Stage 1 sleep is a transition period from wakefulness to the other 3 stages of non-REM sleep. It is of short duration, usually lasting only from 1 to 7 minutes. Stage 1 sleep is characterized by low voltage, mixed frequency EEG, as well as some slow, rolling eye movements and some rel...
NREM sleep is otherwise known as the combination of sleep stages 1, 2, 3, and 4 as identified by the Rechtschaffen and Kales "classic criteria" (Rechtschaffen & Kales, 1968 ). General descriptions of AASM scoring criteria for each NREM sleep stage are briefly stated. N1 is characterized by...
Sometimes, you may spend more sleep time than usual in the REM stage. Your REM sleep can be more frequent, deeper, and more intense. This is called REM rebound, and it can happen if you’ve been sleep deprived, meaning you’ve been getting less than 7 hours of sleep per night. Also...

The type of sleep traditionally called 'Non-REM sleep' has major thalamocortical sleep (TCS) pathway activities that explain TCS waveforms on the polysomnogram (PSG). As currently scored, normative TCS comprises 80% of human sleep, and appears to be complex in its structure and functions, acr...
The midbrain region ventrolateral periaqueductal gray (vlPAG) is known to be important for gating REM sleep, but the underlying neuronal mechanism is not well understood. Here, we show that activating vlPAG GABAergic neurons in mice suppresses the initiation and maintenance of REM sleep while ...
