The pattern of the improvement in recognition memory was similar to the self–reference effect. The self–reference effect suggested that information encoded with reference to 'self' enjoyed a memory advantage compared with the information related to another person because of the enrichment in the representations of the self–relevant objects, and hence the recognition and the memory was improved (Cunningham et al., 2008). In the study done by Kim and Johnson (2012), participants participated in the ... Get more on HelpWriting.net ...

Follow up interviews will be conducted with the opiate user group once a month for a period of six months after the study to determine their levels of drug use. These interviews will be helpful in understanding repeated use and degree of addiction. Proposed Statistics This quantitative quasi–experimental study will employ a single–factor ex–post facto design. Statistical Parametric Mapping (SPM) is a statistic technique that will be used to examine the differences in brain activity recorded functional neuroimging using the neuroimaging techniques (i.e., PET and MRI). The software created by the Wellcome Department of Imaging Neuroscience will be used to conduct this analysis (Daglish et al., 2008). Ethical Considerations There are several ethical issues regarding research on drug addiction. Goodwin and Goodwin (2013) suggest to ensure a study does not have any ethical issues it must be reviewed by the Institute Review Board (IRB). To gain IRB approval the rationale for this study, the procedures, possible risks to the participants and how these risks will be avoided as well as the consent form and materials to be used must be submitted.

  • 17. Summary : ' Sorry, But Your Soul Just Died ' Ricky Vong 10/18/15 PSY 3711 Sorry, But Your Soul Just Died The article, "Sorry, but Your Soul Just Died" was an enjoyable read. Tom Wolfe article was quite amusing, and filled with details. Yet, Wolfe was able to connect and draw out the soul, moral code, and justice within the "neuroscience" discipline. It encapsulated the aggressive materialism of some new–age scientists. Furthermore, to these self–assured scientific investigators–the concept that the spirit may occur separately from the body is just absurd. Alternatively, everything is on the "threshold of a unified theory," and a human's "temperament," "role preferences," "emotional responses," "levels of aggression," and "moral choices" are genetically determined. And some established theories about "the mind," "the self," "the soul," and "free will" are nothing but an illusion. In other words, humans' beings are "wired" this way, and religion was probably a mishap. The article was difficult to follow at times, however, I think Wolfe anticipated the "neuroscience revolution" would start a public debate of whether god actually existed (I guess Wolfe understood these central claims carried in thinking like this). The idea that our genetic code controls most aspects of our lives is arguable. Nowadays, scientists (cell biologists, neuroscientists, etc.) are uncovering concrete evidence that are genetic code is only one of the many complex system of the human body that sways our lives.

  • 18. Functional Connectivity And Its Effect On Neuroimaging A human brain comprises of spatially dispersed, but functionally connected areas that shares information with each other. Functional connectivity is defined as the temporal dependency between spatially remote neurophysiological events (Aertsen et al., 1989; Friston et al., 1993). Different brain regions form a complex network wherein information is shared and processed continuously within structural and functional brain areas. This helps us in determining relation of functional connectivity to a human behavior and would eventually lead to understanding of neurodegenerative diseases. The article focuses on the new imaging and analysis technique and their effect on neuroimaging. Additionally, it also discuss about resting state importance ...

Now, a BOLD contrast can be defined as the signal generated by suppression of de–oxy blood over oxy–blood. The low frequency oscillations around 0.01 Hz to 0.1 Hz are critical in understanding resting–state fMRI time–series (Biswal et al., 1995; Biswal et al., 1997; Cordes et al., 2001; Lowe et al., 2000; Lowe et al., 1996). A resting–state pattern is observed in the areas where there is a high possibility of overlap in function and neuroanatomy. For instance, motor, visual and auditory network . This helps us to infer that these regions form a functional network during rest. Now, it is important to understand processing of resting–state fMRI data. The methods through which a rs–fMRI can be obtained are seed based connectivity, principal component analysis, independent component analysis, singular value decomposition, clustering. A rs–FMRI analysis can be performed either by model–dependent method or Model free method. A model dependent method is a simple technique in which brain areas are matched with the time–series signal against all other areas. This results in generating a functional connectivity map (fcMap) for the selected area. A seed can be selected from a task dependent activation map acquired, pointing a specific area of interest. A disadvantage of this technique is the limited functional connectivity of that area in comparison to ... Get more on HelpWriting.net ...

  • 20. A Short Period Of Critical Development roplasticity? Abstract Introduction Traditionally neuroscientists believed that when you were born, after a short period of critical development just after birth, brain plasticity was fixed. Over 100 years ago Santiago Ramon y Cajal, the father of modern neuroscience, was the first to famously suggest that the brain could actually modify its structural and functional organisation post childhood in response to environmental stimuli saying "Every man can, if he so desires, become the sculptor of his own brain". However lacking in sufficient evidence, until recently the majority of neuroscientists have believed in the staticity of cognitive function. It was in the 1970's and 80's that controversial animal tests on monkeys infamously known as the 'Silver Spring Monkeys', confirmed the notion that the brain, or more specifically the central nervous system, was able to change its structure and function, creating new, more advantageous neural pathways for processing without the help of medication or surgery but as a response to environmental stimuli. The effect has been explained by the Hebbian theory, in Donald Hebbs 'The Organisation of behaviour ', published in 1949, a theory in neuroscience that proposes an explanation for the adaptation of neurone in the brain during the learning process. The theory attempts to explain associative or Hebbian learning, in which simultaneous activation of cells leads to pronounced increases in synaptic strength between those cells, and ...
