Changes in spike form and the action potential firing in the TG neurons during application of depolarizing pulses in naive and IAN-transected rats under current clamp conditions. The stimulus currents were applied at 50 pA steps under current clamp conditions. A and B: Sample recordings of action potentials of TG neurons from naive and IAN-transected rats. Spike amplitudes of action potentials were calculated from the distance between two dotted lines in B. The action potential was induced at the threshold (1T), two-times (2T) and three-times (3T) the threshold level. C: Mean spike amplitude of TG neurons from naive rats and IAN-transected rats. D: Mean overshoot of TG neurons from naive rats and IAN-transected rats. E: Mean threshold current in naive and IAN-transected rats. F: Mean number of spikes evoked in naive and IAN-transected rats during depolarization step pulses at 1T, 2T and 3T. * p < 0.05 (vs. naive)
