Spike time correlations and timescales of correlations. (a) Averaged CCGs for all SU/MU pairs recorded for the ambiguous cylinder (purple), the unambiguous cylinder (grey) and the random motion (green) stimuli. Only sites were included that showed matching and strong SU and MU tuning (see Methods) (n = 24). CCGs were smoothed with a Gaussian kernel (10 ms s.d.). (b) Average rCCG plotted as a function of the time-lag (τ), i.e. the integration window, for the ambiguous cylinder (purple), the unambiguous cylinder (grey) and the random motion (green) stimuli. Horizontal black and red lines indicate a significant difference between the purple and green and the purple and grey line, respectively (p < 0.01, cluster based permutation test, n = 24). Horizontal dashed lines indicate the corresponding average rSC values. rCCG courses start off at values below zero, because at time-lag zero there are no coincident spikes due isolating the SU from the MU activity on the same electrode. Error bars indicate the s.e.m.
