The arrangement of functional domains in (A) galagos, (B) squirrel monkeys, and (C) owl monkeys in PPCr, PMC, and M1. Matching domains are found in all three regions, where they are arranged in similar mediolateral sequences. No movement domains have been found in caudal PPC (PPCc). At least 3–4 domains (reach, grasp, defense and eye movements) are also present or likely in macaques (not shown, see text). Modified from
