A device named “dream detector” was constructed to automatize the technique of studying dreams during the REM period of sleep (REMP). The principle of the dream detector is to identify the REMP automatically by counting the number of electrooculographically recorded REMs during the period of relative silence in EMG records. When the count number of EMs reaches a preset value, an alarm buzzer is turned on automatically to awaken the S . In preliminary experiments on 5 S s, 62 out of 70 REMPs (88.6%) in a total of 16 experimental nights were correctly detected by using this device. In only 5 instances (3.5%) was the buzzer turned on during periods other than REMPs. The rate of correct detection was 56% for the first REMP of the night, 93% for the second REMP, and 100% for the following REMPs.
