    Electrophysiological correlates of higher states of consciousness during sleep in long-term practitioners of the transcendental meditation program
    (1997) Mason, Lynne; Alexander, Charles; Travis, Fred; Marsh, G.; Orme-Johnson, David; Gackenbach, Jayne; Mason, D.; Rainforth, Maxwell; Walton, Kenneth
    Standard ambulatory night sleep EEG of 11 long-term practitioners of transcendental meditation reporting higher states of consciousness during sleep (the experimental group) was compared with that of 9 short-term practitioners and 11 nonpractitioners (all Ss aged 21–50 yrs). EEG tracings during Stages 3 and 4 sleep show that experimental Ss had theta-alpha activity simultaneously with delta activity and decreased chin EMG during deep sleep compared with short-term controls. In the 1st 3 cycles, experimental Ss had significantly greater theta2 (6–8 Hz)-alpha1 (8–10 Hz) relative power during Stages 3 and 4 than did the combined control groups. There was a graded difference across groups during Stages 3 and 4 in theta2–alpha1 power. Experimental Ss also had increased REM density during REM periods relative to short-term controls.
