Figure 2From: Temporal dynamics of EEG activity during short- and long-wavelength light exposures in the early morningThe EEG power spectra for exposure to short- (circles) and long-(squares) wavelength lights, and darkness (triangles). Data averaged for all subjects, and EEG measurement periods collected during the last 48 minutes (i.e., EEG intervals 2–7) were included.Back to article page
