Question

Quizplus · Accepted Answer

Split-brain surgery severs the corpus callosum, which is the bundle of nerves connecting the left and right hemispheres of the brain. This means that information presented to one side of the body cannot be transferred to the other side. As a result, if an object is placed unseen in the left hand of a person who has had split-brain surgery, the right hemisphere of the brain (which controls the left hand) will be aware of the object, but the left hemisphere (which controls language and verbal communication) will be unaware of it. Therefore, the person will not be able to describe it.
