Which structure is a major bundle of nerve fibers that facilitates communication between the two cerebral hemispheres?

Explanation

The corpus callosum is a large collection of axons that connects the left and right cerebral hemispheres, enabling them to communicate. The cerebral cortex is the brain's outer layer involved in complex functions, the pons is part of the brainstem involved in motor control, the amygdala processes emotions, and the thalamus acts as a relay station for sensory information.
