Comparison of the number of c-Fos-positive-neurons and ratio of c-Fos-orexin-double-positive-neurons/orexin-neurons in LH of 1-day/8 days/15 days RF-mice. The mean (± SEM) of c-Fos positive neurons (A) and the ratio of c-Fos-orexin double-positive neurons to orexin neurons (B) for ten subjects are shown on the y-axis. Data are reproduction of RF groups shown in A–B of both Fig. 4 and Fig. 7. **P < 0.01; ***P < 0.001 difference among the LH of the 1, 8, and 15 days RF mice according to one-way ANOVA with Bonferroni’s multiple comparison test
