Summary statistics for response latencies and rise times. A: Latencies of LERG-RFs (yellow), pooled spike ON- and OFF-RFs, spike ON-RFs, and spike OFF-RFs (blue histograms with Gaussian fits, N = 18 LERG-RFs in two experiments, N = 53 spike-RFs in three experiments). Brown histograms of data restricted to local spike-RFs. B: Rise times for all spike-RFs (blue) and spike OFF-RFs (black). The upper plot shows pooled data for all three experiments. The lower plot shows data from the two experiments with stepwise response kinetics (experiments 142 and 033). Note here, that the rise times for spike OFF-responses are shorter than for spike ON-responses.
