Figure 2.
Properties of unitary EPSPs in a single connection. A, Presynaptic AP and overlay of 10 successive postsynaptic EPSPs from the pair shown in Figure 1. B, EPSP unitary amplitude histogram for this connection. White, noise; gray, sweeps including failures. C, AP-to-EPSP onset latency histogram. Note the narrow distribution (Gaussian fit with full width at half-maximum of 0.2 ms). D, Relationship between EPSP amplitudes and AP-EPSP latency in the single connection. There was no significant correlation.
