Awakening from rapid eye movement (REM) sleep leads to faster recovery of consciousness compared to slow-wave sleep (SWS). In a study with healthy volunteers, it was observed that motor responses to auditory stimuli resumed within 20 seconds after alpha brain activity began during REM, versus 25 seconds for SWS. Notably, pre-attentive processing of stimuli occurred earlier during REM. This indicates that the presence of alpha activity alone does not guarantee awareness or motor response, shedding light on sleep disorders and consciousness dissociation.
