Effect of mental nerve injury on capsaicin avoidance. A: capsaicin consumption per group plotted vs. concentration 1 mo post-surgery. There were no significant between-group differences (ANOVA, F2,417=0.5, p>0.05), and no significant pre- vs. post surgery within-group differences. B: As in A, 6 mo post-surgery. There was a significant group effect (F3,697=4.18, p<0.05) with capsaicin consumption by the CCI significantly less compared to pre-surgery (*, p<0.05, LSD). C, D: % licks from the capsaicin-treated bottle vs. capsaicin concentration at 1 and 6 months post-surgery, respectively. The CCI group licked significantly less capsaicin (*, p<0.05) at 6 months compared to pre-surgery (Selzer and sham groups omitted).
