[The biorhythmological mechanisms of the adaptive self-regulation of functions: the connectedness and cyclicity of intercomponent and intersystem interactions].

The paper summarizes studies carried out in the Dept. of Ecological Physiology of the Inst. Exptl. Med. and stemming from the D.A. Biriukov works. Biorhythmological basis of the mechanisms of adaptive self-regulation of functions is revealed. This enables to evolve new approaches to estimation of individual human adaptive features and of the ways of functional nonpharmacological correction of functions by means of the feedback biocontrol of neural, vegetative and somatic functions. The results of the studies have advanced human psychophysiology and found some practical application in medicine.
