Poverty And Brain Cortex Are A Correlational Study
Poverty and Brain Cortex Area: A Correlational Study
The extent of nature and nurture on the development of the human brain has long been studied by neuroscientists and cognitive psychologists. Up to
what degree does each variable play in each function of the brain? A group of psychologists recently conducted the largest correlational study looking
for the relationship between socioeconomic status (SES) of a family and its effects on the brain morphology and behavior of the children raised in them.
Socioeconomic disparities have been shown to have profound effect on the cognitive development of a child, but this study went beyond the behavioral
effects to the anatomical effects of one's SES. Similar studies have looked at the anatomical differences among various race/ethnic groups but no study
has been done linking socioeconomic status–parental education and family income specifically. This was the first attempt to separate these two variable
and look at their correlation with cognitive development.
The study involved 1099 participants ages 3 to 20 years old from various cities of the United States. The main purpose of the study was to study
socioeconomic factors and brain morphology. Preliminary data of socioeconomic status was collected on the average parental education and family
income. Everyone also participated in Magnetic Resonance Imaging (MRI) and had their heads scanned to look at the brain's morphology. The
secondary variable that the researchers measured was the

Mutation In The Prefrontal Cortex
It is believed that a mutation in the prefrontal cortex predisposes some people to violence. The frontal lobe is what we use to make decisions and,
when fully developed, allows us to think carefully about our actions before we take them. An alteration in the prefrontal cortex may make us
susceptible to impulsive and rash behaviors. For example, teens tend to be more reckless than adults. The teen frontal lobe is not fully formed, which is
the reason for this outcome. Teens also tend to rely on their amygdalas to make decision. The amygdala is the center for powerful emotions, such as
anger, jealousy, and guilt. For example, psychopaths have been found to be void of guilt and regret as a result of "the amygdala [being] less activated

Auditory Cortex Failure
If I were to get into an accident, and had to choose which part of the brain I would be okay with being damaged, I think I would have to choose the
Auditory Cortex. Damage to the Auditory Cortex in humans means the loss of awareness in sound. If the damage was severe there is a chance I
would go completely deaf. However, there is the slight chance that I could still have reactions to sounds. I may still be able to tell the difference
between high and low pitch frequencies in the sounds. I can also possibly be able to tell which direction a sound is coming from. There is also a
chance it would cause me to have balance issues, and excessive ringing in the ears. Most of the time this type of damage is permeant. I think that I

Interaction Between The Primitive Brain And Neo-Cortex
Question #1 In this video, Mark discusses the interaction between our 'primitive brain' and our 'neo–cortex', explaining how the two work together to
form opinions of other people. How does Mark's explanation of this interaction between our primitive brain and neo–cortex help us to understand the
following quotation from our course textbook? "Changing a buyer's attitudes and beliefs is the most difficult challenge a salesperson faces." Our
primitive brain make quick decisive judgements about the people around it based on the behaviour another is displaying. We pick up details and facts
about a person to be categorized either as a friend, enemy, or sexual partner/approachable or not approachable. The neo–cortex uses the categories from
the data you collected to push friend or enemy, basically making up stories in favor of what you primate brain unconsciously tells you. The video can
help to understand the quote from the textbook say, "Changing a buyer's attitudes and beliefs is the most difficult challenge a salesperson faces."

The Prefrontal Cortex: A Key Role In Neurocognitive Analysis
The prefrontal cortex plays a major key role in Neurocognitive Networks of impulsivity and transition to addiction. The cortex regulates the reward and
its involvement in higher–order executive functions, such as self–control, goal oriented behavior, and response inhibition. According to "Goldstein and
Volkow" reviewed neuroimaging data of specific prefrontal cortex regions and their roles in neuropsychological mechanisms that underlie the relapsing

The Effects Of Sex Hormones On The Development Of...
Abstract
Gender differences have been recorded by researches from single neurons in the cell to system level processes (Cahill 2006), and certain scientists
proposed that sex hormones influence the development of prefrontal cortex, and this is supposed to be the cause of the differences in working memory
performance (Duff & Hampson, 2001). This study further investigated the existence and nature of this gender difference. A sample of 497 Monash
University psychology undergraduates (385 females and 112 males; ages 18 – 64) were recruited for this study. Working memory performance was
tested with online 'spatial working memory ' test, and 2D:4D finger length ratio was used as an indirect measure of sex hormone levels. The results
revealed no sex differences in the working memory performance, but variance in 2D:4D ratio – females had a larger ratio than males. Memory reaction
time was negatively correlated with 2D:4D ratio, thus, females had a quicker reaction time.
Introduction
Differences related to gender in spatial memory are most widely described and studied of cognitive sex differences. In 1974 Maccoby and Jacklin
established that males usually perform better than females in measures of spatial performance, and this discovery has been constantly replicated in
multiple studies covering various developmental stages (McGivern et al. 1997; Lewin et al. 2001) and spatial tasks (Dabbs Jr. et al. 1998; Driscoll et
al. 2005).
While many researches proved the

