Вместе с вышеуказанными нелинейными параметрами исследовалось изменение спектральной плотности мощности ритмических составляющих ЭЭГ: дельта-, тета-, альфа-, бета-ритмов. Изучение фрактальной размерности, экспоненты самоподобия и спектральной плотности мощности ЭЭГ при облучении было связано с возможным изменением данных параметров при депрессии и малой депрессии оператора. В качестве облучателя использовался генератор электромагнитного шумового излучения на транзисторах мощностью 30 мВт в диапазоне частот 5 ГГц. В работе приведено описание методов для расчета нелинейных параметров ЭЭГ, представленных фрактальной размерностью и экспонентой самоподобия. Для определения параметров ЭЭГ: фрактальной размерности, экспоненты самоподобия, спектральной плотности мощности ритмических составляющих при достижении поставленной цели было разработано программное обеспечение на языке Java. Проведено изучение научной литературы, связанной с изменением фрактальной размерности, экспоненты самоподобия, спектральной плотности мощности дельта-, тета-, альфа-, бета-ритмов при депрессии и малой депрессии человека. Регистрация электроэнцефалограмм осуществлялась по схеме «10/20» c использванием электроэнцефалографа «Нейрокартограф» фирмы МБН. Анализируемые отведения ЭЭГ: Fp1, Fp2, T3, T4, Р3, Р4, О1, О2, F3, F4, C3, C4. Результаты работы показали отсутствие четкого депрессивного состояния у оператора при воздействии электромагнитным шумовым излучением, если руководствоваться изменением экспоненты самоподобия, фрактальной размерности и спектральной плотности мощности. Однако при облучении оператора электромагнитным шумовым излучением наблюдалась тенденция изменения параметров, характерная для малой депрессии.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the results of the work aimed at a study of the patterns of changes in the nonlinear electroencephalogram (EEG) parameters, including fractal dimension and self-similarity exponent, when the operator is irradiated with electromagnetic noise radiation. Together with the above-mentioned nonlinear parameters, a change in the spectral power density of the rhythmic components in EEG (delta-, theta-, alpha-, and beta-rhythms) has been studied. Investigation of the fractal dimension, self-similarity exponent, and spectral power density during irradiation was associated with possible changes of the parameters in the case of operator’s depression or minor depression. The radiation source was represented by a transistor electromagnetic-noise generator with the power of 30 mW operating over the frequency range of 5 GHz. The methods for calculation of the nonlinear parameters including fractal dimension and self-similarity exponent have been described. To realize the principal objectives of the work, the Java-based software was developed. The relevant literature demonstrating the changes in fractal dimension, self-similarity exponent, spectral power density of the delta-, theta-, alpha-, beta-rhythms in the case of depression and minor depression has been reviewed. Electroencephalograms were registered according to the “10/20” scheme using the MBN Neurocartograph electroencephalograph. The analyzed leads were Fp1, Fp2, T3, T4, P3, P4, O1, O2, F3, F4, C3, C4. As shown by the results of this work, there is no distinct depressive state of the operator exposed to electromagnetic noise radiation, judging by changes in the self-similarity exponent, fractal dimension, and spectral power density. However, when the operator was irradiated with electromagnetic noise radiation, the observed tendency in variation of the parameters was characteristic for minor depression.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>излучение</kwd><kwd>шум</kwd><kwd>электроэнцефалограмма</kwd><kwd>депрессия</kwd><kwd>человек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation</kwd><kwd>noise</kwd><kwd>electroencephalogram</kwd><kwd>depression</kwd><kwd>human</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Markovà E., Malmgren L.O.G., Belyaev I.Y.
