Corpus Callosum
The corpus callosum is a thick band of nerve fibers that is located at the center of the brain underneath the cerebrum and divides the brain into left and right hemispheres. It allows both sides of the brain to communicate by transferring sensory, cognitive, and motor information between the two hemispheres. The corpus callosum is also involved with eye movement and maintaining the balance of attention and arousal. It changes structurally throughout one’s life especially during childhood and adolescence.
