Effects of gNa on AP probability and timing in response to evoked synaptic activity. A, Representative experiment. Top traces represent responses of BC to trains of fiber stimulation at 200 Hz. Stimulus artifacts are removed for clarity. Bottom raster plots represent timing of APs from 5 similar trials. B–D. Average measurements from 6 BCs showing effect of gNa on (B) AP probability, (C) AP latency, and (D) SD of AP latency (jitter). E–G, Changes in AP probability (E), latency (F), and jitter (G) with respect to control (0 μS gNa). *p < 0.05.
