awakening

The return to the polysomnographically defined awake state from any non-REM or REM sleep stages. It is characterized by alpha and beta EEG activity, a rise in tonic EMG, voluntary rapid eye movements, and eye blinks. This definition of awakenings is valid only insofar as the polysomnogram is paralleled by a resumption of a reasonably alert state of awareness of the environment.
