Figure 5

Time-course of spike count correlations. Average rSC time-courses estimated from a sliding 100 ms window. Purple, grey and green lines show the average rSC time-courses for the ambiguous cylinder, the unambiguous cylinder and random motion, respectively. Averages were computed over all sites recorded under all three stimulus conditions (n = 24). The black horizontal bar indicates a time window with a significant difference between the ambiguous cylinder and the random motion condition (p < 0.01; cluster based permutation test). The red horizontal bar indicates a significant difference between ambiguous and unambiguous cylinder conditions (p = 0.01). Time-courses were smoothed with a 30 ms (s.d.) Gaussian kernel for display. All statistics were performed on the un-smoothed traces.
