The effect of 0.2 mm sevoflurane on tonic action potential firing properties

	Resting potential (mV)	AP threshold (mV)	Peak amplitude (mV)	Half-width (ms)	ΔV/Δt	Input resistance (MΩ)	n
Control	−59.4 ± 0.6	−35.8 ± 0.6	23.6 ± 3.1	0.55 ± 0.01	0.51 ± 0.1	211 ± 11	9
0.2 mm sevoflurane	−57.5 ± 1.7	−35.3 ± 0.9	22.8 ± 2.9	0.58 ± 0.02	0.43 ± 0.1*	229 ± 10*	9

The series of action potentials was induced by injection of 40 pA current in neurons with membrane potential of −60 mV prior to the application of depolarizing current pulses. The data are presented as mean ± SEM.
