Witelson Subregion Segmentation. Notes. Segmentation using the Witelson [1989] approach was performed automatically by placing five perpendicular lines across the maximum length of the CC at 1/5, 1/3, and 1/2 the distance from the outer limits of the genu and splenium. Subregion 1 (W1, red) corresponds to the rostrum, W2 (orange) corresponds to the genu, W3 (yellow) corresponds to the rostral body, W4 (green) corresponds to the anterior midbody, W5 (blue) corresponds to the posterior midbody, W6 (purple) corresponds to the isthmus, and W7 (lavender) corresponds to the splenium.
