Figure 4.

Time course of the development of heat-evoked behaviours after injury of the mental nerve. Withdrawal latencies to radiant heat stimulation of the chin were significantly increased 6 days after chronic constriction injury (CCI) of a mental nerve (A), but not after partial tight ligation of the nerve (PTL; B) or sham operation (C). The operation was performed on day 0 (indicated by the dashed line). Symbols are mean ± 1 S.E.M. Asterisk indicates significant differences between ipsilateral and contralateral sides (P < 0.03; 2-factor repeated measures ANOVA followed by Tukey’s test post-hoc).
