There are state-related differences in respiratory control between the sleep and wake states and between the five stages of sleep, most predominantly between stages 1 through 4 non-rapid eye movement
(NREM) and rapid eye movement (REM) sleep.
The mice manifested the same abnormalities of sleep patterns, including rapid eye movement (REM) sleep at the beginning of a sleep period instead of after a normal period of non-rapid eye movement
Slow wave sleep (SWS), one of the deeper stages of sleep, is characterized by non-rapid eye movement
(non-REM) from which it's difficult to awaken.
The stages of normal sleep are measure by the voltage of electrical impulses and split into two distinct states: non-rapid eye movement
(NREM) sleep and REM sleep.
More specifically, rocking increased the duration of stage N2 sleep, a form of non-rapid eye movement
sleep that normally occupies about half of a good night's sleep.
Once the subject was in non-rapid eye movement
(NREM) sleep, the researchers reduced the CPAP level to the least amount needed to prevent airway obstruction.
In general sexsomnia features are the following: Originating in most cases from non-rapid eye movement
sleep, occurs any time during sleep, wide spread autonomic activation, sexual arousal frequently present, duration possibly exceeding 30 minutes, exceptional violence or injurious behavior, exceptionally walking out of bed, predominantly in adults.
