The '''visual cortex''' is the area of the [[brain]] that performs higher-order sensory processing of [[visual perception|visual information]]. It is located in the [[occipital lobe]]. Sensory input originating from the [[eye]]s travels through the [[lateral geniculate nucleus]] in the [[thalamus]] and then reaches the visual cortex. The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1, ([[Brodmann area#BA17,V1|V1]]), [[Brodmann area]] 17<!---don't wikilink it as long as it redirects to here--->, or the '''striate cortex'''. The [[extrastriate cortex|extrastriate]] areas, or secondary visual cortex, consistconsists of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or [[Brodmann area 18]] and all [[Brodmann area 19]]).<ref>{{cite web | vauthors = Mather G |title=The Visual Cortex |url=http://www.lifesci.sussex.ac.uk/home/George_Mather/Linked%20Pages/Physiol/Cortex.html |publisher=School of Life Sciences: University of Sussex |access-date=6 March 2017 |language=en}}</ref>

Both [[cerebral hemisphere|hemispheres of the brain]] include a visual cortex; the visual cortex in the left hemisphere receives signals from the right [[visual field]], and the visual cortex in the right hemisphere receives signals from the left visual field.
