C fibers	-63.0 ± 1.5	0.6 ± 0.1	3.1 ± 0.5	1.38 ± 0.01
(n = 15)	(51.0–74.0)	(0.4–0.7)	(2.5–4.6)	(0.81–2.85)
Aδ fibers	-67.7 ± 2.4	5.9 ± 0.8	1.8 ± 0.6	0.63 ± 0.05
(n = 18)	(55.0–71.0)	(1.4–12.5)	(1.6–2.1)	(0.30–0.99)
Aβ fibers	-65.1 ± 1.8	19.6 ± 1.3	0.8 ± 0.2	0.29 ± 0.01
(n = 20)	(52.0–76.0)	(14.1–23.4)	(0.04–1.34)	(0.19–0.43)

RMP, resting membrane potential; CV, conduction velocity; TSI, threshold of stimulus intensity. APD, duration of action potential measured at its half-maximal amplitude; Values are shown as means ± SEM.
