	Pyramidal Neuron	Interneuron	Significant Difference
Number of neurons tested	33	18
Resting membrane potential, mV	-73.0 ± 1.0	-61.4 ± 1.9	P < 0.001
Input resistance, M Ω	124.3 ± 6.3	332.4 ± 48.1	P < 0.001
Rheobase current, pA	95.7 ± 7.3	56.8 ± 11.8	P < 0.01
Action potential threshold, mV	-35.4 ± 0.4	-43.0 ± 0.9	P < 0.001
Action potential amplitude, mV	93.8 ± 0.8	88.2 ± 2.6	P < 0.01
Action potential half-width, ms	1.50 ± 0.03	1.00 ± 0.05	P < 0.001
