The article deals with the problem of the brain\\\'s psychic activity during wakefulness and sleep. It is noted that all the current understanding of sleep and wakefulness are based just on the study of neurophysiological processes, without taking into account the mental (psychic) activity of the cerebral mechanisms that are still poorly understood. It is shown that the psychic state of a person, and sleep are closely related. New approaches to study of the nature of the mental activity of the brain, based on the methodological principle: «mental processes can be directly registered and investigated based on the participation of living structures» are introdused . The basic plane of the system organization in the brain\\\\\\\\\\\\\\\'s psychic activity during sleep and while awake is proposed.
