Average power spectra density in 11 regions across NREM, REM, and Wake stages. For each plot, the NREM stage is represented in blue, the REM stage is represented in red, and the Wake stage is represented in green. A total of 11 regions located on the left and right in the whole brain are described, including the midline region, the frontal region, the parietal region, the central region, the temporal region, and the occipital region. The line represents the mean value, the shade represents the standard error range.
