Decreased threshold and increased amplification gain in duck TG neurons. (A–C) Exemplar traces (A) and quantification (B and C) of MA current in TG neurons in response to mechanical stimulation with a glass probe. Current was obtained in the voltage-clamp mode in the whole-cell configuration. Activation threshold and gain (slope) were determined by linear approximation of the rising current component. Box: 50 percentile with a median (horizontal line) and mean (plus sign). Whiskers: 1–99 percentile. n = 41 (mouse) and 66 (duck); 11–36 cells in each group. n.s., not significant (P > 0.05). *P < 0.05, **P < 0.01, nonparametric Mann–Whitney U test.
