Extrastriate cortex

This term refers the region of the cortex of the mammalian brain located next to the striate cortex (also known as primary visual cortex). In Broca's system, the extrastriate cortex comprises areas 18 and 19, while the striate cortex comprises area 17.

In primates, the extrastriate cortex includes visual area V2, visual area V3, visual area V4, visual area MT (sometimes called V5), and visual area DP.

The extrastriate cortex is the locus of mid-level vision. Neurons in the extrastriate cortex generally respond to visual stimuli within their receptive fields. These responses are modulated by extraretinal effects, like attention, working memory, and reward expectation. --Sootymangabey 23:31, 10 Jun 2004 (UTC)
