Question

what would be the result if the corpus collosum was cut?
answers: a - d
a communication between a cerebral cortex in one hemisphere with other areas of the same hemisphere would be impaired.
b communication between the brain and spinal cord would be impaired.
c communication between the right and left cerebral hemispheres would be impaired.
d communication within a single brain hemisphere would be impaired.

Explanation:

The corpus callosum is a large bundle of nerve fibers that connects the two cerebral hemispheres. Its main function is to facilitate communication between the right and left hemispheres. If it is cut, this inter - hemispheric communication is disrupted. Option A is incorrect because the corpus callosum is not involved in communication within a single hemisphere. Option B is wrong as the corpus callosum has no role in communication between the brain and spinal cord. Option D is also incorrect for the same reason as option A; the corpus callosum is not related to intra - hemispheric communication.

Answer:

C. Communication between the right and left cerebral hemispheres would be impaired.
