Splenial fibers in the macaque traced using autoradiography. Lateral (Left) and medial (Right) views of a left hemisphere are shown. The black blobs on the cortical surface indicate the tracer injection zones, and the dots in the corpus callosum (CC) indicate the labeled splenial fibers. These “area 19” injections appear to be primarily in dorsal visual areas, including dorsal V3 and quite likely V3A. Compare the labeled splenial region in macaque to the splenial map of the dorsal area projections in human (Fig. 4). (Modified from figure 1C of ref. 1.)
