Figure 4.

Temporal differences between UV and green responses. A, B, Scatter plots (top) of peak latency for bright and dark stimuli similar to Figure 2B but plotted separately for green (A) and UV (B) luminance changes. The resulting classification is shown below for each color. C, Scatter plot of the difference between green and UV latency for each cell's correct sign luminance change (bright ON, dark OFF). D, Histogram of latency differences (green minus UV) for ON (white bars) and OFF (black bars).
