As reported in the literature, the high-frequency oscillations (80-500 Hz) are highly informative markers of an epileptic focus. In this review, we analyze features of high-frequency activity associated with the epileptiform activity, and its relation to the seizure onset range. Further study of high-frequency bioelectric activity of the brain is of interest to researchers and clinicians, and may improve the EEG differential diagnosis of epilepsy.</p></abstract><trans-abstract xml:lang="ru"><p>Современные исследования гамма-ритма свидетельствуют о том, что гамма-активность включает в себя как гамма-диапазон (стандартная ЭЭГ), так и высокочастотные (100-1000 Гц) и сверхчастотные осцилляции (более 1000 Гц), регистрируемые электрокортикографией. В обзоре литературы последних лет показано, что высокочастотные осцилляции (80-500 Гц) являются высокоинформативными маркерами эпилептического очага. Авторами проанализированы результаты исследований особенностей ассоциированности высокочастотной активности с эпилептиформной активностью, ее роли в запуске эпилептического приступа, частого совпадения с областью запуска эпилептического припадка. Дальнейшее изучение высокочастотной биоэлектрической активности головного мозга представляет интерес для исследователей и клиницистов с целью совершенствования электроэнцефалографической дифференциальной диагностики при эпилепсии.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гамма-ритм</kwd><kwd>гамма-осцилляции</kwd><kwd>высокочастотная активность</kwd><kwd>эпилептический очаг</kwd><kwd>область запуска эпилептического припадка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gamma rhythm</kwd><kwd>gamma oscillations</kwd><kwd>high-frequency activity</kwd><kwd>epileptic focus</kwd><kwd>seizure onset</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">Авакян Г.
