To determine the locus, extent and topograhic organization of cortical
projections of area V2, we injected tritiated amino acids under
electrophysiological control into 15 V2 sites in 14 macaques. The injection
sites included the foveal representation and representations ranging from
central to far peripheral eccentricities in both the upper and lower visual
fields. The results indicated that all V2 sites project topographically
back to V1 and forward to V3, V4 and MT. There is also a topographically
organized projection from V2 to V4t, but this projection is limited to the
lower visual field representation. V2 thus appears to project to virtually
all the visual cortex within the occipital lobe. In addition to these
projections to occipital visual areas, V2 sites representing eccentricities
of approximately 30 degrees and greater project to three visual areas in
parietal cortex-the medial superior temporal (MST), parieto-occipital (PO)
and ventral intraparietal (VIP) areas. This peripheral field representation
of V2 also projects to area VTF, a visual area located in area TF on the
posterior parahippocampal gyrus. Projections from the peripheral field
representation of V2 of parietal areas could provide a direct route for
rapid activation of circuits serving spatial vision and spatial attention.
