Boundaries of topographically organized visual areas on the Visible Man cortex estimated using surface-based and stereotaxic projection methods. A, Boundaries between V2/V3 (top of map) and V2/VP (bottom of map) shown in green, relative to the most likely V1/V2 boundary transferred from Figure 9 and shown in black.Green contours represent boundaries estimated on the basis of distances along the cortical surface, taken from the summary cortical maps of DeYoe et al. (1996) and Sereno et al. (1995).Green dots and shading represent specific eccentricities along these borders, the Talairach coordinates of which were determined using the isocontour maps of DeYoe et al. (1996) and then projected to the cortical surface along with associated 10 mm uncertainty zones. B, Boundaries between V3/V3A (top) and VP/V4v (bottom), estimated using the same strategies as in A. C, The horizontal meridian representation of V3A (top) and of V4v (bottom), again using the same methods. The estimated extent of areas V1 (red), V2 (yellow), V3 and VP (blue-green), and lower-field V3A and upper-field V4 (purple) are displayed on a flat map (D), a lateral view (E), and a medial view (F).
