0075 Rem Sleep Is Bimodal

[摘要] IntroductionThe classic model of sleep and sleep scoring differentiates REM sleep, wake and stages of NREM which increase in depth grade. Alternate methods of sleep characterization include cyclic alternating pattern, sleep power kinetics (delta, alpha, etc), slow-oscillation density metrics, the Odds Ratio Product, network based approaches such as time delay stability, and ECG-spectrogram (cardiopulmonary coupling), the latter showing an intrinsic bimodality of NREM sleep. REM sleep has so far been considered a unitary state.