An Examination of Cross-Modal Reorganization in the...
The brain is capable of changing itself, particularly as a consequence of experience in early life. Following early–deafness, auditory cortex undergoes
cross–modal reorganization to exhibit visual responsiveness; this is accompanied by enhanced visual abilities. The objective of Lomber et al.'s (2010)
study was to establish a causal connection between cross–modal reorganization of specific regions of auditory cortex and enhanced visual abilities. To
identify the enhanced visual abilities, the researchers compared the performance of adult hearing to the performance of congenitally deaf cats on seven
visual psychophysical tests. They tested visual localization, movement detection, grating acuity, Vernier acuity, orientation discrimination, detection of
motion, and velocity discrimination abilities. Following the completion of the tests, the researchers found that early–deaf cats performed better than
the hearing cats in peripheral visual localization and visual motion detection abilities. For the other tests, the performance of the congenitally deaf cats
was not significantly different from the performance of the hearing cats. To investigate if the cross–modal effects are evenly distributed across auditory
cortex, Lomber et al. (2010) employed cooling loops to differentially deactivate specific regions of auditory cortex. Ultimately, they suggested that the
posterior auditory field (PAF) mediated enhanced peripheral visual localization

During the development of the human brain, the layers of the cerebral cortex are formed by migrating neurons which come from specialized
proliferating regions lying deep in the brain. This neural migration comprises neurons moving as far as one thousand times their own body lengths
before they arrive at their destination. During this developmental process, the cortex is divided into six organized layers. In Lissencephaly, this
organized cortical layering is disrupted and instead forms four unorganized layers1. It is a severe developmental brain disorder which is characterized
by a smooth brain with an abnormal thick cortex, enlarged ventricles, and very few or no gyri2. At the basis of this disease lies failure of proper

The C–Terminal Ser/Pro–rich domain has no known function in microtubule binding as of yet. Rather, it functions as an interaction site for other
molecules. This suggests that DCX is involved in signaling pathways: DCX is phosphorylated by both Cyclin–dependent kinase 5 (CDK5) and c–jun
NH2–terminal kinase (JNK)7,8 at the Ser/Pro–rich domain. Phosphorylation of DCX by CDK5 controls and localizes DCX to fine perinuclear
microtubules but not to microtubule bundles in proximal processes. This phosphorylation is developmentally regulated by p35, the major activating
subunit for CDK58. At the growth cones, DCX is co–localized with JNK. Phosphorylation of DCX by JNK facilitates neurite outgrowth during
differentiation, a process which is important in migration. Additionally, DCX interacts with JNK–interacting protein–1 (JIP–1), a scaffold protein that
facilitates its phosphorylation by JNK and furthermore might provide a crosstalk with the reelin pathway7,9. A defective cortical layering phenotype
is also observed in individuals with mutations in the REELIN gene. Other phosporylation proteins for DCX are PKA and MARK. Dcx/microtubule
interactions are negatively controlled by PKA and MARK at the growth cones.10 Unlike the other two kinases, PKA and and MARK does not
phosporylate DCX at the Ser/Pro domain, but at several other sites, with the most important one being S47. The C–terminal region of DCX regulates

Essay about Lesions of the Prefrontal Cortex
Lesions of the Prefrontal Cortex
The prefrontal cortex is involved in a wide variety of functions. It is known as the area of the brain which has
"executive control", taking input from other areas of the brain and combining and applying those functions (Kalat 2004).
Lesions to the prefrontal area can greatly impair overt behavior of an inflicted individual. These deficits are dependent upon the severity of the lesion
and the specific region of the prefrontal cortex in which the lesion resides (ventrolateral, dorsolateral, orbitofrontal, and anterior prefrontal)(Eslinger
2003).

