Fig. 2

Illustration of the smoothing and interpolation procedure we have used to represent our response functions. Mean evoked spike rates are shown as a “bubble” plot, where the area of each circle is proportional to the firing rate (A), and the corresponding contour plot (B). C: same data after smoothing with a low-pass filter (2D Gaussian, σ = 0.66) and interpolation. We use this form of representation in subsequent figures, but analysis was done on the mean evoked counts as shown in A and B. D: spike shapes obtained at the start (red) and the end (black) of this recording. Recording took about 20 min. Percentage of spikes occurring within the refractory period (1.5 ms) is reported in the top left corner of the plot. This recording would be classed a single unit.
