1-33 (red) Section A Rostrum, Genu, Rostral body (regions 1, 2, 3) Prefrontal, premotor, supplementary motor
34-50 (green) Section B Anterior mid-body (region 4) Primary motor
51-67 (blue) Section C Posterior mid-body (region 5) Somesthetic, posterior parietal
68-81 (purple) Section D Isthmus (region 6) Superior temporal, posterior parietal
82-100 (yellow) Section E Splenium (region 7) Inferior temporal and occipital

Correspondence between the 100 callosal points clustered in five sections (from A to E), as were used in the present work, compared to the “classical” Witelson's subdivions, according to interhemispheric connected cortical areas.
