REM forårsakes av et vedvarende fall i serotonerg aktivitet. Studier på mennesker og dyr i våken tilstand viser at blokkering av serotoninfunksjon kan utløse aktivitet i hjernestammens orienteringssystem. Serotoninblokade gir opphav til støtvis gammafyring i den kolinerge hjernestammen og i våken tilstand er denne fyringen forbundet med hallusinasjoner hos mennesker. I tråd med dette forekommer hallusinasjonene i REM samtidig med at serotonin-nivået er betydelig lavere enn i andre søvnfaser.

Sleep and our circadian rhythm similarly are an innate part of human biology and psychology, shared by people from every culture that has ever existed. According to new research, the neurons that regulate biological clock actions relating to the circadian rhythm and sleep may also play a role in regulating pleasure.

SLEEP - things not to do in bed: No Electronics - blue wavelengths mess with our natural melatonin production, making it harder to fall asleep. ____ Don't Toss and Turn - if you can't sleep, get out of bed and do something calming until you feel tired. Tip: read. ____ Don't Work - this teaches your brain your bed is for things other than sleeping. ____ Don't Snooze - set your alarm a little later and work on getting up rightaway, otherwise you're just interrupting your REM periods of sleep.

This pins goes more deeply into EEG brain wave patterns. Each stage is depicted with its correlated EEG. Each wave is different going from alpha waves to delta waves. And all changing drastically between stages.
