Question

which of the following statements regarding the cerebral cortex is true? select one: a. the parts of the cerebral cortex that are responsible for vision, hearing, and other sensory information are mature by 6 months of age. b. the cerebral cortex is like a giant switchboard of fibers connecting the hemispheres and allowing them to share information and coordinate commands. c. the cerebral cortex primarily maintains balance and motor coordination. d. the parts of the cerebral cortex that govern mental associations and remembering are mature by 5 years of age.

Explanation:

The corpus - callosum is like a switchboard connecting hemispheres (not the cerebral cortex), the cerebellum maintains balance and motor - coordination, and the sensory areas of the cerebral cortex are not fully mature at 6 months. The parts of the cerebral cortex related to mental associations and memory do show significant development and approach maturity around 5 years of age.

Answer:

D. The parts of the cerebral cortex that govern mental associations and remembering are mature by 5 years of age.
