Figure A1.

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