What structure connects the two cerebral hemispheres and allows communication between them?

• A. Thalamus
• B. Hypothalamus
• C. Corpus callosum
• D. Cerebellum

Answer: (C)

Interhemispheric communication is achieved by a large bundle of nerve fibers that links corresponding areas across the brain’s midline, allowing information to move between the two sides. This white-matter structure is the corpus callosum, the widest and most prominent pathway connecting the hemispheres and coordinating activities that require both sides. By comparison, the thalamus mainly relays sensory signals to the cortex, the hypothalamus regulates hormones and basic drives, and the cerebellum coordinates movement and balance. The corpus callosum’s specific job is to enable communication between the hemispheres, supporting integrated processing across both sides of the brain.
