REM Sleep

REM Sleep

-------------
REM sleep is characterized by three things: (a) Muscle atonia (b) Rapid eye movement and (c) Desynchronized mixed frequency waves are seen
------------
Saw tooth appearance of waves are seen in REM sleep- REM sleep is commonly not seen in regular EEG readings (takes about 20 minutes, normal REM latency is 90 minutes or so)
------------
Appearance of REM sleep in regular recordings or much earlier than expected is called as SOREM period (Sleep Onset REM period). Very suggestive of Narcolepsy, but can also be seen in significantly sleep deprived individuals
