Total time spent in vigilance and sleep states during the light or dark phase. (a–c) The total amount of wake, non-rapid eye movement (NREM), and REM states in the 8-h recording period of the light phase (ZT 0–ZT 8). (d–f) The total amount of wake, NREM, and REM states in the 12 h recording period of the dark phase (ZT 12–ZT 24). Data are expressed as the mean ± SEM (n = 8–9) and were analyzed by two-way ANOVA with Bonferroni correction (*p < 0.05).
