ABSTRACT
These data obtained shows the typological pattern of the brain neurodynamics to be related to functional self-controlling mechanisms as reflected in probable structure of the interlinks among the EEG basic rhythms. Three types were singled out with respective dynamics of the functional state readjustment under a prolonged effect of ambient factors.

The data on voluntary regulation of the heart rate in humans is given in respect to individual-typological differences of adaptive abilities, ecological specifics of ambient environment and labour, health condition (neuroses, vegetative-vascular dystonias etc.). A major role of training of the rhythmic regulatory processes for the biological feedback control, is corroborated.

On the bases of experiments with bio-control feed-back connection (automatically triggering electro-cutaneous, stimulation), a model evolved permitting to achieve stable directed changes in the levels of the systemic arterial pressure (AP) in curarized rabbits and cats. Two variants of reactions are possible: 1) gradual formation of a new raised or lowered level of AP with its pronounced retention after the end of learning, and 2) reaction of following type with directed rise in AP, which is observed only during learning. It is found that the stable shifts of the AP level are accompanied by changes in the periodicity of the third order AP waves, the heart rate showing no significant changes. It is assumed that the changes in the characteristics of the third order waves reflect the rearrangement of the mechanisms providing for homeostasis.
