Lying at the bottom of the cerebral longitudinal fissure, it is composed of more than 200 million transverse nerve fibers, and its primary function was discovered in the 1950s when experiments by Myers and Sperry indicated that, FTP, this thick band of white matter connects the two hemispheres of the brain.
Marsupials are distinguished by their lack of this structure, while in patients suffering from ADHD its bulk is slightly diminished.  The section curving forward from the genu into the frontal lobe is called the Forceps minor, while its underside forms the roof of the lateral ventricles.
