All values are shown as means ± SEM; n = 15 per age group. Discharge frequency (FRQ) was calculated from total spikes elicited upon suprathreshold 500-ms-long current injections. Spike half-width (HW) and AHP were calculated as the difference between the action potential threshold and the most negative level reached during the repolarizing phase. TSH, Threshold.
