Ultraslow information control systems in the integration of life activity processes in the brain and body

The published data and the results of studies of the Department of Human Neurophysiology, revealing the place and importance of ultraslow information-control systems in the study of mechanisms for the integration of interorgan and intersystemic interactions, with the leading role of CNS and the autonomic nervous system, are summarized. The existing notions of the universality and commensurability of amplitude-time parameters, ultraslow bioelectric potentials (USBPs) recorded in the brain and the brain-controlled systems and organs have been considered. Experimental justifications for including one of the USBP types, a stable potential in the millivolt range in the vertex-tenar derivation (the omegametry method) in the psychophysiological approach are provided. This approach consists of choosing complementary integral psychological and physiological parameters permitting the study of the contingency of the mechanisms that control the functional state (wakefulness level) with specific features of the organization of higher mental functions and adaptive behavior, as well as in differentiating diagnostic markers: (a) the balance level and disintegration of intersystemic interaction in the body; and (b) disturbances of compensatory-adaptive possibilities and the adaptation reserve of the body. The prospects of using this approach in theoretical and applied studies on developmental psychophysiology, child psychoneurology, and functional neurology of chronic diseases of the nervous system have been considered.
