Quizplus · Accepted Answer

A person with a severed corpus callosum will experience a disconnection between the two hemispheres of the brain, but this does not necessarily mean that they will lose the ability to speak or feel objects. The corpus callosum mainly facilitates communication between the two hemispheres, so its severance may affect tasks that require coordination between both sides of the brain, such as reaching for objects with both hands simultaneously. However, abilities controlled by a specific hemisphere, such as language processing in Broca's area (typically located in the left hemisphere) or somatosensation in the parietal lobe (which receives sensory information from the opposite side of the body), should still be intact.
