STS in an aDFP network with uncorrelated background activity. Monosynaptic and disynaptic STS in a feedforward network with uncorrelated background activity. Plot conventions are the identical to those in Figure 5. (A) Network response to STS from the monosynaptically connected neuron I_1,1 to the output neuron O. A substantial increase in the synaptic weight flanked by the STS protocol was observed. (B) DST distributions during each phase of the STS protocol. An increase in probability of short-lag DSTs was observed. (C) Network response to STS from the disynaptically connected neuron I_2,1 to the output neuron O. Synaptic weights terminating on the output neuron declined considerably. (D) DST probability distributions before, during, and after monosynaptic STS, as well as under control conditions where no stimulation occurred. A transient increase in short-lag DSTs was observed between the disynaptically connected neurons peri-stimulation, but this change disappeared post-stimulation.
