↵2-a Cells were held at −65 mV; sAHP was obtained by passing 0.1 nA through the recording microelectrode.
↵2-b Number of action potentials which were evoked by a depolarizing pulse 0.5 nA, 600 ms; cells were held at −70 mV.
↵2-150 Significantly different from those of the vehicle control group (p < .05, t tests with Bonferroni’s correction).
