非快速動眼睡眠
非快速動眼睡眠(英語:non-rapid eye movements)是指沒有快速動眼運動的睡眠。在這段睡眠期間,大腦的活動下降到最低,使得人體能夠得到完全的舒緩。不同於快速動眼睡眠,在這段期間眼球幾乎沒有運動。作夢在此時也很少出現,而肌肉在非快速動眼睡眠時並不會麻痺。 另外,人體在非快速動眼睡眠將處於副交感支配的狀態。
非快速動眼睡眠的分期
非快速動眼睡眠可分為四個時期:
多型態睡眠評估
以下是各期在腦電圖上顯示的資料。
圖表所呈現的是於30秒之間的變化。資料依序代表了雙眼、下巴、腦波、腳、麥克風、外側神經肌電圖、胸鎖乳突肌的活動(sterno cloidal mastoid activity),口鼻呼吸、胸廓活動(thoracic effort)、腹部活動(abdominal effort)、心電圖、血氧以及身體姿勢。
腦電圖(EEG)以紅框凸顯。第二期的睡眠紡錘波加以紅色底線。
