28] found significant alpha (7-12 Hz) EEG non-REM sleep
anomaly which is commonly termed in slow wave and REM sleep and non-REM sleep
physiology as alpha intrusion or EEG alpha sleep disorder.
In addition, they experienced greater length of valuable non-REM sleep
Dan is continuing her studies of the neurons that affect not only REM sleep, but also non-REM sleep
Polysomnography indicated no significant sleep-disordered breathing or limb movements but did reveal episodes during non-REM sleep
consistent with confusional arousal.
In separate experiments, the researchers found that motor cortex neurons that were active when mice ran on a treadmill were also active later during non-REM sleep
, which spans several stages of sleep and accounts for about three-quarters of sleep time in people.
Often I can guess the formation must be in a dream, or in the mental activity of non-REM sleep
, because I will wake up in the middle of the night, and find some realization has appeared, uninvited.
In a second experiment, they divided the sleep cycles into rapid eye movement (REM) and non-REM sleep
, and then induced the conditioning during only one phase or the other.
Dreams can occur in REM sleep, and non-REM sleep
, which can be a deep or light sleep.
In a nap, we go into non-REM sleep
stages I or II," says Dr.
The team used Polysomnography to assess brain-wave activity, REM and non-REM sleep
, and sleep apnea by measuring breathing disturbances and levels of oxygenation during sleep.
Problems with all stages of sleep can contribute to such disorders, but rapid eye movement (REM) sleep and the deep stages of non-REM sleep
are the most vulnerable.
5'UMP is known to encourage both REM and non-REM sleep
