Resting membrane potential, mV	−64.4±1.0	−55.3±1.7	P<0.01
Membrane capacitance, pF	87.3±3.7	36.9±1.9	P<0.01
Input resistance, MΩ	77.5±4.6	355.1±44.2	P<0.01
Rheobase current, pA	94.3±6.8	27.5±4.0	P<0.01
Action potential threshold, mV	−37.3±1.1	−39.2±1.0	P = 0.34
Action potential amplitude, mV	98.8±1.8	89.0±1.7	P<0.01
Action potential half-width, ms	1.55±0.04	1.03±0.06	P<0.01

Values are Mean±SEM. Significant differences were obtained by the two-tailed, unpaired student t-test.
