Anatomical and Clinical Review Most of the human brain cortex is association cortex. Functions of the association cortex

Anatomical and Clinical Review Most of the human brain cortex is association cortex. Functions of the association cortex have been more difficult to discover than those of any other brain areas. Association cortex is unimodal (modality specific) or heteromodal (higher order). Cerebral Cortex.