Persons with left hemisphere lesions are often depressed and display inhibition which includes apathy, flattened affect, withdrawal, narrowing of
interests(Trauner 2001). Patients with right or left hemispheric lesions may experience disinhibition which includes euphoria, impulsivity, and
irritability, inappropriate emotional responses and impaired judgment (Trauner 2001). Intellectual capacities can remain preserved, and individuals with
prefrontal damage can score normal–average intelligence on standard IQ tests (Eslinger 2003). Cognitive deficits which do appear relate to attention,
self–regulation, inhibition, planning, problem solving, critical thinking, organization, working memory, self–awareness and self– monitoring, and
goal–directed behavior (Eslinger 2003).
Available cases of early prefrontal cortex damage provide evidence for the importance of this region in psychological development (Eslinger 2003).
Anderson (1999) discussed the important cognitive and behavioral deficit differences between childhood onset of prefrontal cortex lesions and adult
onset lesions to the prefrontal cortex. Adults who experience a lesion to the prefrontal cortex have had years of normal cognitive and social behavior

The prelimbic cortex (PL) is an important structure involved in several stress–related functional processes, such as cardiovascular, hormonal and
behavior responses. Since there is an increased expression of central angiotensinergic receptors during stressful situations, we tested the hypothesis that
such angiotensinergic neurotransmission in the PL modulates the autonomic responses evoked by restraint stress in rats, such as blood pressure and
heart rate increases, and reduction in tail temperature.. Male Wistar rats were used and guide cannulas were bilaterally implanted in PL for
microinjection of vehicle or drugs. A polyethylene catheter was introduced into the femoral artery for recording of cardiovascular parameters using a

Prefrontal Cortex Research Paper
The prefrontal cortex is the most anterior region of the frontal lobe. It occupies one–third of the cerebral cortex and is key for executive functions such
as problem solving, working memory, and emotional control. It is also crucial in decision making and the expression of personality. The prefrontal
cortex is imperative for efficient cognitive functioning; damage can result in severe impairment to skills such as emotional regulation, moral behavior,
and empathy. In addition, the prefrontal cortex is a sub–region of the frontal cortex; this includes the primary motor cortex and premotor cortex in
addition to the prefrontal cortex areas, which are located more anteriorly. The prefrontal cortex itself can be divided into three sectors– the

To compare between the effect of stimulating the motor cortex (M1 region) using Transracial stochastic noise stimulation (TSNS) and transracial
direct current stimulation, and to quantify the effect of the TSNS on the brain activity. In order to measure the effect we need to conduct two studies.
First experiment is done inside the FMRI scanner, to record rCBF (regional Cerebral Blood Flow) for healthy control subjects while stimulating the
M1 region using TDCs and TSNS. Second experiment is to measure the effect of TSNs and TDCs using TCD, which measures the change inBrain

Rational and Hypothesis:
Most of stroke patients suffer from dysfunction in some of the brain activities; one common dysfunction is arm or leg paresis. Therefore the long term
goal is to use noninvasive electrical stimulation to improve the function for arm paresis stroke and TBI patients. The targeted population is individuals
that have post stroke/TBI dysfunction. Previous studies showed that the stimulation of the motor cortex (M1) region using direct electrical stimulation
increases brain activity and help improves brain function. However Direct current stimulation has several limitations, for instance the polarity of the
electrodes effects the measurement, since the brain region that attached to the anode will be excited and the region that is attached to the cathode will
be inhibited. Therefore we are introducing a new novel method

Any displacement of the tympanic membrane causes changes in pressure waves which is transmitted by tiny bones. 2–Middle ear: Sound waves
traveling through the ear canal will hit the tympanum. This wave information travels across middle ear cavity via a series of delicate bones: the
mallus (hammer), incus (anvil) and stapes (stirrup). These ossicles act as a lever converting the lower–pressure eardrum sound vibrations into
higher–pressure sound vibrations to smaller membrane called the oval window. Higher pressure is necessary because the inner ear beyond the oval
window contains liquid rather than air. The auditory reflex of the middle ear muscles helps protect the inner ear from damage. The middle ear still
contains the sound information in wave form; it is converted to nerve impulses in the cochlea. 3–The inner ear: The inner ear consists of the cochlea.
The cochlea has three fluid–filled sections, and supports a fluid wave driven by pressure across the basilar membrane separating two of the sections.

The Fundamental Ability Of The Prefrontal Cortex
The fundamental ability of the prefrontal cortex is to represent information not currently in the environment; its role within the temporal lobe is to
create a mental sketch pad within an individuals mind (Goldman–Rakic). It regulates short term and long term decision making and helps individuals
focus thoughts and houses active working memory. Due to the funtions that the prefront cortex displays, damage to this area commonly leads to
multiple problems such as the inability to plan or even behaving in ways that are not seen as sociably acceptable. Individuals who have suffered
damage their prefrontal cortex are oblivious to future consequences and their actions tend to be guided by immediate results (Bechara, Damasio,
Damasio, & Anderson, 1994). The premotor cortex is involved in learning and executing complex movements that are guided by sensory information.
Many studies suggest that the premotor cortex is involved in using arbitrary stimuli to indicate what movement should be made. The relationship
between stimuli and movement are arbitrary and must be learned. For example Nowak et al (2009) found that participants would adjust the strength
of their grip when picking up an object based on the colour of a dot. Once again we look at how these areas function after being damage. For
example damage to the premotor cortex may result in a range of problems such as apraxia, which is the inability to carry out actions that require skill
that previously could be performed.

