What are the common results of prefrontal bark damage?
The prefrontal cortex is located in the frontal lobes of the brain. Functionally, the front lobes are involved in inhibition of inappropriate behavior, decision -making and planning. For this reason, damage to the prefrontal cortex usually leads to the inability to plan or behave in a way that is socially acceptable. If childhood damage occurs, individuals may never develop any understanding of moral behavior. If an injury occurs in adulthood, a person can realize what is socially required, but can still behave in an acceptable way.
Prefrontal cortex damage is relatively common because this area is just behind the forehead. The function of this part of the cortex causes the organization and performing complex tasks. The judgments and decisions could be disturbed after its injury, because these are parts of the brain that allow one to consider possible future actions in the light of what has happened in the past, allowing the best course to be selected. Because disorders caused by damage are relatively specificKa and most of the brain can still function normally, the condition may not be recognized as brain damage at first.
The prefrontal cortex is involved in the ability to suppress speech and actions that would be considered immoral or inappropriate in most societies. For example, a person could not refrain from eating when hungry, even if it included removing food from someone else's plate. What is called working memory can also be affected by prefrontal bark damage. The working memory includes holding information for a few seconds, such as memorizing the phone number long enough to prevent the digits from preventing the phone.
When this part of the brain is damaged, the person usually shows a lack of empathy for other people; This is one of the factors involved in antisocial behavior involved. Some scientists have found that many violent criminals have defective prefrontal bark, with a reduction in the amount of mozko tissues in this area. Such findings are associated with behavior that includes dishonesty, lack of guilt and inability to see the situation from another point of view. Surgical treatment may be essential in cases of prefrontal cortex damage caused by tumors or bleeding in the brain. In many cases, no treatment is possible and people usually require supervision due to difficulty with organization and impulse control.
