Corpus callosum

Corpus callosum

Definition

Juliette Garnodier

The corpus callosum is the largest commissure in the brain, composed of white matter, linking the two hemispheres. It consists of a rostrum, a genu, a trunk, and a splenium. The fibers arising from the corpus callosum form the callosal radiations, which connect the various regions of the cerebral cortex.

This commissure exists only in Eutherian mammals and reaches its maximal development in primates.
