Group‐constrained RCSE after nonlinear optimization. RSCE time courses calculated from responses to high contrast (95%) stimuli at 36 locations for eight subjects after three methods of nonlinear optimization shown in blue (V1), green (V2), or red (V3), with recalculated group‐RCSE solutions superimposed in black. A: Neighborhood search. B: Displacement search without prior. C: Displacement search constrained by group‐RCSE prior.
