Extrastriate

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 terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann 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.
