In this regard, the present study was aimed to investigate the age-related characteristics of the electrical activity of the brain depending on this polymorphism and long-term intellectual training. We examined EEG power indicators in subjects of the younger (YG, 18–35 years, N = 261) and older (OG, 55–80 years, N = 142) age groups. According to the intellectual richness of the professional activity environment, the subjects were divided into scientists (SA) and those engaged in non-scientific activities (NSA). All subjects were genotyped for the STin2VNTR polymorphism of the serotonin transporter gene. It was found that the power of delta-beta1 rhythms in older carriers of the 10/10 and 12/12 genotypes was opposite in SA and NSA groups (in the SA group 10/10 &gt; 12/12, in the NSA 12/12 &gt; 10/10) while similar effects in young subjects were absent. In the absence of cognitive training, genetic differences were determined by an age-related decrease in the power of delta-alpha3 rhythms in carriers of the 10/10 genotype with no age-related differences in carriers of the 12/12 genotype, suggesting the resistance of the 12/12 genotype to age-related changes. In contrast, under cognitive training conditions, there were no age differences in the 10/10 genotype, and a decrease in power was observed in the 12/12 genotype, suggesting an effect of cognitive training on both homozygous genotypes. The decrease in power observed for the 10/10 NSA and 12/12 SA genotypes appears to have different physiological significance, since it was accompanied by changes in attentional efficiency only in the NSA group. The work shows for the first time that the background EEG features associated with the STin2VNTR polymorphism of the serotonin transporter gene in elderly people are under the modulating influence of long-term cognitive training, determined by the specificity of professional activity.</p></abstract><trans-abstract xml:lang="ru"><p>Ранее нами были выявлено, что ассоциации между полиморфизмом STin2VNTR гена транспортера серотонина и когнитивными характеристиками при старении зависят от интеллектуальной среды профессиональной деятельности. В связи с этим настоящее исследование направлено на изучение возрастных особенностей электрической активности мозга в зависимости от данного полиморфизма и длительного интеллектуального тренинга. Мы исследовали показатели мощности ЭЭГ у участников эксперимента младшей (МВГ, 18–35 лет, N = 261) и старшей (СВГ, 55–80 лет, N = 142) возрастной групп. По интеллектуальной насыщенности среды профессиональной деятельности участники эксперимента подразделялись на ученых (НД) и не занимающихся научной деятельностью (ННД). У всех участников эксперимента проведено генотипирование полиморфизма STin2VNTR гена транспортера серотонина. Обнаружено, что показатели мощности дельта-бета1 ритмов у носителей 10/10 и 12/12 генотипов были противоположны в группах пожилых НД и ННД (в группе НД 10/10 &gt; 12/12, в ННД 12/12 &gt; 10/10) при отсутствии аналогичных эффектов у молодых участников эксперимента. В отсутствии когнитивного тренинга генетические различия определялись возрастным снижением мощности дельта-альфа3 ритмов у носителей генотипов 10/10 при отсутствии возрастных различий у носителей генотипа 12/12, что позволяет предположить устойчивость генотипа 12/12 к возрастным изменениям. В противоположность этому в условиях когнитивного тренинга возрастные различия отсутствовали у генотипа 10/10, а снижение мощности наблюдалось у генотипа 12/12, что позволяет предполагать эффект когнитивного тренинга в отношении обоих гомозиготных генотипов. Снижение мощности, наблюдаемое для генотипа 10/10 ННД и 12/12 НД, по-видимому, имеет различное физиологическое значение, поскольку сопровождалось изменениями эффективности внимания только в группе ННД. В работе впервые показано, что ассоциированные с полиморфизмом STin2VNTR гена транспортера серотонина особенности фоновой ЭЭГ у пожилых людей находятся под модулирующим влиянием длительного когнитивного тренинга, обусловленного спецификой профессиональной деятельности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>EEG power</kwd><kwd>aging</kwd><kwd>cognitive training</kwd><kwd>intellectual load</kwd><kwd>STin2VNTR polymorphism of the serotonin transporter gene</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>мощность ЭЭГ</kwd><kwd>старение</kwd><kwd>когнитивный тренинг</kwd><kwd>интеллектуальные нагрузки</kwd><kwd>полиморфизм STin2VNTR гена транспортера серотонина</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>122042700001-9</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Вольф Н.В., Приводнова Е.Ю.
