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

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

Student ID number: 1704918 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

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

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

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

and damage to the prefrontal cortex is an area of research that over the years has shown to have negative effects on behaviour, cognition and emotions. The prefrontal cortex is situated on the frontal lobes of the brain and the frontal lobes are generally concerned with discouraging unsuitable and inapt behaviours. The 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

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

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

The brain's white matter, prefrontal cortext responds to judgment and impulse control is different in adolescent than adult. During adolescent, teenagers can easily be more frustrated and upset for no reason, while the adult are calmer with the emotion. This also true because when I was in my teenage years, if things wasn't going according to what I want, I would be upset with everything around me. In another experiment, young teenagers judge other's people's faces using part of the brain which determine
