Fig. 8.

Deterministic and static probabilistic synapse models transfer correlations differently than a stochastic, depressing synapse model. Pearson correlation between a pair of conductances produced by the spike trains in Fig. 3, A–C, using the depressing synapse model described in methods (solid line, same as Fig. 3I), using a model with a constant vesicle release probability (dotted line), and using a depressing synapse model with deterministic dynamics (dashed line). Parameters were chosen so that all models produce the same mean conductance.
