(A1) The average number of neurons spiking at the time-step in the sub-networks , 2, and 3 are shown red, blue, and green, respectively, for avalanches of duration starting from the sub-network 1. (B1) The same as (A1) for the mean spiking time . (A2) Cumulated temporal profiles for avalanches of durations . (B2) The same as (B1) for avalanches of durations . (A3) and (B3) are the same as (A2) and (B2), respectively, after rescaling the axes ().
