ВЗАИМООТНОШЕНИЯ МИКРОЭЛЕМЕНТОВ И ЭНЗИМОВ АНТИОКСИДАНТНОГО ДЕЙСТВИЯ

calculated in the theta (4–7 Hz), alpha (7–13 Hz), beta1(13–20 Hz) and 
beta2 (20–32 Hz) EEG frequency ranges.

The data were processed using «Statistica v. 6» software. 

Intergroup differences were analyzed using the Mann–Whitney test.

RESULTS

Comparison of the spectral parameters of the baseline EEG in the 

two groups showed that subjects with a high results of the cognitive
tests were characterized by
a significantly higher power of the EEG 

alpha rhythm in the right (p=0.021) and left (p=0.014) parietal, right 
(p=0.025) and left (p = 0.018) central, right (p = 0.030) and left (p = 
0.012) frontal cortical areas. In addition, these subjects exhibited a 
higher power of the EEG beta1 rhythm in the left occipital (p=0.035), 
parietal (p=0.003), central (p=0.012), frontal (p=0.023) areas and the 
beta2 rhythm in the left parietal (p=0.034) and central (p= 0.05) 
areas, as well as of the EEG theta rhythm in the left occipital 
(p=0.021) and parietal (p=0.034) cortical areas.

Subjects with a high results of the cognitive tests showed lower 

right-sided intrahemisphere coherence of EEG theta range potentials 
(significantly between leads P4-O2, p = 0.031; F4- C4, p = 0.024; T4F4, p= 0.05) than subjects with a poor performance in the tests.

Considering previous results from analysis of the dynamics of the 

EEG alpha rhythm spatial organization [2], the present studies showed 
that higher power of the baseline EEG alpha rhythm is one of the 
factors that determine the dynamic character of EEG coherence.

The high initial values of spectral power of the beta1, beta2 and 

theta ranges in the left cortical areas were the physiological 
prerequisites of the high results of tests requiring logical thinking. 
It is conceivable that a higher power of the EEG beta and theta rhythms 
in the left cortical areas reflects the specific role of the left 
hemisphere in the verbal-logical thinking processes.
