corpus callosum. a great band of deeply situated transverse white fibers uniting the two halves of the cerebrum in humans and other mammals.
This gives the corpus callosum a white appearance in unstained sections, and in the cell-stained sections in this atlas. It forms part of the white matter of the brain. In the fiber-stained sections in this atlas, myelin is stained a blue-black color, so the corpus callosum appears black. About one-third of the information traveling to a cerebral hemisphere comes from the corpus callosum (that is to say, it comes from the contralateral hemisphere).
