There are summarized literature data and results of many-year Laboratory studies disclosing principles of multiform spatial-temporal organization of different by rates neurophysiologic brain processes as the universal "language" of its informational-controlling functions. Current concepts of electrogenesis and physiological significance of ratios of gradual changes of biopotentials and impulse activity of neurons are considered in studies of cerebral mechanisms of regulation of normal and pathological states, organization of human psychic activity. Proposed and argumented is the concept of probability principle of hierarchical organization of different by rates neurophysiologic processes of the brain zones, structures, and areas in formation of the brain systems participating in provision of the higher psychic functions and states. It is proposed to discuss the concept of the brain as the "swimming", many-contour, neurodynamic informational-controlling suprasystem with universal, hierarchically organized neurodynamic structures--"functional organs" after A. A. Ukhtomskii (1978), of which formation provides an extensive informational brain capacity and a large specter of adaptive possibilities of the human organism.
