The prefrontal cortex in the left hemisphere is involved with verbal memory while the prefrontal cortex in the right hemisphere is involved in spatial memory. The left frontal operculum region of the prefrontal cortex, or Broca's area , is responsible for expressive language, i.e. language production.
Hypofrontality is a symptom of numerous neurological diseases defined as reduced utilization of glucose and blood flow in the prefrontal cortex. Hypofrontality can be difficult to detect under resting conditions, but under cognitive challenges, it has been seen to correlate with memory deficits along with executive function deficits.
In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
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 ...
Dysexecutive syndrome (DES) consists of a group of symptoms, [1] usually resulting from brain damage, that fall into cognitive, behavioural and emotional categories and tend to occur together. The term was introduced by Alan Baddeley [ 2 ] [ 3 ] to describe a common pattern of dysfunction in executive functions , such as planning, abstract ...
Children with TS are found to have a larger prefrontal cortex, which may be the result of an adaptation to help regulate tics. [77] It is likely that tics decrease with age as the capacity of the frontal cortex increases. [77] Cortico-basal ganglia (CBG) circuits may also be impaired, contributing to "sensory, limbic and executive" features. [14]
Like directed attention fatigue, ADHD involves the prefrontal cortex. Specifically, the right prefrontal cortex is less active among children with ADHD. Experimentation has shown that the severity of ADHD symptoms can be correlated to the degree of asymmetry between blood flow in the left and right prefrontal cortex.
The anterior superior frontal lobe is known as the prefrontal cortex which is responsible for the initiation and ideation of verbal speech. [7] The damage leaves the major language networks, Broca's and Wernicke’s areas and the arcuate fasiculus , unaffected. [ 1 ]
