Figure 2.

Group‐constrained RCSE. RCSE time courses calculated from responses to high contrast (95%) stimuli for eight subjects are shown in blue (V1), green (V2), or red (V3), with group‐RCSE solutions superimposed in black. A: RCSE solutions with 36 stimulus locations. B: RCSE with 4 stimulus locations. Locations of the 4 stimuli were at 5.3° visual angle and 45° from the horizontal and vertical meridians, as indicated by the inset image of stimulus locations.
