Action potential firing patterns and frequency of TTXs/TRPM8 and TTXr/TRPM8 DRG neurons. A-B) Fraction of cells that had tonic or other types of action potential firing in TTXs/TRPM8 (A) or TTXr TRPM8 cells (B). C) Relationship between action potential firing frequency and depolarizing current steps for the cells that fired tonic action potentials. Red, TTXs/TRPM8 cells. Blue, TTXr/TRPM8 cells. Data represent mean ± SEM, *P < 0.05.
