(A) A function was fit between the C1 input and the simulated broadband output (black line). Inverting this function allows us to take the measured electrocorticographic (ECoG) broadband values (green arrows to dots colored by stimulus condition) and convert these into estimates of the C1 input levels (orange arrows). Because the simulations contain noise, the predicted broadband need not match the measured broadband exactly; however, the agreement is close, as shown in S9 Fig. The parameters for C2 and C3 were fit similarly. (B) The C1, C2, and C3 parameters for the simulation of responses in a V2 electrode for 9 stimuli (8 contrast patterns plus a blank condition). These parameter fits were made using the full ECoG dataset (for this electrode), so there are no error bars on the input parameters.