In another experiment, young teenagers judge other's people's faces using part of the brain which determine to recognize fear and alarm, this can be

The Functions Of The Talamus In The Midbrate Brain
Translated from Greek thalamus means "chamber" and is a midline symmetrical structure of two halves, with the vertebrate brain, situated between the
cerebral cortex and the midbrain. The functions of the thalamus is to relay the sensory and motor signals to the cerebral cortex and the midbrain, and
the regulation of consciousness, sleep, and alertness. The thalamus is located in the forebrain superior to the midbrain, near the center of the brain, with
nerve fibers projecting into the cerebral cortex in all directions of the brain. The surface of the thalamus constitutes the upper part of the lateral wall of
the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic

The Orbitofrontal Cortex and Social Behaviors
Within the realm if biological psychology, there are two known types of behaviour. One being regulatory and the other, non
–regulatory. Regulatory
behaviour is controlled by the hypothalamus and maintains homeostasis in the body by continuing the processes of the vital body systems. An example
of this could be; eating. Regulatory behaviour occurs in a person's everyday life without them noticing that it happens. Non–regulatory behaviour, on
the other hand is not controlled by a homeostatic mechanism in the hypothalamus but rather in the orbitofrontal cortex. Example of non–regulatory
behaviour include; parenting, aggression and social behaviour. (Swartz, L. et al, 2011)
The orbitofrontal cortex is a part of the brain that is located superiorly to the eye socket and inferiorly to the frontal lobe. Part of its function is that it is
involved in the regulation of reward–orientated behaviour, inhibiting unwanted behaviour as well as being involved with emotions and decision
making (Swartz, L et al, 2011).
The orbitofrontal cortex is greatly associated with social behaviour. With reference to (Beer, J. S. et al), there are two theories that are coherent social
short–comings associated with the orbitofrontal cortex. These are one, "deficient emotional systems" and two, "self–monitoring". Deficient emotional
systems or the lack of behavioural monitoring can be characterized by the "somatic marker hypothesis". This theory suggests that the orbitofrontal
cortex is an imperative part

Primary Visual Cortex
Throughout history, a human being was always reliant on the primary sensory areas. An ability to communicate and contract languages is
considered to be a unique ability of human nation as no other species show an equal amount of complexity in terms of the structure and sound
combination. On the other hand, primary visual cortex provides a skill set in order to identify the objects presented in the world, the distance
towards them as well as to design a set of actions in order to incorporate some items such as a stone or a pen. The understanding of these systems is
crucial, especially for those who suffer from strokes and tumors and as a result lost the ability to visually recognize objects or hear other people. This

The system consists of the eyes where the information is collected, geniculate lateral nucleus and visual cortex. The visual cortex could be subdivided
into the primary visual cortex and the striate cortex. This sensory system is located at the back of a brain parts of which are located in both hemispheres.
Recent studies obtained a sufficient amount of information in order to construct the two–stream hypothesis, which describes the ventral and dorsal
streams. The ventral stream begins at the primary visual cortex and goes to the inferior temporal cortex. Main functional responsibilities of this area
include identification of objects and the emergence of the long–term memory the origins of which are placed in this area (Rauschecker, Josef P and
Sophie K. Scott 722). Dorsal stream also begins at the primary visual cortex and ends at the posterior parietal cortex. It is mainly responsible for the
body part control required in order to manipulate an object. The research shows that these "what" and "why" systems are not directly related, and the
damage in one affect the other only to a certain extent. It could be explained by the fact that that input is transformed differently via action and

The Development Of The Cortex
The development of the cortex is a delicate balance between proliferation, differentiation and migration of neural progenitors (NPs). Throughout
developmental process, various cellular mechanisms ensure that NPs are differentiating into the correct cell subtypes, migrating to their correct
regions, and forming the correct cortical and sub–cortical layers. The cortex is comprised of both excitatory and inhibitory neurons, which interact
within neuronal circuits to mediate cortical functions. Though both types of neurons reside in the cortex, they arise from different embryonic brain
regions, and from different neural progenitors. Excitatory neurons are generated from neural progenitors residing in the ventricular zone (VZ)

