Table 1 Effect of capsaicin on membrane properties of CeC neurons

From: Role of capsaicin-sensitive C-fiber afferents in neuropathic pain-induced synaptic potentiation in the nociceptive amygdala

   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
  1. 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.
