Effects of DAMGO on discharges of AM (Aδ) fibres with elevated mechanical thresholds in injured nerves. Baseline discharge rates of AM nociceptors to the nanomotor stimulation were not significantly changed by DAMGO (100 μM) or control buffer (P > 0.05; 2-way RM ANOVA). Data are expressed as means ± SEM. N, number of fibres.
