The brain and intelligence.
A measure of brain development is proposed which might correlate with intelligence. The neocortex/medulla volume is given for many species of primate, and it is found that this measure correlates with a measure of responsiveness to novel objects, and with performance on visual discrimination learning set. It is shown that cranial capacity/foramen magnum area is closely related to brain/medulla volume, and may therefore be used as a related measure with fossil species.
