Individual and typological  human features in adaptation   

   

 

 

 

 

 

 

 

It is established that the organism tolerance to ecologically significant factors is conditioned by an adaptive plasticity of the nervous system and its biorhythmological characteristics. To clarify the character of interrelation among EEG components (zero-crossing) one of the methods from the theory of finite Markovian chains was used, aimed at the study of the structural properties of systems in the consecutive interaction of their elements (fig. 1, 2 ,3).

 Probability-oriented graphs for interaction of alpha-waves in ranges 8, 9, 10.5 and 12 Hz before cardiotraining. 
Numbers at tops of the graphs are the probabilities of the appearance of alpha-waves in the above mentioned ranges. The width of oriented graph lines is proportional to the intensity of alpha-waves interaction.

Probability-oriented graphs of space interaction in intact EEG, alpha- and beta-ranges before cardiotraining (left), and after the end of cardiotraining (right). 

The sizes of hatched sectors are proportional to the unconditional probabilities of beta-, alpha-, theta- and delta-rhythms (clockwise from vertical line). Numbers at tops of the graphs are the probabilities of the appearance of alpha- and beta-waves in the appropriate regions of brain cortex. IB is a hemisphere balance.

Three types of adaptability of the basic nervous processes - high, middle and low plasticity were allocated on large contingents of subjects. This classification has proved to be valid in studying of reactions to electromagnetic, chemical, climatic and geographical factors, under intensive operational and professional activity. 

The adaptive plasticity is determined by a set of adaptagenious biorhythms of an organism. The high level of development of rhythmic physiological activity corresponds to high probability of the normal course of the adaptation process. The low plasticity predetermines the functioning of systems on the limit of physiological resources. The result of it is some suppression of cyclic interactions of the brain structures and other different functional disorders. These non-specific phenomena underlie subclinical pathology. The intensity of interaction of bioelectrical activity in the right hemisphere of the brain is reduced when the patient's time contact with ecological factors is being increased and is accompanied by decrease of functional reserves of the brain. 

Now the procedure of determination of individual and typological features (belonging to any group) and the current functional brain reserve is obligatory for every subject (patient). The fragments of the method of determination of the brain functional reserves are patented.
