Figure 4. Quantification of common sleep parameters is highly similar when using manual or algorithmic scoring.

(A) No significant differences in state-dependent power spectra were observed when computed using manual/algorithmic scoring methods. Each line depicts mean +/− standard error. (B) Slow wave activity (SWA) exhibits a similar homeostatic decline across the light period with both scoring methods. (C–D) Total durations and mean bout durations are similar across both scoring methods, with the exception of a significant increase in light-period REM duration and decrease in light-period waking duration. *p < 0.05 W—Waking; NR—NREM sleep; R—REM sleep.
