Question

multiple choice question a brain in which the ______ has been cut, limiting the communication between the two hemispheres is called a split brain. corpus callosum parietal lobe cerebellum brainstem

Explanation:

To determine the correct answer, we analyze the function of each brain structure:

• The corpus callosum is a thick band of nerve fibers that connects the two cerebral hemispheres and facilitates communication between them. Cutting the corpus callosum limits this communication, resulting in a "split brain."
• The parietal lobe is involved in sensory processing and spatial awareness, not interhemispheric communication.
• The cerebellum is responsible for coordination and balance, not connecting the hemispheres.
• The brainstem controls basic life functions (e.g., breathing, heart rate) and is not involved in interhemispheric communication.

Only the corpus callosum fits the description of a structure whose cutting limits communication between the two hemispheres.

Answer:

A. corpus callosum
