Figure 1: The Witelson criteria, which use a geometric partitioning of the human CC into seven regions in the midsagittal cross-sectional plane, are illustrated on a midsagittal MRI.[4],[5] A linear axis is drawn from the anterior-most to the posterior-most CC. Lines perpendicular to this axis divide the CC into seven segments: rostrum, genu, rostral body, anterior midbody, posterior midbody, isthmus, and splenium. CC: Corpus callosum, MRI: Magnetic resonance image
