Answer Choices:
Communication between the right and left cerebral hemispheres would be impaired.
⮞ The corpus callosum is a large bundle of nerve fibers that connects the right and left cerebral hemispheres.
⮞ Cutting it, a procedure sometimes done for severe epilepsy (callosotomy), prevents the two hemispheres from sharing information.
⮞ Each hemisphere can still function independently, but cross-hemispheric communication is disrupted.
⮞ This can cause unique deficits such as the inability to verbally describe an object placed in the left hand (since language is typically left-hemisphere dominant).
⮞ Communication within each hemisphere or between the brain and spinal cord remains intact because those pathways do not rely on the corpus callosum.