X94 cells are located exclusively in layers 4 and 5, and martinotti cells can be either calretinin (CR) positive or negative, and are bursting/non–bursting
respectively. NPY+ originate from both the MGE and CGE, and can also be SST+. In the adult mouse brain, they are found mostly in layers 2/3/6,
but can exist in all layers (Karagiannis et al., 2009). Additionally, they are often activity dependent, and increases expression upon neuronal activity
(De Marco Garcia et al., 2011).
Failure to form proper cortical layers has been observed in patients with developmental disorders, such as ASDs and SZ(Stoner et al., 2014). Though
less populous than excitatory neurons in the neocortex, GABAergic interneurons are essential to the functionality of the nervous system. Though the
precise genetic components causing autism still elude us, there are intriguing molecular hypothesis for this disorder. One such hypothesis is the
GABAergic hypothesis of autism. There is increasing evidence that deficits in interneurons are related to psychiatric disease. Post–mortem studies of
schizophrenia patients revealed reduced GAD67 expression, and decreased PV and GAD67 mRNA (Benes et al., 2007; Curley and Lewis, 2012).
Additionally, 30% of patients with ASD have epilepsy, and 30% of patients with epilepsy have ASD. This co
–morbidity suggests a potential disruption
in the E/I balance of the brain, which often results in epilepsy. Additionally, many ASD risk genes have been associated with

Dorsolateral Prefrontal Cortex Case Study
Overview:
The Dorsolateral Prefrontal Cortex (DLPFC) is part of the frontal lobe, one of the most complex parts of the brain and among the last areas to develop.
According to numerous neuroimaging studies, it may not be fully mature until a person's mid–20s. The DLFPC has numerous connections with other
parts of the brain and helps integrate information from different systems.
The DLPFC is involved in higher–order processing and executive functions like working memory, planning, attention, and self–regulation. These
functions are crucial for everyday tasks like learning, decision–making, and socializing.

The Four Lobes Of The Cerebral Cortex
The Four Lobes of the Cerebral Cortex
The human brain is very complex and is constantly being studied. Scientists have named different portions of the brain and try to understand what the
different areas control. The Cerebrum is the largest part of the brain and contains most of the body's voluntary functions. (ChalkSMART, 2012) The
Cerebrum contains four lobes, the occipital lobe, the parietal lobe, the temporal lobe, and the frontal lobe. The lobes are named for the skull bones
they correlate with. Scientists have studied which lobes affect different functions of the body. According to McCaffrey (1997/2014), it is important to

The occipital lobe is the main visual area of our brain, the optic nerve from the eye sends signals here and we experience shapes, colors, and motion
around us. (Franzoi, 2014, p. 63) Also, "a lot of memory is stored in this area." (McCaffrey, 1997/2014) Damage to this area could cause blindness even
if the eyes and optic nerve are healthy. (Franzoi, 2014, p. 63)
Parietal Lobe The parietal lobe is located in front of the occipital lobe. This area of the brain is associated with touch sensation, smell, and taste.
(Franzoi, 2014) The parietal lobe is also involved in writing and in some aspects of reading and recognition of visual symbols. (McCaffrey, 1997
/2014) Damage to this region could mean a person could not feel an object placed in their hand.
Temporal Lobe The temporal lobe is below the parietal lobe, near the temples. Long–term memory formation, anxiety, hearing, language word meaning
and appreciation of smell is all associated with this lobe. (Franzoi, 2014) (ChalkSMART, 2012) (McCaffrey, 1997/2014) Damage to this area,
especially to the respect of the left lobe called Wernicke's, could result in difficulty understanding words and sentences. (Franzoi,

The Anatomy Of The Cerebral Cortex
The cerebral cortex is a vital component of the brain, and is responsible for bodily functions that would be difficult to live without. To have a more
suitable expertise of the cerebral cortex scientist divided the brain into for lobes contingent to the purpose of what each lobe is responsible for. Each
lobe of the cerebral cortex plays an essential role in humans every day life. If one of the lobes were absent being successful at the University of
Oklahoma would be difficult if not unviable. The cerebral cortex has numerous functions, each being unique to how it affects the human body. Scientist
categorized the cerebral cortex into four different lobes depending on their purpose to improve our understanding and assist our research of the
cerebral cortex. The four lobes of the cerebral cortex are the Frontal, parietal, occipital, and temporal lobes. The frontal lobe, located at the front of the
brain close to our foreheads, is in charge of more intricate and complex work of the brain. It manages jobs such as contemplating, making decisions,
and planning, but the frontal lobe is also in charge of emotions and communication proficiency. The frontal lobe is an important component of the
cerebral cortex and is associated in most every day life experiences. Whether it be deciding on an outfit for the day, or having a conversation with a
friend. The parietal lobe transfers our senses like contact, temperature, and aroma into things the body can feel and comprehend. If

