From: Cutaneous nociceptors lack sensitisation, but reveal μ-opioid receptor-mediated reduction in excitability to mechanical stimulation in neuropathy

Figure 4

Discharges of sensory fibres to mechanical stimulation following nerve injury. Discharge rates to nanomotor stimulation were not significantly altered in RAM (Aβ), D-hair (Aδ) and C fibres (P > 0.05; 2-way RM ANOVA) (A, C, E), but were diminished in SAM (Aβ) and AM (Aδ) fibres in injured nerves (*P < 0.05, compared to uninjured nerves; 2-way RM ANOVA, Bonferroni t test) (B, D). In uninjured nerves, the number of fibres from sham-operated and nonoperated nerves is the same as in Figure 3. All data are expressed as means ± SEM. N, number of fibres.
