Abstract
A method and apparatus are provided in which an REM sleep state is accurately identified by detecting and counting a selectable number of eye movements within a selectable time interval. A body movement sensor is used to prevent false indications of REM sleep by inhibiting such indication upon sensing of body movement. An eye movement sensor which uses IR light transmission across an eye is disclosed.
