Action potential (AP) morphology of noradrenergic neurons in the locus coeruleus (LC) of wild-type (WT) and Ndn +m/−p mice. a Representative spontaneous AP morphology of LC-NE neurons. b–e The resting membrane potentials (b) after-hyperpolarization amplitude (AHP) (c), AP amplitude (d), and AP half width (e) showed no differences for LC-NE neurons of WT (n = 16 cells from 12 animals) and Ndn +m/−p (n = 16 cells from 11 animals) mice, although there was a trend that the AHP of Ndn +m/−p mice was smaller than that of WT mice. Statistical analyses were performed using Student’s t test. Data are presented as mean ± SEM
