Materials and methods. To model chronic focal epilepsy, we used topical applications of cobalt on the sensorimotor zone of the rat cortex. The effect of lacosamide (20 mg/kg) on the cobalt-induced epileptiform activity was analyzed in parallel with with the monitoring of spectral-coherent changes in the brain during the development of the epileptic system (ES). Results. In the first 30 minutes after the administration, lacosamide briefly enhanced the EрA in the hippocampus and ipsilateral cortex, and also strengthened the cortical-hippocampal (at stage 1) and cortical-hypothalamic connections (at stage 2). Two hours after the drug administration, a decrease in EрA was observed at stages 1 and 2 of the ES development, especially in the contralateral cortex and hippocampus. At all frequency ranges, the level of the inter-center connections decreased (most pronounced in the cortical-hippocampal links). Conclusion. The effect of lacosamide on EрA in the rat brain with cobalt-induced epileptogenic focus is characterized by a decrease in EрA, two hours after the drug administration. This effect is most expressed in the cortex and hippocampus, and is accompanied by a decrease in the level of the corticalhippocampal connections.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – изучение влияния лакосамида на эпилептиформную активность (ЭпА) и динамику структурно-функциональных связей с развитием эпилептической системы в структурах мозга крыс с кобальт-индуцированной хронической эпилепсией. Материалы и методы. Моделирование хронической фокальной эпилепсии проведено с помощью аппликации кобальта на сенсомоторную зону коры крыс. Проведен анализ влияния лакосамида (20 мг/кг) на ЭпА и спектрально-когерентный анализ на двух стадиях развития ЭС в структурах мозга. Результаты. Лакосамид в первые 30 мин. после введения кратковременно усиливает ЭпА в гиппокампе и ипсилатеральной коре, а также корково-гиппокампальные (на 1-й стадии) и корково-гипоталамические связи (на 2-й стадии). Снижение ЭпА наблюдается через 2 ч после введения препарата на 1-й и 2-й стадиях развития ЭС, с наибольшим влиянием в контрлатеральной коре и гиппокампе. Для всех диапазонов частот наблюдается снижение уровня межцентральных связей, с наибольшей выраженностью для корково-гиппокампальных. Заключение. Влияние лакосамида на ЭпА мозга крыс с кобальт-индуцированным эпилептогенным очагом характеризуется снижением ЭпА через 2 ч после введения преимущественно в коре и гиппокампе, что сопровождается снижением уровня корково-гиппокампальных связей. В настоящей работе впервые на хронической модели эпилепсии на основе когерентного анализа выявлены особенности эффектов лакосамида на разных стадиях формирования ЭС, что может быть использовано для оптимизации лечения эпилепсии.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лакосамид</kwd><kwd>эпилепсия</kwd><kwd>эпилептическая система</kwd><kwd>ЭЭГ</kwd><kwd>пароксизмальная активность</kwd><kwd>кобальт-индуцированная эпилепсия</kwd><kwd>крысы</kwd><kwd>спектрально-когерентный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Lacosamid</kwd><kwd>epilepsy</kwd><kwd>epileptic system</kwd><kwd>EEG</kwd><kwd>paroxysmal activity</kwd><kwd>cobalt-induced epilepsy</kwd><kwd>rats</kwd><kwd>spectral-coherent analysis</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">Карлов В.
