However, the functional role of dynamical rhythmic processes during movements is still not investigated in detail. We used microelectrode recordings to investigate the subthalamic nucleus neuronal activity in 9 patients with Parkinson’s disease during deep brain stimulation surgery. We have shown that the amplitude of the subthalamic nucleus alpha (7–12 Hz) and low-beta (12–20 Hz) activity correlated with motor impairment indices in patients with Parkinson’s disease. Also, we have shown that, in contrast to beta rhythmic activity, the magnitude of alpha activity decreased significantly during motor tests execution. Moreover, the degree of rhythmic activity suppression in the alpha band correlated with the severity of bradykinesia. These results allow us to suppose that, along with beta activities, subthalamic nucleus neuronal alpha activity also participate in motor control of Parkinson’s disease patients.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257551504944">Повышенная осцилляторная бета-активность в базальных ганглиях считается одним из основных электрофизиологических биомаркеров нарушения двигательного контроля при болезни Паркинсона. При этом функциональная роль динамических процессов ритмической активности при выполнении движений до сих пор не до конца изучена. Методом микроэлектродной регистрации мы исследовали ритмическую активность нейронов субталамического ядра у 9 пациентов с болезнью Паркинсона во время проведения нейрохирургических операций для установки систем глубинной стимуляции мозга. Мы показали значимую положительную корреляцию амплитуды альфа- (7–12 Гц) и низкой бета- (12–20 Гц) активности в субталамическом ядре с общими показателями двигательных нарушений у пациентов с болезнью Паркинсона. Также мы показали, что амплитуда ритмической альфа-активности, в отличие от бета-ритмов, значимо снижалась при выполнении пациентами двигательных тестов. Более того, степень снижения альфа-активности напрямую коррелировала с выраженностью симптома брадикинезии. Полученные результаты позволяют предположить, что наряду с бета-активностью в двигательном контроле пациентов с болезнью Паркинсона играет роль также альфа-ритмическая активность нейронов субталамического ядра.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neuronal oscillations</kwd><kwd>bradykinesia</kwd><kwd>microelectrode recordings</kwd><kwd>subthalamic nucleus</kwd><kwd>Parkinson’s disease</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейронная ритмическая активность</kwd><kwd>брадикинезия</kwd><kwd>микроэлектродная регистрация</kwd><kwd>субталамическое ядро</kwd><kwd>болезнь Паркинсона</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Alegre M., Alonso-Frech F., Rodríguez-Oroz M.C., Guridi J., Zamarbide I., Valencia M., Manrique M., Obeso J.A., Artieda J.
