Band of white matter connecting the cerebral hemispheres and involved in learning and memory is which structure?

• A. Corpus Callosum
• B. Frontal Lobe
• C. Cerebellum
• D. Thalamus

Answer: (A)

Interhemispheric communication relies on a large band of myelinated fibers that connects the two cerebral hemispheres. This structure, the corpus callosum, is the primary bridge for information exchange between the left and right sides of the brain. Because learning and memory require integrating information processed in both hemispheres and coordinating widespread neural networks, the corpus callosum supports these processes by enabling rapid, synchronized activity across regions. The other structures aren’t designed as this interhemispheric connector: the frontal lobe is a gray-matter region involved in executive functions, the cerebellum coordinates movement and some motor learning, and the thalamus acts mainly as a relay center for sensory and motor signals. So the band of white matter linking the hemispheres is the corpus callosum.
