Right skewed PRC gives rise to leader-follower locking mode. A1, A2). Time lags indicate the time from spiking of one neuron to that of the other neuron and vice-versa. Only anti-phase and synchronous modes were observed with original Wang-Buzsaki (WB) model in which PRC is left skewed. B1, B2). Leader-follower mode is approached when original WB PRC is skewed toward the right. C1, C2). The leader-follower mode is more closely approximated as the PRC is further right skewed. A negative value for resetting indicates an advance in our convention.
