Function: The corpus callosum transfers motor, sensory, and cognitive information between the brain hemispheres.

Location: A thick band of nerve fibers that divides the cerebrum into left and right hemispheres. It connects the left and right sides of the brain allowing for communication between both hemisphere.

No longer worked properly: Will be unable to vocally name what he or she has seen. This is because the speech-control center is in the left side of the brain in most people, and the image from the left visual field is sent only to the right side of the brain (those with the speech control center in the right side will experience similar symptoms when an image is presented in the right visual field). Since communication between the two sides of the brain is inhibited, the patient cannot name what the right side of the brain is seeing. The person can, however, pick up and show recognition of an object (one within the left overall visual field) with their left hand, since that hand is controlled by the right side of the brain.

Facts: fact 1-The cerebral hemispheres are separated by a deep groove, the longitudinal cerebral fissure. At the base of this fissure lies a thick bundle of nerve fibres.
fact 2-The term 'corpus callosum' means tough body in Latin.
fact 3-With approximately 200-250 million contralateral axonal projections to its credit, corpus callosum is the largest among the various white matter structures in the central nervous system.
