Membrane properties of evoked DCN APs from conditioned P25–26 rats

Group	Vm, mV	Input resistance, MΩ	AP threshold, mV	Current required for evoked AP, nA	Latency, ms	Amplitude, mV	APD50, ms	APD50 rising, ms	APD50 falling, ms	AHP, mV	S1S2 interval, ms
PD	−46.53 ± 0.74	104.26 ± 9.89	−48.16 ± 1.13	0.09 ± 0.02	21.79 ± 5.34*	66.63 ± 2.06	0.82 ± 0.05	0.33 ± 0.02	0.50 ± 0.03	−8.87 ± 0.81†	17.46 ± 3.33
UP	−45.52 ± 0.72	82.22 ± 8.86	−47.39 ± 1.23	0.08 ± 0.01	46.46 ± 10.22	69.82 ± 2.10	0.73 ± 0.07	0.30 ± 0.02	0.43 ± 0.05	−12.30 ± 1.06	25.41 ± 8.09
Sit	−46.54 ± 0.93	99.69 ± 13.82	−45.87 ± 1.35	0.08 ± 0.02	39.83 ± 7.70	68.29 ± 2.89	0.74 ± 0.07	0.30 ± 0.03	0.44 ± 0.05	−12.73 ± 1.17	21.65 ± 4.77

Cell numbers (n) for the Paired (PD), Unpaired (UP), and Sit groups were 26, 20, and 16 cells, respectively. Fluorescent cell numbers (n) for the PD, UP, and Sit groups were 8, 7, and 5 cells, respectively. Note that there were group differences in AHP amplitude and a marginal group difference in latency for evoked AP. The difference in AHP amplitude was between the PD group and the UP and Sit groups. The difference in latency was between the PD and UP group.
