Midsagittal schematic of the CC, showing Witelson scheme (top) and Hofer and Frahm scheme (bottom). Witelson scheme: I, premotor; II, motor; III, somesthetic; IV, parietal/temporal; V, temporal/occipital. Hofer and Frahm scheme: I, prefrontal; II, premotor; III, motor; IV, sensory; V, parietal/occipital/temporal. Note the posterior shift in the location of the primary motor segment from Witelson segment II to Hofer and Frahm segment III.
