One of the possible reasons of a shortage of data in literature on age change of neurodynamic parameters of women within reproductive stage ontogenesis is, against the background research of a leading age factor, ignoring influence of the OMC factor stage.
The work discovers a gradual decrease of amplitude- power status of electroencephalography in females from the beginning of reproductive period of ontogenesis towards its end. This decrease is prevalent in slow rhythms spectra and is accompanied by parallel amplification of the frequency of delta- and theta-components of electroencephalography, as well as the local increase of the amplitude of beta H- and beta B-rhythms spectra in frontal scalp sections.
The changes of 272 EEG parameters in 252 women and 97 men during the period of life of 16 to 45 years in increments of one month were investigated. Correlation analysis and approximations were used. Ontogenetic regression of amplitude and power amplitude and power of alpha, theta, delta, but not beta rhythms predominantly in the right posterior cortex leads in women was more regressive than in men was shown. Overall ontogenetic tendency to fall to the nonlinear amplitude and power of EEG rhythms with age is reproduced in both sexes. Frequency of rhythms in the course of ontogeny, as a rule, was the compensatory increase. So, in neurologically healthy men and women differently achieved the same goal - adaptive response of the brain to age conversion.
The falling of the amplitude size of human rhythms REG and EEG in human ontogenesis with prevalence of negative correlations between REG indicators and age at males is establishe. According to EEG the regularity amplifies at the rate of rhytm "beta-alpha-tete-delta" and more at males
