摘要: Background and objective As compared to preceding wakefulness, stage 1 sleep is characterized by elevated slow-wave activity (SWA) that regarded as the most popular electroencephalographic (EEG) indicator of debt. However, some other indicators did not suggest such elevation until 2 sleep. In this paper, a more direct signature left debt in EEG spectrum named “spectral component score” (SDS) was introduced, its changes throughout three stages non-rapid eye movement (NREM) were studied.
