Question

Quizplus · Accepted Answer

Lesions restricted to structures in one half of the brain (hemispheric lesions) typically have less severe effects than do bilateral lesions, which affect both brain hemispheres. This is because the brain is capable of compensating for the loss of function in one hemisphere by relying on the intact hemisphere, a phenomenon called brain plasticity. Unilateral lesions (A) and bipolar lesions (B) are not commonly used terms in neuroscience. Cryogenic lesions (C) involve freezing tissue and are not typically used in brain lesion studies. Aspiration lesions (D) involve removing tissue by suction and are not commonly used in experimental research.
