>> REM sleep EEG doesn't correspond to muscle
Correct. They don't. EEG and muscle tone are two totally different
things. Use and EMG to detect muscle tone.
It is the frequency of the *brain waves* (NOT muscle tone) I was
I am still confused over why a relatively relaxed state of the brain
(REM sleep) would have a higher frequency than a more intense state
(beta wave). So how does this work?
