Existing studies show mixed results about the impact of internet use on attention, cognitive control, and other cognitive functions.</p> <p><bold><italic>AIM:</italic></bold> To evaluate the components of the event-related potentials (ERPs) P300 and N2 in practically healthy adolescents aged 16–17 years with varying levels of internet addiction risk and a stable pattern of internet addiction (IA).</p> <p><bold><italic>MATERIAL AND METHODS:</italic></bold> The study involved healthy young people aged 16–17 years old who attended Simferopol city school.The Chen Internet addiction scale was used to access the level of IА in the Russian version of V.L. Malygin and K.A. Feklisov. The registration of the ERPs P300 and N2 components was carried out with the use of an electroencephalograph “Neuron-Spectrum-4/VPM” (Neurosoft, Russia). An auditory oddball paradigm was used.</p> <p><bold><italic>RESULTS:</italic></bold> In young men, no differences in the N2 and P300 latency were observed across the groups. There was an elongation of the N2 latency in the frontal and central regions of the brain in girls with a proclivity for IА, indicating a slower primary identification and classification of stimuli. In girls with a stable pattern of IА, there was an increase in the N2 latency in the central, left frontal, and right medial temporal regions, as well as an increase in the P300 latency in the frontal, central, and parietal right parts of the brain, compared to girls with minimal risk of IА, indicating the need for more time to identify the stimulus and make a decision.</p> <p><bold><italic>CONCLUSIONS:</italic></bold> An increase in the N2 latency has already been reported in girls with a proclivity for IА, which can be used to predict the development of IА and for prevention.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> В связи с популяризацией цифровых технологий люди стали больше времени проводить в Интернете. Имеются неоднозначные данные о влиянии использования Интернета на внимание, когнитивный контроль и другие когнитивные функции.</p> <p><bold>Цель. </bold>Провести оценку компонентов слухового вызванного потенциала Р300 и N2 у практически здоровых подростков в возрасте 16–17 лет с различным риском возникновения интернет-зависимого поведения и устойчивым паттерном интернет-зависимости (ИЗ).</p> <p><bold>Материал и методы.</bold> В исследовании участвовали подростки 16–17 лет (<italic>n</italic>=55) г. Симферополя. Уровень ИЗ оценивали по шкале Чена в адаптации В.Л. Малыгина, К.А. Феклисова. Регистрацию компонентов Р300 и N2 проводили на электроэнцефалографе «Нейрон-Спектр-4/ВПМ» («Нейрософт», Россия), использовали парадигму oddball.</p> <p><bold>Результаты.</bold> У юношей не выявлено различий латентных периодов N2 и Р300 между группами. У девушек со склонностью к возникновению ИЗ отмечалось удлинение латентного времени (ЛВ) N2 в лобных и центральных отделах головного мозга, что отражает более медленное первичное опознание и классификацию стимулов. У девушек с устойчивым паттерном ИЗ наблюдалось увеличение ЛВ N2 в центральных, лобном слева и средневисочном справа отделах головного мозга и удлинение ЛВ Р300 в лобном, центральном и теменном справа отделах головного мозга по сравнению с девушками с минимальным риском ИЗ, что свидетельствует о необходимости большего времени для идентификации ими стимула и принятия решения.</p> <p><bold>Заключение.</bold> Увеличение ЛВ N2 наблюдалось уже у девушек со склонностью к возникновению ИЗ, что может быть использовано для прогноза развития и для профилактики ИЗ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>auditory event-related potentials</kwd><kwd>the internet аddiction</kwd><kwd>adolescents</kwd><kwd>Chen Internet addiction scale</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слуховые вызванные потенциалы</kwd><kwd>Р300</kwd><kwd>N2</kwd><kwd>подростки</kwd><kwd>интернет-зависимость</kwd><kwd>шкала Чена</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский фонд фундаментальных исследований</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap></funding-source><award-id>20-013-00060</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">ФГБУН Федеральный исследовательский центр комплексного изучения Арктики имени академика Н.П.
