TIPSters, I know what Intro Psych texts say about stages of sleep and what kinds of brain waves there are in each, et. But when the EEG from a sleeping person is examined, is it obvious when the person passed from one stage into another? Or is it gradual? Could a line be drawn across the paper marking where Stage 2 stops and Stage 3 starts?
I don't know about the 2nd question, but I can answer the first one. There is not an absolute number, but according to what I have read, stage 3 is marked by having at least 20% Delta waves and state 4 is marked by having at least 50% delta waves.
