Comparison of electrical properties of ChR2 expressing neurons

Genotype	Resting potential, mV	Input resistance, MΩ	Threshold, mV	Action potential duration, ms	Action potential amplitude, mV	Action potential overshoot, mV
ChR2−	−58.3 ± 1.8	126 ± 13	−29.6 ± 2.2	1.02 ± 0.11	93.4 ± 5.9	35.7 ± 1.2
ChR2+	−61.4 ± 1.4	110 ± 4.5	−35.4 ± 2.2	1.11 ± 0.09	99.5 ± 7.1	38.1 ± 0.2

Sample size is 10 cells for each group. There was no statistically significant difference (P > 0.05) in the mean value of any parameter between the two types of neurons.
