Figure 10.

Relation of paired-pulse ratio to the fraction of resources used by a spike based on the phenomenological approach. A, Left, EPSCs induced in a CPn cell (top trace) by a train of presynaptic CPn cell spikes (bottom trace; 8 spikes at 10 Hz, followed by a spike at 500 ms later) and the simulated currents based on the phenomenological model (middle). Model parameter: U = 0.58; τD = 34.8 ms; τF = 702 ms. Paired-pulse ratio at 10 Hz = 1.1. Right, EPSCs induced in a CCS cell by a train of presynaptic CCS cell spikes and the simulated currents. Model parameter: U = 0.27; τD = 480 ms; τF = 2.8 ms. Paired-pulse ratio at 10 Hz = 0.75. B, Relation of paired-pulse ratio to parameter U corresponding to the release probability at the baseline level.
