It spans part of the longitudinal fissure, connects the left and right cerebral hemispheres, and enables communication between the hemispheres . It is the largest white matter structure in the human brain, consisting of 200--250 million axonal projections . </P> <P> The posterior end of the corpus callosum, near to the cerebellum, is called the splenium . This is the thickest part, and overlaps the tela chorioidea of the third ventricle and the mid-brain, and ends in a thick, convex, free border . Splenium translates as bandage in Greek . A sagittal section of the brain shows that the posterior end of the corpus callosum is acutely bent forward, the upper and lower parts being applied to each other . </P>
