Which of the following generalizations does not describe the cerebral cortex?

a. each hemisphere is chiefly concerned with sensory and motor functions of the contralateral side of the body.
b. the hemispheres are exactly equal in function.
c. no functional area of the cortex works alone.
d. the cerebral cortex contains three kinds of functional areas.

The hemispheres are exactly equal in function is the generalization that does not describe the cerebral cortex.

The cerebral cortex is an area found in the outer part of the brain and the purpose of which is to divide this structure into two hemispheres, and into different specialized areas, through multiple folds and convolutions.

Therefore, we can conclude that the hemispheres are exactly equal in function is the generalization that does not describe the cerebral cortex.

option D - The cerebral cortex contains three kinds of functional areas.

Explanation:

The cerebral cortex contains FOUR (not three) kinds of functional areas. They are the Frontal, Temporal, Pariental and Occipital lobes.

Do note that all the other generalizations rightly describe the cerebral cortex except OPTION D
