Fig. 9.
The anatomical relationship of V3A and a sulcal landmark. This figure is based on the same data as in Figure 8, but it is rendered on inflated rather than folded cortical surfaces. Only the boundaries of V3A have been drawn (solid white lines) so that the underlying sulcal/gyral topography can be seen. In each hemisphere the fundus of the transverse occipital sulcus has been indicated with dotted white lines. In all cases examined, the peripheral visual field representation of V3A (superior in cortex, toward the top in the figure) extends into the transverse occipital sulcus, typically at a locally near-orthogonal angle. The calibration bar is accurate, excepting perspective foreshortening.
