Abstract:

Primates and other mammals have at least three visual areas in common, V1, V2, and prostriata, as well as one or more subdivisions of visual temporal cortex. V1 of primates differs from other mammals in laminar and modular organization, and V2 has a modular organization that is unique to primates. Other areas, such as V3 and MT, appear to have emerged with the evolution of the first primates. Those areas and other extrastriate areas may have been modified or differentiated from areas in the nonprimate ancestor of primates. However, all primates have more visual areas than their nonprimate ancestors. Old World macaque monkeys have more visual areas than prosimian primates, and more areas have been identified in humans than in macaques.
