Coronal sections through the brain of an autistic patient. The overlay denotes those cortical areas showing abnormalities of cortical thickness. Towards both pole regions cortical thickness abnormalities preferentially affected the crest of gyri. Defects in cortical width tended to affect both crest and sulci of gyri in middle sections. Defects affecting crest of gyri were usually larger than those seen at the sulci of gyri. The y-coordinates are the normalized positions as in Figures 3 and 4.
