Values are means ± SE, except for Cm, which is expressed as median (25th to 75th percentile). Em, resting membrane potential; Rin, input resistance resistance; Cm, membrane capacitance; AP, action potential; AHP, after hyperpolarization; τAHP, time constant for the decay of the AHP; Rate Rise, the maximal rate of rise of the AP; Rate Fall, the maximal rate of fall of the AP.
