Lesions of the Prefrontal Cortex Essay -- Neurology Health Medical Ess

Lesions of the Prefrontal Cortex The anterior cortex is involved in a wide variety of functions. It is known as the bea of the brain which has executive director control, taking input from other areas of the brain and combining and applying those functions (Kalat 2004). Lesions to the prefrontal area can greatly impair overt behavior of an inflicted individual. These deficits are dependent upon the severity of the lesion and the specific region of the prefrontal cortex in which the lesion resides (ventrolateral, dorsolateral, orbitofrontal, and anterior prefrontal)(Eslinger 2003).
