What is the corpus callosum?

Human BodyBrain

Quick Answer

The corpus callosum is a thick bundle of nerve fibers connecting the brain’s left and right hemispheres. It allows information to pass between the two sides.

The Full Story

The corpus callosum is the largest white-matter structure in the brain. It is made of millions of axons that let the hemispheres communicate and coordinate tasks such as language, movement, and sensory processing. Without it, the two halves of the brain would be far less integrated. In some people, the corpus callosum is partially or completely absent from birth, a condition called agenesis of the corpus callosum. It is a key example of how the brain organizes communication internally.
