  • Comparison of passive and active properties of PV+ (n = 10) and ChAT+ (n = 11) MSDB neurons identified by genetically targeted eYFP expression. Vm, Resting membrane potential; Rinp, input resistance; τmem, membrane time constant; APthr, action potential threshold; APampl, action potential amplitude; APdV/dt, maximal action potential rise slope; APHalf-width, action potential width at half maximal amplitude. Values represent mean ± SD p-values (t test) and indicate statistical difference between PV+ and ChAT+ neurons.

  • ↵aOne outlier assessed by applying Chauvenet's criterion was excluded.
