[The electrophysiologycal and information aspects of stress development]

In the first part of this paper the modern concepts of stress and possibility of diagnostics of early stress manifestations are considered. Though significant advances of researches of this problem many methodological and methodical aspects are continued to be discussed. The categorical proff are stage development of adaptation processes and there classification [H. Selye]. A long-term studies of adaptation processes of students in semesters and exams have been conducted by authors with specially development and to accumulate new data. The second part of this paper is the survey of these results published in different time. The polyparametric technology including some electrophysiological methods with the system analysis using artificial intelligence algorithms and methods of pattern recognition permitted to show some regular dependences in relationships of electrophysiological parameters and there variations under stress development. It was shown for diagnostics of stress stages in necessary to assess not only absolute values of parameters but also there relationships, which are new diagnostics signs considering as information connections between physiological systems. The main characteristic of functional state of an organism is balance of parameter's relationships in totality, representing invariant for healthy persons. In condition of disharmony of parameter relationships there are aroused the strain, overstrain functional state or failure of adaptation in depends on a degree of misbalance. The represented new data don't contradict to known reasons and mechanisms of stress and accumulated data of its variety manifestations. As the work-hypothesis the information-wave model of appearance of psychosomatic reactions of stress is introduced.
