A, spikelet number of spontaneous complex spikes is inversely related to latency from the preceding simple spike (r = –0.965, P = 0.002, n = 61 Purkinje cells). B, as in (A) but for evoked complex spikes (r
s = –0.829, P = 0.042, n = 27 Purkinje cells, Spearman's rank correlation). C, spikelet number for spontaneous complex spikes is inversely related to the latency from the preceding complex spike (r = –0.903, P = 0.014, n = 61 Purkinje cells), although no correlation exists between spikelet number and latency to the subsequent spontaneous complex spike (D, r = 0.381, P = 0.457, n = 61 Purkinje cells). Linear regression analysis and Spearman's rank correlation performed on complex spikes with one to six spikelets for (A) and (B), respectively. Data are expressed as the mean ± SEM.
