Brodmann demonstrated that the primary visual cortex (i.e., area 17) receiving the input from the LGN is located in the posterior part of the occipital lobe in a number of species. This area is now usually called V1 (visual area 1) or the striate cortex, after the striae of Gennari. In contrast, all other visual areas in the cortex lacking the stria (which is a myelinated stripe where the LGN axons enter the gray matter of the V1) are termed extrastriate.

V1 has been mapped in several species. In the cat, it occupies the posteromedial portion of the cortex, extending from the crown of the lateral gyrus on the dorsal surface to the superior bank of the splenial sulcus on the medial surface. In the dog, it is located at the junction of the marginal and endomarginal gyri. The striate cortex has also been identified in the horse.
