Relative neocortex (part of the brain involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, conscious thought, and in humans, language). size is correlated with mean group size among primates. A primate species with a greater group size on the average has a larger neocortex relative to the rest of the brain.
