Figure 5From: Operant behavioral responses to orofacial cold stimuli in rats with chronic constrictive trigeminal nerve injury: effects of menthol and capsazepineCumulative contact time of orofacial operant tests in ION-CCI rats following administration of capsazepine. A) Cumulative contact time of orofacial operant tests in ION-CCI rats at 24 °C (n=7). Open circles, vehicle injection; closed circles, capsazepine injection. B) Cumulative contact time of orofacial operant tests in ION-CCI rats at 17 °C (n=7). Open squares, vehicle injection; closed squares capsazepine injection. C) Cumulative contact time of orofacial operant tests in ION-CCI rats at 12 °C (n=7). Open triangles, vehicle injection; closed triangles, capsazepine injection. Data represent Mean ± SEM; ** p < 0.01; *** p<0,001.Back to article page
