The corpus callosum connects the two halves of the brain at the bottom of its structure and delivers visual, auditory, and somatosensory messages between each half. Here, billions of neurons and glia can be found working together to send messages that form what is known as the cerebral cortex. The corpus callosum is responsible for eye movement and visual perception, maintaining a balance between arousal and attention, and the ability to identify locations of sensory stimulation. In a clinical setting, those with epilepsy may benefit from the division of the corpus callosum.
