A comparison of EPSCs in central and peripheral calyces from intact crista slices. A: average of monophasic events from central zone (CZ) calyces (n = 4 cells, 468 events, black trace) and peripheral zone (PZ) calyces (n = 5 cells, 545 events, gray trace) recorded from crista slice preparations. B: EPSC frequency averaged 1.77 ± 0.15 Hz in CZ cells (n = 4) and 0.81 ± 0.15 Hz in PZ cells (n = 5); the difference between zones was statistically significant (*P = 0.003, t-test). C: the decay time for each cell EPSC average was fit with a single exponential, and mean values of 0.40 ± 0.11 for CZ calyces (n = 4) and 0.67 ± 0.16 for PZ calyces (n = 5) were obtained. There was no significant difference in decay tau between zones (P = 0.237, t-test).
