Abstract
Abstract An apparatus for monitoring the behaviour during sleep of a living organism for measuring the mental condition of the living organism while the latter is sleeping, which essentially comprises an analog-to-digital signal conversion device for electroencephalograms, movements of the eyes and electromyograms, a data processor for processing the output signals from the conversion device and a tape recorder for recording the signals indicative of the electroencephalograms, the eye movements and the electromyograms. Also provided is a method of monitoring the behaviour during which can be performed by the apparatus herein proposed.
