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).
