Definition: the region of the cerebral cortex occupying the entire surface of the occipital lobe, and composed of Brodmann areas 17–19. Brodmann area 17 (which is also called striate cortex or area because the line of Gennari is grossly visible on its surface) is the primary visual cortex, receiving the visual radiation from the lateral geniculate body of the thalamus. The surrounding Brodmann areas 18 (parastriate cortex or area) and 19 (peristriate cortex or area) are probably involved in subsequent steps of visual information processing; Brodmann area 18 is referred to as the secondary visual cortex.
Synonym(s): visual area
