Sleep parameters in B6J, B6N, and B10J. Total time spent in (A) wake, (B) NREMS, and (C) REMS in 24-h day, 12-h light phase, and 12-h dark phase. Episode duration of (D) wake, (E) NREMS, and (F) REMS. EEG power spectra during (G) NREMS and (H) REMS. (I) The delta density (1–4 Hz) during NREMS and (J) the theta density (6–9 Hz) during REMS. Male B6J (n = 20), B6N (n = 20), and B10J (n = 20). All data are shown as the mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. (A–H) Two-way ANOVA followed by Tukey’s test.
