Walsh & Hoyt: Cortical Area V2

In the human, area V2 is within the occipital lobe, adjacent to area V1. Area V2, the largest of the extrastriate visual areas, is the first region along the afferent visual pathway at which there is a convergence of input from the retina and pulvinar. Although these inputs terminate in different areas, the dense network of local interconnections in layer 2/3 may integrate them. Most retinocalcarine input to area V1 passes to area V2 before being distributed elsewhere. There is a further increase in cortical magnification from V1 to V2.
