Insomnia Essay
Neuroimaging has made it possible to assess abnormal metabolic functions responsible for insomnia. fMRI assists in targeting areas of the brain
experiencing increased blood flow and neuronal activity. Studies that have analyzed the effects of insomnia using magnetic imaging techniques have
concluded that there are characteristic deviations in brain structure and interconnectivity with regard to insomnia. In a recent review, ample evidence
concluded that positive interconnectivity was present in regions of the brain responsible for "...wakefulness, emotion, worry/rumination, saliency
/attention, and sensory motor..." in affected individuals, while regions of the brain that normally regulated each other (i.e. the salience network and

Furthermore, areas of the brain with less positive interconnectivity included temporal coupling between the left pallidum and right thalamus, and also
between the default mode network and affective network (Li et al., 2017). Normally, the pallidum acts by inhibiting pyramidal cells to help promote
sleep. This evidence has been supported in mouse models after discoveries showing that lesions inflicted on the external pallidum resulted in significant
increases in wakefulness, as well as significant "...fragmentation of non–REM sleep and wakefulness." (Li et al., 2017). The thalamus, which is also a
part of the ascending reticular activating system, also functions to help promote wakefulness (Li et al., 2017). Because of this, the observed decrease in
positive connections between the two regions (the thalamus and the pallidum of the subcortical region) could indicate that there may be diminished
"...mutual inhibitory effects..." between them (Li et al., 2017). Such mutual effects could increasingly suppress the thalamus during sleep, leading to
insomnia–like symptoms (Li et al., 2017).
As mentioned before, decreased positive connections were shown to exist between the default mode network and the salience network. One of the
major functions of the salience network observed among these studies was that it

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

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

The First Type Of A Person Essay
An individual can be one of three types of people when he is trying to remember someone. The first type is someone who would off the bat
recognize the other person as being familiar, but just cannot recall that person's name in that exact moment. The second type would be someone
who recognizes the person by name, but would not recognize him when he sees him in person. The third type is the person would be the star
individual who could correctly recognize the person and confidently greet the person by name. The majority of my friends, as well as myself, often
lean towards the first type of person. The feeling that the word, such as the name of a person, is within grasp, but for some reason, you are incapable
of verbalizing the word is known as the tip–of–the–tongue phenomenon. It is also frequently referred to as its abbreviated name: TOT. More often
than not, we are used to hearing about your parents or someone older who you know experiencing episodes of forgetting where they placed items,
such as their car keys, are. As troublesome as it may be, it is merely a symptom of growing older.
As we age, our memory will start to deteriorate along with our youthful appearance, causing us to have a harder time to recall information, such as
names. Information lasting more than 30 seconds in your mind gets moved from your working memory to your long–term memory where it is stored
for the rest of your life. Psychologists believe long–term memory is unlimited whereas short–term or

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?

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

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

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

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).

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,

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 &

We encounter new experiences everyday that mold us into who we are and how we respond to new experiences. Nurses who have overcome
many difficult obstacles may be better equipped for the clinical setting than those who have not encountered as many obstacles. For instance, a
nurse who has lost her father to a heart attack may respond differently than a nurse who has not. How we deal with encountering new situations
not only makes us human, but cultivates us into the different individuals that we become over our lifetime. Who we are in the present will be
changed in the future. When comparing our lives to a sculpture, we are never complete. We will always continue to be sculpted and molded as we
grow. My parents began shaping my life by introducing me to new people every day. Whether I was going to play group or visiting my mom at work

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.

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

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, &

Marketing : An Integral Part Of Any Business
Neuroscience in Marketing In recent times, Marketing has become an integral part of any business. Your business may offer the best products or
services in the industry, but without continuous projection of the product to the customers, the chances of your competitors taking over your products
is very high.
Marketing has evolved over the ages to a stage where every aspect of its technology is examined scientifically and improved techniques are applied to
win over the customers and retain them.
But what does the future hold for marketing?
Marketing, then and now
In the early 1950s and 1960s, marketing was production oriented and the quality of the production was the driving factor of marketing. Also, production
was demand oriented and creation of demand was not the primary focus of the manufacturer.
Later, as new production technologies started to develop, techniques evolved simultaneously to meet the needs of the customers and efforts were made
to maximize customization. Nowadays, a holistic marketing approach is used that integrates several aspects of marketing.
But the next major advancement in marketing is literally hacking the brain of the customer.
The next big step

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

It is important to note that Samantha and the many others like her are not forcing enculturation on their own brains; rather, it is a "drinking culture"

their collective causations, but retain some degree of personal agency (Bloch, 2011: 2–3), although how the balance between societal causation and
personal agency adjusts as brain enculturation progresses remains an interesting question.These three ethnographic examples that tell the stories of
Shelagh, Jemima and Samantha are but a small sample of how brains can be socially shaped or encultured and what this means. Other examples that I

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.

