Theory of Chaos and Self-Organization in Description of Functional Human Body Systems

Abstract

Attempts to describe the behavioral dynamic model of the functional systems of the human body has traditionally been based on models of periodic and quasi-periodic processes (breathing, cardiac work, brain biopotentials, etc.). The paper assumes a new approach to the description of the voluntary or involuntary periodic or quasi-periodic motions and other dynamic processes (normal and pathological) in human body. It is shown that the norm is often chaotic behavioral dynamics of the state vector of the human body and the periodic or stationary modes of dynamics are typical of pathology, while in medicine for a long time the views were diametrically opposite. The paper presents the application of calculation method of quasi-attractors in estimation of biomechanical processes (sighting or Parkinson’s disease). The informational significance of the method is shown.

Functional systems of students’ organism depending on physical fitness to physical load

“…It ensures self-regulation of physiological functions and sustains life activity at optimal and relatively constant level. In this respect human organism is half closed thermodynamic system, which consists of different organs and tissues [30]. According to requirements of internal medium and organism action's stability in respect to external conditions two systems are used: vegetative nervous system (VNS) and endocrine system.…”

“…Ер is directly information form of alive, which plays the role of feedbackє between two regulation systems. Ер is a formation component of organism's functional system (OFS) in [30,34].…”
