Stress: information and wave mechanisms and diagnostics. Dmitrieva N.V.

This book presents the results of a polyprametric description of the dynamics of the functional state of a person when exposed to a number of stressor factors (examination session, physical activity, thermal impact, etc.), as well as with some types of stress and correction of states. A polyparametric description is based on the simultaneous registration of a number of physiological indicators (EEG, RVG, breathing, etc.) and the use of artificial intelligence tools developed by the author for their analysis online. Along with this, a syndromic analysis of polyparametric images is given, carried out in interactive mode in clinical terms. The intellectual model allows you to determine the ratio of electrophysiological processes, which in the form of information coefficients act as primary signs of stress. Their assessment of the invariant observed in a satisfactory condition helps to determine the main stages of stress development. In this case, the functional states of the voltage and

overstrain, accompanied by resonance phenomena, are defined as stress. The imbalance of information coefficients and the absence of resonance phenomena indicates a disruption of adaptive processes, that is, the occurrence of distress.

The work proposes a new resonant-wave model of stress. The fundamental novelty is the use of general principles of symmetry to analyze the geometric models of the functional state and invariability of the ratio of parameters as a quantitative measure of safety of the object. The proposed model does not contradict known facts about external and internal causes that cause stress and accumulated data on a huge variety of its manifestations. The developed concept allows us to substantiate the measurement of stress in its development, as well as approach the determination of the strategy of searching and choosing a stop and adequate correction of conditions by influencing the frequency regime of electrophysiological processes in the body.