It is widely acknowledged by linguists that British English represents "stress–timed" language, whereas French represents "syllable–timed" language.
To detail the exact difference between the two, stress–timed languages have "equal duration between stresses," while syllable–timed languages show
"equal duration between syllable onsets" (Patel & Daniele, 2003, p. 36). With this basic piece of background information, Patel & Daniele hypothesizes
that syllable–timed languages have greater variability in the duration of its vowels as opposed to syllable–timed languages. Intuitively, this makes
sense since the temporal distance between syllables is smaller compared to the distance between the various points of stresses made in speech, which
can span multiple syllables and words. This logic gave birth to the "normalized Pairwise Variability Index" measure of speech rhythm or simply, nPVI.
As the term "pairwise" suggests, the nPVI takes the length between each pair of adjacent events in time, and calculates how much variability there is
among the various duration of vowels compared to the average duration over the entire series of events. The main strength of the nPVI measure lies in
the fact that it is a relative measure of events that take place over time, allowing one to take an nPVI value for both music and language and selectively

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

Insomnia Essay

  • 1. Insomnia Essay Neuroimaging has made it possible to assess abnormal metabolic functions responsible for insomnia. fMRI assists in targeting areas of the brain experiencing increased blood flow and neuronal activity. Studies that have analyzed the effects of insomnia using magnetic imaging techniques have concluded that there are characteristic deviations in brain structure and interconnectivity with regard to insomnia. In a recent review, ample evidence concluded that positive interconnectivity was present in regions of the brain responsible for "...wakefulness, emotion, worry/rumination, saliency /attention, and sensory motor..." in affected individuals, while regions of the brain that normally regulated each other (i.e. the salience network and default ... Show more content on Helpwriting.net ... Furthermore, areas of the brain with less positive interconnectivity included temporal coupling between the left pallidum and right thalamus, and also between the default mode network and affective network (Li et al., 2017). Normally, the pallidum acts by inhibiting pyramidal cells to help promote sleep. This evidence has been supported in mouse models after discoveries showing that lesions inflicted on the external pallidum resulted in significant increases in wakefulness, as well as significant "...fragmentation of non–REM sleep and wakefulness." (Li et al., 2017). The thalamus, which is also a part of the ascending reticular activating system, also functions to help promote wakefulness (Li et al., 2017). Because of this, the observed decrease in positive connections between the two regions (the thalamus and the pallidum of the subcortical region) could indicate that there may be diminished "...mutual inhibitory effects..." between them (Li et al., 2017). Such mutual effects could increasingly suppress the thalamus during sleep, leading to insomnia–like symptoms (Li et al., 2017). As mentioned before, decreased positive connections were shown to exist between the default mode network and the salience network. One of the major functions of the salience network observed among these studies was that it ... Get more on HelpWriting.net ...
  • 2. 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 ...
  • 3. 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 ...

  • 4. The First Type Of A Person Essay An individual can be one of three types of people when he is trying to remember someone. The first type is someone who would off the bat recognize the other person as being familiar, but just cannot recall that person's name in that exact moment. The second type would be someone who recognizes the person by name, but would not recognize him when he sees him in person. The third type is the person would be the star individual who could correctly recognize the person and confidently greet the person by name. The majority of my friends, as well as myself, often lean towards the first type of person. The feeling that the word, such as the name of a person, is within grasp, but for some reason, you are incapable of verbalizing the word is known as the tip–of–the–tongue phenomenon. It is also frequently referred to as its abbreviated name: TOT. More often than not, we are used to hearing about your parents or someone older who you know experiencing episodes of forgetting where they placed items, such as their car keys, are. As troublesome as it may be, it is merely a symptom of growing older. As we age, our memory will start to deteriorate along with our youthful appearance, causing us to have a harder time to recall information, such as names. Information lasting more than 30 seconds in your mind gets moved from your working memory to your long–term memory where it is stored for the rest of your life. Psychologists believe long–term memory is unlimited whereas short–term or ... Get more on HelpWriting.net ...
  • 5. 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.

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 ...
  • 6. 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 this paper he explains how he had 27 individuals in the first 9 months of a romantic relationship go through a series of pain trials where they were exposed to a heat block at various thresholds. While the pain was being applied they were told to focus in on a picture, either of their romantic partner or an equally attractive acquaintance, then they were told to rate their pain. The results really surprised me that it can be quantitatively determined that the pain they felt was less when viewing their partners. Mackey describes it as an analgesia affect, the brain dampening the nerves that would transmit the pain to the brain when view ones romantic partner. Many controls were put in place to make their experiment clear, for example the acquaintances and partners were rated equally attractive by a third party, the patients completed a mind–wiping arithmetic exercise after each trial, the pain scale for each patient was determined earlier through an empty trail and the skin area was cooled after ...

  • 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 ...

