The transverse fibres of the corpus callosum, as they enter the white medullary centre of the cerebral hemisphere, separate from each other so as to reach most parts of the cerebral cortex. These diverging fibres are termed the radiatio corporis Genu Cingulum Frontal fibres Cut surface Fibres of corona radiata Intersection of callosal and corona radiata systems fibres Corpus callosum Cingulum (cut).

The more anterior of the fibres which compose the genu of the corpus callosum sweep forwards in a series of curves into the anterior frontal region of the hemisphere. A large part of the splenium, forming a solid bundle termed the occipital part of the radiation of the corpus callosum ( forceps major), bends suddenly and abruptly backwards into the occipital lobe (Fig. 559).
