Установлено, что у самцов крыс на стабильном этапе первой стадии развития эпилептической системы Эпи активность (число и длительность разрядов в минуту) наиболее выражена в контрлатеральной и ипсилатеральной коре, а у самок крыс ведущие структуры мозга, вовлекаемые в генерацию ЭпА, зависят от фаз эстрального цикла. В фазу диэструс2 у самок ведущей структурой, генерирующей ЭпА, как и у самцов, является контрлатеральная кора, а в фазы проэструс и эструс, которые характеризуются высоким содержанием половых гормонов, у самок наблюдается существенное преобладание ЭпА в латеральном гипоталамусе и дорзальном гиппокампе.</p></abstract><trans-abstract xml:lang="en"><p>In this work, the features of the formation of the epileptic system in male and female rats, depending on the stages of the estrous cycle, were studied on the model of focal cobalt epilepsy. It was found that in male rats at the stable stage of the first stage of development of the epileptic system, Epi activity (the number and duration of discharges per minute) is most pronounced in the contralateral and ipsilateral cortex, and in female rats, the leading brain structures involved in the generation of EpA depend on the phases of the estrous cycle. In the diestrus2 phase, in females, the leading structure generating EpA, as in males, is the contralateral cortex, and in the proestrus and estrus phases, which are characterized by a high content of sex hormones, in females there is a significant predominance of EpA in the lateral hypothalamus and dorsal hippocampus.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гендерные различия</kwd><kwd>самцы крыс</kwd><kwd>самки крыс</kwd><kwd>эстральный цикл</kwd><kwd>эпилептическая система</kwd><kwd>кобальтовая эпилепсия</kwd><kwd>ЭЭГ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gender differences</kwd><kwd>male rats</kwd><kwd>female rats</kwd><kwd>estrous cycle</kwd><kwd>epileptic system</kwd><kwd>cobalt epilepsy</kwd><kwd>EEG</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания (проект № 0521-2019-0007) «Разработка средств лечения эпилепсии, болезни Паркинсона и аутизма на основе новых данных патогенеза заболеваний».</funding-statement><funding-statement xml:lang="en">This work was carried out as part of the state assignment (project No. 0521-2019-0007) "Development of treatments for epilepsy, Parkinson's disease and autism based on new data on the pathogenesis of diseases".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Карлов В.А.
