Increase background FR + control STS in a multipath DFP network without correlated background activity. Changes in network organization by rate increases and STS from the unconnected input neuron are mediated by multiple disynaptic feedforward pathways. Plot conventions are the same as in Figure 5. (A) Response of a multipath network between the disynaptically connected neuron I_2,1 and the output neuron to a step increase in background firing rate of the background processes onto output neuron O. To compensate for the increased native rate in O due to increased intranetwork connections, 64 background connections were eliminated. (B) DST distributions for the multipath during each phase of the rate-increase protocol. (C) Network response to STS from unconnected neuron I_0,1 to output neuron O in the multipath network. (D) DST distributions for the multipath network during the STS protocol.