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 ...
  • 11. Personal Knowing Essay: Personal Ethics And Knowinging Personal Ethics and Knowing Paper Jessica Vernon University of Saint Joseph We encounter new experiences everyday that mold us into who we are and how we respond to new experiences. Nurses who have overcome many difficult obstacles may be better equipped for the clinical setting than those who have not encountered as many obstacles. For instance, a nurse who has lost her father to a heart attack may respond differently than a nurse who has not. How we deal with encountering new situations not only makes us human, but cultivates us into the different individuals that we become over our lifetime. Who we are in the present will be changed in the future. When comparing our lives to a sculpture, we are never complete. We will always continue to be sculpted and molded as we grow. My parents began shaping my life by introducing me to new people every day. Whether I was going to play group or visiting my mom at work in a local nursing home, I always loved to help people and be around people. It made me feel good to make people smile. As I began to get older, I realized that helping people not always meant doing physical labor such as sorting through boxes if an office was being moved. ... Show more content on Helpwriting.net ... Human dignity states that the patient's privacy will be protected, and the confidentiality of the patient and healthcare providers will be preserved (Taylor et al., 2011). I see this as extremely important with nurses as they are providing care first handedly. Because they see some gruesome and embarrassing things that should not get reported around the hospital, they should respect the privacy and desire for these patients to not get spoken about to other healthcare providers except on a need–to–know basis. Providing the privacy to these patients shows them that you respect them as an individual and that they feel they are being cared for uniquely (Taylor et al. ... Get more on HelpWriting.net ...
  • 12. 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 ...
  • 13. 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, & ...

Your business may offer the best products or services in the industry, but without continuous projection of the product to the customers, the chances of your competitors taking over your products is very high. Marketing has evolved over the ages to a stage where every aspect of its technology is examined scientifically and improved techniques are applied to win over the customers and retain them. But what does the future hold for marketing? Marketing, then and now In the early 1950s and 1960s, marketing was production oriented and the quality of the production was the driving factor of marketing. Also, production was demand oriented and creation of demand was not the primary focus of the manufacturer. Later, as new production technologies started to develop, techniques evolved simultaneously to meet the needs of the customers and efforts were made to maximize customization. Nowadays, a holistic marketing approach is used that integrates several aspects of marketing. But the next major advancement in marketing is literally hacking the brain of the customer. The next big step Neuroscience is the field of study where the response to products and consumer decision–making is understood at the level of body and mind. The Neuromarketing concept is based on a model wherein the major thinking part of human activity, including emotion, takes place in the subconscious area that is below ...

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 ...

  • 17. Brain Culture And Social Formation neuroscience, that reflects a growing realisation that the brain is not a wholly individual, biological and chemical product, but also one that incorporates elements of cultural and social formation. This social shaping and enculturation is explored in the next section of this paper.The effect of culture and society on the mind has long been widely accepted and has been studied by anthropologists and social scientists. It is, however, a different prospect entirely to posit that culture and society inform the make–up of the brain as well as the mind. It may be that this notion has elided academic consideration due to the incompatibilities of disciplinary focus points, objectives, philosophical starting–points, language and concepts of formation ...

It is important to note that Samantha and the many others like her are not forcing enculturation on their own brains; rather, it is a "drinking culture" that is the causative factor in their brains' enculturation. It must not be forgotten, however, that both Jemima and Samantha are not wholly the result of their collective causations, but retain some degree of personal agency (Bloch, 2011: 2–3), although how the balance between societal causation and personal agency adjusts as brain enculturation progresses remains an interesting question.These three ethnographic examples that tell the stories of Shelagh, Jemima and Samantha are but a small sample of how brains can be socially shaped or encultured and what this means. Other examples that I could include are the effect that social exclusion has in the partial causation of Alzheimer's disease (Wilson et al., 2007: 234), or the brain changes that have been observed in young men who have experienced prolonged exposure to that ultimate twenty–first century cultural phenomenon, internet pornography (Steele et al., 2013: 1). ...

  • 18. 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 ...
  • 19. Essay on Discovering Further Links between Language and Music Arguably, language is the one thing that sets humans apart from animals. The capacity to share thoughts and ideas through the spoken word allows humans to function as a group, enabling humanity to function as an entity greater than the sum of its separate individuals. Music shares similar properties, as it is also transmitted and perceived through sound. Both have the potential to connect people and are innate properties of the human being. The aim of this paper is to discover further links between the two based on empirical evidence. The main sources that will be consulted are articles produced by Dr. Aniruddh Patel, a pioneer in the field ofmusic psychology, with works ranging from music cognition to rhythm perception. The first study ... Show more content on Helpwriting.net ... It is widely acknowledged by linguists that British English represents "stress–timed" language, whereas French represents "syllable–timed" language. To detail the exact difference between the two, stress–timed languages have "equal duration between stresses," while syllable–timed languages show "equal duration between syllable onsets" (Patel & Daniele, 2003, p. 36). With this basic piece of background information, Patel & Daniele hypothesizes that syllable–timed languages have greater variability in the duration of its vowels as opposed to syllable–timed languages. Intuitively, this makes sense since the temporal distance between syllables is smaller compared to the distance between the various points of stresses made in speech, which can span multiple syllables and words. This logic gave birth to the "normalized Pairwise Variability Index" measure of speech rhythm or simply, nPVI. As the term "pairwise" suggests, the nPVI takes the length between each pair of adjacent events in time, and calculates how much variability there is among the various duration of vowels compared to the average duration over the entire series of events. The main strength of the nPVI measure lies in the fact that it is a relative measure of events that take place over time, allowing one to take an nPVI value for both music and language and selectively measure the variability of speech rhythm and musical rhythm within the same ...

  • 20. 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).