prefrontal cortex usually play a fundamental role in one's decision making, organisation of information and planning. Hence, any damage to the
prefrontal cortex leads to a lack in decision making and an inability to plan.
Two key components to an impaired prefrontal cortex are drugs and alcohol (Rogers et ... Show more content on Helpwriting.net ...
The young adolescent experienced profound changes in his behaviour in terms of aggression and agitation, nevertheless, he still maintained his
cognitive abilities such as memorising and engaging in political knowledge. This study is also based on a real life case study, which are unique and
cause some difficulties when making generalisations. However, this study supports the conclusions drawn by Anderson S.W, Damasio H, Traeel D and
Damasio AR (2000) who found that prefrontal lesions in during early development can cause serious social problems, yet these individuals can have
ordinary cognitive capabilities such as academic attainment and good

Dude Where's My Front Cortex Analysis
The article "Dude, Where's My Frontal Cortex?" by Robert Sapolsky talks about the delayed maturation of the frontal cortex in teenagers and how the
underdeveloped frontal cortex is the cause of erratic behavior of teenagers. Sapolsky explains to the reader how the frontal cortex does not fully
develop until the age of twenty for a person and how that part of the brain is important for extensive reasoning, impulse control, and emotional
regulation. He shows the reader how particularly emotional situations affect both a teenager and an adult differently due to either having or not having
a matured frontal cortex. This example that he uses allows for the reader to see how a teenager responds to situations with extreme thoughts and
behavior which

training. Mice infused with anisomycin (n= 12) immediately after conditioning showed impairment in contextual fear memory compared with
vehicle–infused animals (saline, n=18) when tested 24 hours after CFC training (DF=28, F=7.19, t–test: p< 0.05) (Figure 2A). Surprisingly, irrespective
of the overall decrease in freezing percentage, mice injected with anisomycin did not show any statistical difference in the level of freezing within the
first 2 minutes of the test (Figure 2B). By the third minute of testing, ANI–injected mice show a significant decrease in their level of freezing, showing
statistical significant differences until the end of the test (drug Г— memory minutes of test DF=28, F=13.16, t–test p< 0.01; DF=28, F=7.66, t–test p<
0.01; DF=28, F=5.46, t–test p< 0.05) (Figure 2B). These results suggested that new protein synthesis at PrL cortex is critical for the encoding of
contextual fear memories.
To further understand new protein synthesis at PFC, we asked whether other subregions of PFC are also critical for encoding of contextual fear
memories. To address this question, we studied the role of cingulate cortex 1 (CG1) region of PFC in encoding. We injected anisomycin to inhibit
protein synthesis at CG1. Four separate groups of animals received anisomycin and saline infusions into the adjacent CG1 (Saline, n= 8; ANI, n=6;
Figure 2 C and D). As in the case of Prl cortex, anisomicyn was injected shortly after CFC training. Measurements of freezing at 24 hours

Prefrontal Cortex Summary
The Prefrontal Cortex is involved in planning of behavior, attention and judgment and the orbitofrontal cortex plays an important role in emotions
and impulse control. This is related to the article because in order for people to feel empathy, their orbitofrontal cortex has to function. To act the
way people do when approached by their competitors, people need their prefrontal cortex to act how they would. The article does not necessarily
contradict any of the content we learned but it gives examples of how there structures in our brain aid in our behavior and in the way we act. If these
parts of our brain weren't working, people would experience impulsiveness, antisocial behavior, experience of various emotions and deficits in the

The Cerebral Cortex
Q1: The cerebral cortex is a highly organized, six layered structure (L1–6) with a variety of excitatory and inhibitory cell types. Excitatory
(glutamatergic) neurons make up 80% of the cortex and consist of pyramidal and spiny stellate (granule) neurons. Inhibitory (GABAergic) neurons
make up only 20% of the cortex and consist of four different subtypes: non–fast spiking serotonin expressing GABAergic neurons, martinotti cells,
basket cells, and chandelier cells (Petersen & Crochet, 2013; Shipp, 2007). The total number of neuronal cells in the adult human cortex is 21.4 billion
for females and 26.3 billion for males; however, there are also non–neuronal cells present in the cortex (Pelvig, Pakkenberg, Stark, & Pakkenberg,
2008). The major non–neuronal cells are glial cells and consist of: oligodendrocytes (75% of non–neuronal cells), astrocytes (20%) and microglia (5%)
(Pelvig et al., 2008). The layering of the cortex is highly organized, with specific cell bodies located in each layer. Layer 1 receives input from other
cortical layers as well as subcortical layers and is comprised solely of inhibitory neurons, although there are axons and dendrites that project onto these
neurons in addition to non–neuronal cells (Petersen & Crochet, 2013). Layers 2/3 are difficult to differentiate from one another, and often referred to
as the supragranular layers. These layers contain medium sized pyramidal cells that have densely packed and highly aligned apical dendrites and make

