From: Sex-dependent effects of chronic jet lag on circadian rhythm and metabolism in mice
Sex-dependent changes in body temperature and activity rhythms under CJL. (A) Actograms of locomotor activity and body temperature rhythms under control or chronic jet lag (CJL) conditions in female and male C57BL/6N mice. (B) Chi-square periodogram based on body temperature rhythms under light-dark cycles (LD, control or CJL conditions) or following constant darkness (DD). The blue line is the significance level (p = 0.001). (C–F) The circadian period (C, E) and rhythm robustness (Qp) (D, F) of activity and body temperature rhythms of female and male mice under LD (C, D) and following DD (E, F), based on chi-square periodogram. Data are presented as means ± standard errors of the means (S.E.M). Two-way ANOVA followed by Šidák’s multiple comparison test, * p < 0.05, ** p < 0.01, **** p < 0.0001
