Figure 3

Increase in numbers of action potentials after NaHS application. A, action potentials were induced in TG neurons by a 2X (120 pA) and 3X (180 pA) rheobase current injection in the absence (top) or presence (bottom) of 250 μM NaHS. B, Bar graph showed significant increase in numbers of APs after NaHS application. C, APs (upper traces) were induced by a ramp current injection (lower traces, 200 pA, left; 500 pA, right) in the absence (top) and presence (bottom) of 250 μM NaHS. D, Bar graph showed a significant increase in numbers of APs in response to ramp stimulation after NaHS application. * p<0.05 (n=6) versus control (PRE).