Ventromedial Prefrontal Cortex
Structures and Function of the Frontal Lobe
The frontal lobe contains two key structures that have a great impact on mood, behavior and judgment. These structures are located in the outer area of
the cerebrum towards the front of the skull (Carlson, 2013). This paper will discuss the function and structure of the Ventromedial Prefrontal Cortex
(including the orbitofrontal cortex) and the Dorsolateral Cortex.
The Function of the Ventromedial Prefrontal Cortex
Many studies have concluded that the ventromedial prefrontal cortex (or vmPFC) appears to provide the inhibition of emotional responses (Carlson,
2013). This region of the brain provides the mind with the faculties of self–restraint or self–control.
Behavior Affected by Damage to the Ventromedial Prefrontal Cortex... Show more content on Helpwriting.net ...
For example, a study conducted by the University of Iowa College of Medicine found that when this portion of the brain is damaged, individuals were
more susceptible to believing misleading advertising, thereby triggering the person to make a purchase (Asp et al., 2012). Another study from the
University of Iowa found that damage to the vmPFC seems to be connected with patients who suffer from drug or gambling additions (Bechara, 2003).
Neurotransmitters Associated with the Ventromedial Prefrontal Cortex
Glutamate and Gamma–aminobutyric acid (or GABA) are the main neurotransmitters associated with this part of the brain. Through the use of
magnetic resonance spectroscopy (MRS) researchers have been able to measure these particular neurotransmitters in order to predict human behavior
when it comes to value guided decision making (Jocham, Hunt, Near, & Behrens, 2012).

The Controller of Humans: The Brain Essay
The human brain is composed of many important parts of everyday life. The exterior part of the brain has 9 part in which include are divided into
different sections, lobes, cortex, and areas. Within the lobes, it includes frontal, parietal, occipital, and temporal lobes. In cortexes, it has the motor
cortex, and the sensory cortex. Within the areas section it includes Broca's Area. The cerebellum is a small version of thebrain, and the cerebrum is the
like the whole brain. Although the brain is about three pounds blood flows through the brain about 750–1,000 milliliters (mL) per minute, (Disabled

Largest of the lobes, handles brain thinking functions (Frontal Lobe: (n.d.)). This lobe is located in front of the central sulcus (Lobes of the Brain, (n.d.)).
The cortex responsible for coordination of planning, control, and executing voluntary movements is the motor cortex. Motor areas are located in both
hemispheres meaning it is located in between. The motor cortex of the left hemisphere control right side of the body. The motor cortexes of the right
hemisphere control the left side of the body. Three parts make up the motor cortex. Which are the primary motor cortex, the premotor cortex, and the
supplementary motor area (The Motor Cortex. (n.d.)).
Broca's Area generates speech, writing, language processing and comprehension (Cold Spring Harbor Laboratory, (n.d.)).Named after French scientist
Paul Broca. Scientist believe that we speak with the left–brain. Located in the front part of the left hemisphere. Lies specifically in the third frontal
convolution. Broca's Area contains motor neurons involving the control of speech. (Encyclopedia of Britannica, (n.d.)).
Within the lobes, the parietal lobe lies in that category. This lobes function is to stimuli touch, pressure, temperature, and pain (Lobes of the Brain,
(n.d.)). This parietal lobe is divided into two parts, superior parietal and the inferior parietal lobe. Neurons receive sensory information from skin and
tongue. This then processes information from the ears and the eyes (Parietal Lobe, (n.d.)).

Premotor Cortex Argumentative Analysis
The brain has many different parts and functions which do many different tasks. The Premotor Cortex is an area in the brain responsible for planning
movement. Signals travel to the back of the brain then are processed and sent down a pathway to the Premotor Cortex to complete an action.
Researchers have found ways to simplify the process in which information is received in the Premotor Cortex. The New York Times article gives
information about two scientist's discoveries, the testing of their discoveries, the results of the tests, and the benefits of their ideas.
Two researchers from the University of Rochester have found a way to reduce the process of completing actions. Bodies complete actions through
signals which are broadcasted in the visual center in the back of the brain then redefined and sent to the Premotor Cortex. The shortened system directly
plants electrodes in the Premotor Cortex. These electrodes in the Premotor Cortex are sent bursts of electricity which send signals to the brain. The two
analysts were able to discover a more efficient way of completing movements. ... Show more content on Helpwriting.net ...
Monkeys were put in front of a table with a button, a spherical knob, a cylindrical knob, and a handle with lights. The monkeys would extend their
hands and do the action related to the object whose light came on. The monkeys would receive an electricity burst when the light came on and reward
after successfully completing the action. As time passed the lights dimmed and then turned off. Without the lights the monkeys only had the indicators
from the electrodes to help them. Monkeys performed experiments to test the scientists new method of executing

Does Dysfunction Of The Prefrontal Cortex Lead Antisocial...

