title: [Continuity and prospects of development of researches in area system-integrativity of psychophysiology of functional state and cognitive activity].
abstract: In the review one of actual problems of psychophysiology in studying a phenomenon of integration of mechanisms of regulation of state of a brain and features of the organization is discussed by a brain of cognitive activity. Basic value of results of long-term researches of academician N.P. Bechterevoj and of her school is opened in the field of neurophysiology of functional states as bases of the organization of mental activity in conditions of direct, long and sparing contact to a cortical and subcortical structures of a brain, with the help long-term intracerebral electrodes. Arguments about a commensurability and complementary value similar on amplitud-time parameters slow and superslow gradual changes of neurophysiological processes registered simultaneously in identified zones of subcortical structures of a brain and with removal from a surface of a head in cortical projections of basic integrativity of the centres are submitted. Representations about a brain as difficultly organized "swimming" many-contour, neurodinamic informational-controlling suprasystem with hierarchically, probability a principle of the organization different on speeds and intensity of processes of the ability to live participating in maintenance of a condition of rest, mental conditions and cognitive activity are formulated and argued. At the limited set universal neurodinamic "languages", the brain has the multiregister mechanism of regulation of conditions and selectivity of mechanisms of the integration providing the contribution differing on information maintenance gradual neurophysiological of processes of different levels of the structurally functional organization in formation of brain systems of maintenance of concrete kinds of cognitive activity.
