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

Figure 7

Linear information transfer rate as a function of signal frequency.

The linear mutual information rate, , between a rate-coded signal, , and the total conductance, , produced by (A) , (B) n = 100, and (C) presynaptic spike trains, each encoding . The information rate is plotted as a function of the central frequency, , at which is encoded. The stochastic model (solid blue) transmits quickly varying signals more reliable than slowly varying signals. The deterministic model (dashed red) transmits information encoded at any frequency equally well.
