BlackTom AI · Accepted Answer

This question asks about the structure that enables communication between the brain’s two hemispheres.
Option 1: 'Sympathetic nervous system' is part of the autonomic nervous system that typically prepares the body for ‘fight or flight’ responses and does not mediate interhemispheric communication. It operates diffusely, not as a bridge between hemispheres.
Option 2: 'Parasympathetic nervous system' is the counterpart to the sympathetic system, promoting ‘rest and digest’ activities. Like the sympathetic system, it modulates bodily functions but does not connect the two cerebral hemispheres.
Option 3: 'Corpus callosum' is a large bundle of nerve fibers that directly connects the left and right hemispheres, allowing them to share information and coordinate activities. This is the key structure responsible for interhemispheric communication.
Option 4: 'Vagus nerve' is a major component of the parasympathetic system that extends from the brainstem to various organs, influencing heart rate and digestion, but it does not serve as a bridge between the cerebral hemispheres.
In summary, the correct functional role here is fulfilled by the corpus callosum, which physically links both hemispheres and enables cross-hemisphere signaling, whereas the other options describe systems involved in autonomic regulation or peripheral signaling rather than interhemispheric communication.
