Therefore, the aim of the study was to study the processes of perception of rhythmic light incentives and induced electrical activity of the visual cortex during a computer load. The study was conducted with the participation of clinically healthy students ( n = 182), who determined the critical fusion frequency of flashes and recorded rhythmic cortical evoked visual potentials during a computer-assisted visual load. To assess the nature and duration of use of computer students, as well as determining the presence and severity of computer dependency, a survey was conducted. Various types of perception of light flashes and changes in the rhythm assimilation reaction under the influence of a computer load are revealed. The data are discussed taking into account the rhythmic processes of the brain. A conclusion is drawn about the weakened, stable and strengthened types of response of oscillatory neural mechanisms to computer visual loads.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность разработки и совершенствования методов исследования функционального состояния пользователей компьютерными технологиями нарастает параллельно с ростом их негативного воздействия на основные мишени - зрительную и нервно-психическую функции. Поэтому целью исследования стало изучение процессов восприятия ритмических световых стимулов и вызванной электрической активности зрительной коры в ходе компьютерной нагрузки. Исследование было проведено с участием клинически здоровых студентов ( n = 182), у которых определены критическая частота слияния мельканий и зарегистрированы ритмические корковые вызванные зрительные потенциалы в ходе компьютерной зрительной нагрузки. Для оценки характера и продолжительности использования студентами компьютера, а также определения наличия и выраженности компьютерной зависимости было проведено анкетирование. Выявлены различные типы восприятия световых мельканий и изменений реакции усвоения ритма под воздействием компьютерной нагрузки. Данные обсуждены с учетом ритмических процессов головного мозга. Сделан вывод об ослабленном, стабильном и усиленном типах реагирования нейронных механизмов на компьютерные зрительные нагрузки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>critical flicker fusion frequency</kwd><kwd>rhythm assimilation reaction</kwd><kwd>computer load</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>критическая частота слияния мельканий</kwd><kwd>реакция усвоения ритма</kwd><kwd>компьютерная нагрузка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Basar E., Basar-Eroglu C., Karakas S., Schurman M.
