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 ...
The prefrontal cortex, the most anterior region of the brain, comprises several key areas that are particularly important for higher mental functions that control various aspects of human personality including anticipation and planning, initiative/judgement, memory and the control of decision making.

Diffuse injury has more microscopic injury than macroscopic injury and is difficult to detect with CT and MRI, but its presence can be inferred when small bleeds are visible in the corpus callosum or the cerebral cortex. [34] MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time ...
The progression of the degeneration caused by bvFTD may follow a predictable course. The degeneration begins in the orbitofrontal cortex and medial aspects such as ventromedial prefrontal cortex. In later stages, it gradually expands its area to the dorsolateral prefrontal cortex and the temporal lobe. [52]
Spinal cord injury results in the damage of the axonal tracts whose function is to control motor and sensory activity. This protein has been found in this axonal tracts of adolescent rat spinal cords following injury. Furthermore, a five time increase in Lingo-1 mRNA levels was detected 14 days post injury.

Testing with median nerve SEPs is used to identify the sensory and motor cortex during craniotomies and in monitoring surgery at the midcervical or upper cervical levels. Posterior tibial nerve SEP monitoring is widely used for monitoring the spinal cord during scoliosis procedures and other surgical interventions in which the spinal cord is at ...
Another key region is the anterior temporal cortex (ATC) in the posterior region. In adults, the left ATC showed greater response than the same region in adolescents when tested on emotional tests of mentalising. Finally, the medial prefrontal cortex (MPFC) and the anterior dorsal MPFC (dMPFC) are activated when the mind is stimulated by ...
