Data for membrane potentials and action potentials

	RMP, mV	AP, mV	AP Half-Width, ms	AHP Amplitude, mV	AHP Duration, ms	Number of Cells
P13–P17	−63 ± 0.9	70 ± 2.0	2.1 ± 0.1	10 ± 1.0	622 ± 99	24
P25–P32	−67 ± 1.3	73 ± 1.8	1.8 ± 0.1	12 ± 2.1	522 ± 62	15

Values are means ± SE. AP and AHP amplitude were measured from “resting” potential to the peak voltage change. AP half-width was measured at half the amplitude (measured from rest).
