The theory of functional systems: general postulates and principles of dynamic organization (dedicated to the Anokhin Centenary).

Dedicated to the Centenary of the outstanding Russian physiologist P.K. Anokhin, this article postulates the main principles of the general theory of functional systems. The system-formation role of useful adaptive results forming the functional systems of different levels is underlined. The peculiarities of mechanisms of self-regulation of functional systems, their isomorphism, holographic characteristics and selective inclusion into the functional systems of different organs and tissues are revealed. It is shown that interaction between numerous functional systems that form the whole organism is built on the principles of hierarchy, multiparametric interaction, sequential interaction, systemogenesis, and system quantization of life processes. The interrelation of reflex and functional systems is also considered.
