Figure 4.

a, Dynamics of adaptation, averaged over all single units (n = 22). Spike probability is plotted for 50 ms windows, smoothed with a boxcar filter of width = 10 ms (resolution: 1 ms). PSTHs are aligned to onset of each consecutive pulse. Left, Four pulses at 10 Hz; right, four pulses at 20 Hz. Black dotted line in both panels denotes four pulses at 100 Hz; here, the response to individual pulses could not be disentangled. b, Adaptation index (AI), computed separately for maximum spike probability and spike count, shown for both stimuli. c, d, same as a, b, but for multi units (n = 160).
