Also shown are the insular cortex (purple), the brain stem (black), and the cerebellum (blue). The frontal lobe of the human brain is both relatively large in mass and less restricted in movement than the posterior portion of the brain. [1] It is a component of the cerebral system, which supports goal directed behavior. [2]
Dorsolateral prefrontal cortex. This area is associated with the impairment of the cognitive abilities that control and regulate behavior and long-term memory formation (especially relating to procedural sequence memory) when either brain damage or a lesion is present. [13] Orbitofrontal cortex
The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...
Damage to the prefrontal cortex will cause a breakdown in this system, resulting in utilization behaviors. [28] These behaviors would include spontaneous sequences of action on irrelevant objects in the surroundings with no clear goal in mind. [28] This theory has helped to extend the current knowledge on executive functions.
The prefrontal cortex is involved with mental functions including; affective range of emotions, forethought, and self-control. [92] 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 ...
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]
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 ...
Lack of impulse control in children may be attributable to the fact that the prefrontal cortex develops slowly. [56]: 406 Todd A. Hare et al. use functional MRI techniques to show that the ventromedial prefrontal cortex (vmPFC) and the dorsolateral prefrontal cortex (DLPFC) are crucial to the exertion of self-control. They found the vmPFC ...
