Fig. 2.
Cycle averages and spike histograms, as a function of stimulus orientation, for the simple cell in Figure1A. The first column refers to a blank stimulus, and the subsequent columns refer to 12 stimulus orientations, spanning the range between 0 and 360° in 30° steps. Responses are averaged over one stimulus cycle (0.25 sec).A, Firing rate. B, Membrane potential. Cell 61.
