Compare REM and NREM sleep with respect to EEG activity, muscular activity, and cognitive activity
What will be an ideal response?
NREM sleep refers to Stages 1 through 4, collectively, and thus is characterized by varied EEG activity. As sleep progresses through these stages, sleep becomes progressively deeper; brain waves correspondingly decrease in frequency and increase in amplitude. Muscle tension also decreases as sleep deepens. Dreams occasionally occur during NREM sleep, but these tend to be infrequent and far less vivid than REM dreams.
REM sleep is also a deep sleep in the sense that it is relatively difficult to awaken a person from this stage. Muscle tone is so relaxed as to leave the body virtually paralyzed. The eyes, however, move beneath closed lids. The EEG shows beta activity, as if the person were wide awake. This paradoxical finding can be accounted for by the fact that REM is the stage during which most dreaming occurs.
