Architecture of the network model. Two networks are coupled with an inhibitory/excitatory reciprocal connection. Excitatory connections are shown as black pointed arrows, inhibitory connections as blue rounded arrows. The synfire chain network (SFCN) consists of 10 synfire chains connected into a directed graph as shown in Fig. 4. The backward-and-forward connected network (BFCN) consists of a single backward-and-forward connected chain. Both networks are driven by an independent excitatory Poisson input to each neuron with rate ν _x = 7.7 kHz
