The actioculographic monitor (AOGM) is a newly developed, flexible system for sleep recording using three criteria: eye movements, body movements, and submental electromyogram. The signals are recorded on a four-channel Medilog casette tape and displayed by a mingograph at very low speed. The record is then scored after certain criteria for stages wake, nonrapid eye movement, and rapid eye movement sleep. High statistical correlations were obtained when scoring of the AOGM was compared to scoring of standard polygraphic sleep recordings.
