Thread: Analyzing IR readings to recognize REM sleep

No idea - didn't read, but what I do know, is that IAMCoder is a good person to take contact up with for you. I believe, he's been developing REM detection algorithms from minimal EEG, which work very well for him.
What else I remember:
It was hard work and there's maybe nothing/not much else in that department freely available, or available at all.
So maybe he could help you, try pm him, I don't think, he'd mind.

Sorry for not searching deeper, but check this thread of his out: http://www.dreamviews.com/research/1...-40-hertz.html

Good luck! (good memory test for me as well...)
