[EEG pattern as an instrument for evaluation of neurophysiological mechanisms underlying adaptation disorders].

[Article in Russian]


The method of statistical evaluation of probable interaction between the main constituents of bioelectrical activity of the brain (BEA) enables to reveal the character of intercentral relations both under normal conditions and at adaptation disorders of different severance. Several types of statistic interactions have been revealed between EEG components (SSIC) correlating with normal interrelations between cortex and subcortex, level of preferential involvement of non-specific brain formations (cortex, thalamic, hypothalamic and brain-stem) into the process, and the degree of instability of neuro-dynamic processes. The findings obtained have shown the degree of expression of adaptation disorders to be connected with gradual destruction of "functional nuclear" within alpha-range, amplification of statistical interrelations with beta-EEG and teta-EEG components and formation of pathological nuclear structures within the ranges aforesaid.
