Effect of capsaicin on membrane properties of CeC neurons

		Resting membrane	Input resistance	Whole-cell
Treatment	Recorded side	potential (mV)	(MΩ)	capacitance (pF)
Capsaicin	Left (n = 84)	−58.5 ± 0.9	195.2 ± 9.2	14.5 ± 0.9
	Right (n = 116)	−59.9 ± 0.7	214.2 ± 9.1	15.3 ± 0.7
Vehicle	Left (n = 37)	−60.4 ± 1.1	228.7 ± 23.5	16.6 ± 1.4
	Right (n = 42)	−60.7 ± 1.3	245.2 ± 19.6	15.6 ± 1.3

Membrane properties and whole-cell capacitance of CeC neurons from either side in capsaicin- or vehicle-treated rats recorded 7–9 days after spinal nerve ligation. Values are expressed as the mean ± SEM and were measured immediately after establishment of the whole-cell mode. Junction potentials were not compensated. No significant differences in the resting membrane potential, input resistance or whole-cell capacitance between the treatment groups or between the left and right CeCs were observed (ANOVA followed by Bonferroni post-hoc test). Numbers in parentheses indicate the number of neurons.
