Figure 8.

Response timing is more variable near pinwheel centers. (A) PSTH plots of responses to preferred orientation of individual orientation domain neurons (left; n = 55) and pinwheel center neurons (right; n = 31). (B) Plots of population variance in response amplitude as a function of time for each stimulus orientation. Pinwheel neurons are plotted in red and orientation domain neurons in blue. (C) PSTH plots of individual neurons, grouped as a function of laminar position and orientation map position. Orientation domain cells are plotted in the left column, and pinwheel center neurons in the right column. Superficial layer cells are plotted in blue in the top row, middle layer cells are plotted in red in the middle row and deep layer cells are plotted in green in the bottom row.
