Figure 5

The effects of GREE on EEG power density of wakefulness (a), REM sleep (b), and NREM sleep (c). The power density was departmentalized into -wave, -wave, and -wave. Each wave represents the mean with S.E.M. (). The significance of the effects of the compounds was assessed using analysis of variance (ANOVA). Where there was significant variability, the individual values were compared using Holm-Sidak test. , compared with that of the naive control.
