Which brain structure is responsible for coordinating communication between the left and right hemispheres?

• A. Cerebellum
• B. Hippocampus
• C. Corpus Callosum
• D. Amygdala

Answer: (C)

The main idea is interhemispheric communication, which is handled by a central bridge of nerve fibers that connects the two halves of the brain. This structure, a thick bundle linking corresponding areas of the left and right hemispheres, allows information to pass back and forth quickly. That cross-talk is essential for coordinated perception, movement, and thinking, since each side can share its processing with the other. Other structures have different roles: the cerebellum mainly coordinates movement and balance; the hippocampus is crucial for forming new memories; and the amygdala processes emotions like fear. So while those areas are important, the bundle that enables communication between the hemispheres is the corpus callosum.
