Quick Facts
The corpus callosum (aka great cerebral commissure) forms a white matter bridge between the left and right cerebral hemispheres of the brain, allowing communication between them.
The posterior portion of the corpus callosum is called the splenium and the anterior portion the genu, with the body of the corpus callosum lying between these two portions.
Communication between the cerebral hemispheres may sometimes be severed in cases of epilepsy by separating the corpus callosum.
