Summary of membrane properties of evoked DCN RDs from conditioned P25–26 rats

Group	RD threshold, mV	Current required for evoked RD, nA	Latency, ms	RD amplitude, mV	RD APD50, ms	RD APD50 rising, ms	RD APD50 falling, ms	RD AHP, mV	RD S1S2, interval, ms
PD	−54.50 ± 1.20*	−0.71 ± 0.11	48.89 ± 12.78*	69.34 ± 2.40	0.85 ± 0.07	0.33 ± 0.02	0.52 ± 0.04	−9.43 ± 1.13*	14.08 ± 2.66
UP	−47.89 ± 1.18	−0.89 ± 0.16	111.97 ± 22.19	68.64 ± 2.21	0.76 ± 0.08	0.30 ± 0.03	0.46 ± 0.05	−13.25 ± 1.41	21.67 ± 5.21
Sit	−50.63 ± 1.87	−0.70 ± 0.14	101.57 ± 22.59	67.68 ± 3.25	0.82 ± 0.08	0.32 ± 0.03	0.50 ± 0.05	−11.87 ± 1.40	19.33 ± 2.84

Cell numbers (n) for the Paired (PD), Unpaired (UP), and Sit groups were 22, 14, and 15, respectively. Fluorescent cell numbers (n) for PD, UP, and Sit groups were 6, 6, and 4, respectively. Note that there were group differences in threshold, latency, and AHP amplitude. The difference in threshold and AHP amplitude was between the PD and UP group. The difference in latency was between the PD and UP and Sit groups.
