[Human hypnosis and super-slow electrical activity of the brain].

The authors studied the transformation of infraslow oscillations of brain potentials in 15 patients with neuroses during 50 sessions of hypnosis. The results of such studies permitted to distinguish some important traits in the changes of infraslow oscillations of brain potentials in different stages of hypnosis. It is concluded that a study of these changes during hypnosis may establish some correlations between the physiological state of the brain and the unconscious mental processes.
