Short-term depression reduces postsynaptic spiking correlations. Autocovariance (A), cross-covariance (B), and spike count correlation (C) for two postsynaptic spike trains produced by a population of correlated presynaptic neurons using a nondepressing, static synapse model. D, E, and F: same, but for a depressing synapse model. All plots are from Monte Carlo simulations. Firing rates of the neurons is approximately the same for both models (see methods), but short-term depression drastically reduces postsynaptic spiking correlations.
