[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.

[Super-slow oscillations of cerebral biopotentials in patients with transient circulatory disorders in vertebral-basilar basin].

The paper deals with a study of 30 patients with transient disorders of circulation in the vertebro-basillar basin. Besides the routine methods of clinico-laboratorial examinations, for the first time in neurological practice a new method of electrophysiological registration was used: superslow fluctuations of the brain biopotentials. The patients were examined during the interattack period.
