Single spike information rate I_spike (relative to RGC information rate) varies with stimulus size. For all the X Off cells, we group the results according to stimulus size. For a given group, we compute the average over all the measurements. Error bars are ±1 SD. Stimulus sizes are given here (upper right of each panel) in multiples of RF center diameter (see Materials and Methods). ON cells were omitted because we did not have enough reliable data from these cells to include them in this summary.
