Fig. 4From: The influence of rapid eye movement sleep deprivation on nociceptive transmission and the duration of facial allodynia in rats: a behavioral and Fos immunohistochemical studyThe time course of the VFMF threshold level in each supradural capsaicin infusion group. The duration of reduced VFMF threshold in the REMSD-Capsaicin group was significantly longer than in the NonSD-Capsaicin group (* indicates p < 0.05 between groups; blank circles and squares with a dotted-line indicate p < 0.05 compared to baseline, error bar indicates 95% confidence interval).
