a PRF centers are used to compute a series of masks that are used to define wedge-ROIs in the visual field. b The wedge-ROI masks are overlaid on the cortical surface. The mean surface area is computed for each wedge-ROI. This is repeated for each wedge-ROI width (15°–55°). As expected, the colored wedge-ROIs become larger as wedge-width increases. Black lines represent the dorsal and ventral borders of V1/V2. Each sphere is the native surface that has been transformed to a flattened sphere with the occipital pole aligned to the center.
