Short Term Synaptic Depression Imposes a Frequency Dependent Filter on Synaptic Information Transfer

Figure 5

Coherence between a single presynaptic spike train and the postsynaptic conductance it induces.

The coherence, , between a Poisson presynaptic spike train, , and the resulting postsynaptic conductance, . The stochastic model (solid blue) yields a high pass coherence that is dramatically smaller than the flat coherence predicted by the deterministic model (dashed red).
