The Wisconsin Card Sorting Test (WCST) can be used in conjunction with other tests to speculate to possible dysfunction of the prefrontal cortex, the front-most area of the frontal lobe, that plays an important role in executive functioning. However, since the age of modern medicine and brain imaging, the WCST has been purported to be ...
Somatic markers are probably stored in the ventromedial prefrontal cortex (highlighted). The somatic marker hypothesis, formulated by Antonio Damasio and associated researchers, proposes that emotional processes guide (or bias) behavior, particularly decision-making. [1] [2]
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
The weakness of these tests is that they do not necessarily show dysfunction of the orbitofrontal cortex. [ citation needed ] In order to solve this problem, some researchers have combined neuropsychological tests which detect the dysfunction of orbitofrontal cortex into one grouping, so that it increases its specificity to the degeneration of ...
The most frequent cause of the syndrome is brain damage to the frontal lobe. Brain damage leading to the dysexecutive pattern of symptoms can result from physical trauma such as a blow to the head or a stroke [6] or other internal trauma. It is important to note that frontal lobe damage is not the only cause of the syndrome.
Neurotoxins can be used to selectively damage very specific nerve tracts in the brain. [30] [31] [32] Pertaining to the study of memory, areas of interest include the hippocampus, the rhinal cortex, the pre-frontal cortex, and the frontal cortex. The neurotoxic lesion technique uses neurotoxins such as ibotenic acid to selectively disrupt or ...
The prefrontal cortex is involved with mental functions including; affective range of emotions, forethought, and self-control. [93] Moreover, there is a scarcity of mental control displayed by individuals with a dysfunction in this area over their behavior, reduced flexibility and self-control and their difficulty to conceive behavioral ...