Does dysfunction of the prefrontal cortex lead to antisocial behaviour?
Word count: 984 Antisocial behaviour (ASB) broadly encompasses human character traits and behaviours that are generally viewed as unpleasant or
immoral, such as reduced empathy, aggression and violence. Consequently, ASB is unconducive to forming healthy interpersonal relationships and
functional living and on a large scale is socio–economically detrimental to societies. Therefore, research into ASB's aetiology is important for
potentially informing its prevention and management and in turn reducing its negative outcomes. This essay investigates the possible causal role of
prefrontal cortex (PFC) dysfunction and structural abnormalities in ASB, focusing on specific PFC subregions; as well as the roles of other brain
regions, genetics and the environment. It argues that there is significant evidence that the dysfunction of several brain regions, including the PFC and
areas of other lobes, can lead to ASB. The underlying reason(s) for the dysfunction may be brain damage and/or genetic and environmental influences.
The PFC, the rostralmost region of the frontal lobe, as part of neural circuits that include other cortical and subcortical regions, is widely regarded as
the neural substrate for many executive functions (EFs), at least some of which are impaired in ASB. EFs include working memory, planning,
decision–making and inhibition (Eslinger,

Summary: What Does The Insular Cortex
Scientists recently identified a region in the brain that plays a key role in smoking cessation: the insular cortex.
What Does The Insular Cortex Do?
The insular cortex is located between the temporal and the parietal lobes of the brain and is associated with a vast array of cognitive functions, from
high–level human consciousness processes to those of primal self–regulation and bodily homeostasis.
On the one hand, the insular cortex is associated with basic motor control like swallowing, hand–eye coordination, and speech articulation. It is also
related to heartbeat, blood pressure, the immune system, the digestive system, and the intake of information from each of the five senses.
On the other hand, the insular cortex is especially linked to emotional processing. The region has been highlighted for its role in self–awareness,
agency, and bodily ownership as well as for its relationship to empathy and the consciousness of interpersonal experiences. It is also where orgasms,
social norm violations, and the sensation of pain are evaluated in the brain.
This insular cortex seems to straddle an interesting divide between the brain functions that we traditionally consider animalistic, ... Show more content

Frontal Lobe Research Paper
The Brain's Frontal Lobes Actions
The frontal lobe and the following other parts of the frontal lobe section of the brain have many functions. The frontal lobe part of the brain connects to
many other structural parts of the brain, connected to mini sections of which creates different effects to the lobe. Which are the prefrontal cortex,
orbitofrontal cortex, primary motor cortex, and premotor cortex.
The prefrontal cortex is located within the frontal lobe, but it takes up the majority of the lobe. The function of the prefrontal cortex is the crucial
performance, and skill it provides within the brain which requires intelligence. The brain is located in many different subjects, such as a human,
mammal, and animal. When discussing the prefrontal cortex, it's known to many that it's larger in certain primates and it tends to be that way but not
in mammals. It is also known to be larger in the human brain compared to other primates' brains. The reason of this is because of the high amount of
the level planning which is correlated by the members that have different species. The majority of the mammal population operate on most likely the
first instinct, which they don't live within complex social groups. The primates are the ones with the complex with both male and female which the

This area is known as the anterior in which includes the medial part in the prefrontal cortex. A human individual that could possibly run into damaging
this area of the brain could potentially have the normal and/or superior intelligence. Which is usually tested by IQ programs, and studies. The IQ test
could lack some rudimentary concepts of the many manners and the appropriate actions within the social contexts. Then it becomes possible to lose all
risk of the aversion which makes it clear of the knowledge of the bad consequences.

Prefrontal Cortex Research Paper
Creating the world's first Z–Bomb, would have to be the most dangerous thing that could happen to humans. Turning them into Zombies, it would
entirely change the characteristics of a human being and its brain. Although both living, Zombies have drastic defects towards certain aspects of the
body. This Z–bomb won't necessarily turn humans into zombies, but rather give humans zombie–ish characteristics. For starters, the Prefrontal Cortex
would be affected. Meaning that it would be harder for these 'Zombies' to have complex cognition as well as a properly functioning emotional system.
When stated that zombies have 'extraordinarily high pain tolerance', this means that their nociceptors were damaged, which is responsible for pain
tolerance.
