We consider the human body as an open self-regulating liquid system (LS) functioning in a gaseous environment (GE). This paper considers two systemic critical points. The first is birth (F): the start of a set of trajectories of unsynchronised circadian rhythms during the transition from the liquid intrauterine to the external gaseous environment; the appearance of gas-exchange metabolic function of the lungs; restructuring of the vascular, nervous, endocrine systems, activation of the hypothalamus. The second is biological mortality (M), which we consider as a zone of convergence and final degradation of all circadian rhythms and homeostatic mechanisms. "M" is an attractor of homeostasis of biological life forms. The graph shows a significant phase similarity in time and vector parameters "F", "M", "IPB" (integral population biorhythm) and Schumann resonance (SR). SR action is considered as an external regulatory influence on processes (F/M), the dynamics of which has no signs of interaction at short time intervals. Parametric resonance is considered as a universal communicator of external and internal interactions.

The bifurcation point for all circadian rhythms is cardiac arrest, following which brain activity is determined by the time interval of metabolically permissible activity. In the terminal phase (from cardiac arrest to isoelectric EEG), all the trajectories of LS regulation in the GE are focused in the attraction pool of the attractor (M). High brain activity and growing dynamic chaos in the terminal phase lead to the mobilisation of the entire range of compensatory brain information constructs aimed at restoring homeostasis (the uncontested goal of this phase). The final stage of brain activity in the final stage of the terminal phase, with the total exhaustion of regulatory resources, leads to the creation of an extract from the entire spectrum of homeostasis regulation algorithms, an integral information package of maximum density.

The dominant communicative and integrative role during the terminal phase is played by brain structures, the activity of which is manifested by an EEG gamma rhythm spectrum. We believe the gamma-rhythm burst in this phase is a sign of the activity of brain structures that include a network gateway for information conversion (consciousness).
