Before the hemispheres of the cerebral cortex lateralize,
A) damage to a particular region means that the abilities it normally controls are lost forever.
B) other parts can take over the tasks that would have been handled by a damaged region.
C) each hemisphere controls only one side of the body.
D) each hemisphere receives sensory information from only one side of the body.

Question

Quizplus · Accepted Answer

Before lateralization, the brain has more plasticity and flexibility, meaning that if a region is damaged, other parts of the brain may be able to take over the tasks that were initially handled by the damaged region. This is known as brain plasticity or neuroplasticity. Therefore, option B is the best choice. Option A is incorrect because brain plasticity allows for some recovery of lost abilities. Option C and D are also incorrect because both hemispheres receive sensory information from both sides of the body, and both hemispheres are involved in controlling movement and processing cognitive functions.
