Figure 5.

Threshold dependence of the correlation between the adjacency matrix and the co-activation matrix [(A)-lower panel, in blue] for a modular graph; same for the co-activation matrix with time delay ±1 [(B)-lower panel, in blue]. The value of the average correlation coefficient (±the standard deviation) of binary random sequences is plotted in red. Connection density of the co-activation matrix [(A)-top panel, in green] as a function of the threshold, and the similar graph for the co-activation with time delay ±1 [(B)-top panel, in green].
