Stimulus positions were manipulated through interaural intensity differences. Evoked responses to the signal's onset and offset were maximally suppressed when the masker position matched the signal’s starting and ending points, respectively. As the distance increased, the responses partially recovered, indicating a spatial release from masking. The maximum suppression of the motion onset response occurred when the lateral or central masker was located at the end of the movement trajectory. Despite complete or partial suppression of the GFP, the listeners were able to localize the test signals under masking conditions. However, the perceived signal trajectories shortened, and their perceived positions shifted away from the masker. The GFPs were more susceptible to energetic masking, while behavioral responses were more robust in recognizing motion, as they relied on the activity of broad neural networks involved in the integration of sensory information over a longer time period.</p></abstract><trans-abstract xml:lang="ru"><p>Исследовано действие одновременной маскировки при разном угловом расстоянии между стационарными маскерами и сигналами с отсроченным началом движения на воспринимаемое положение концов траекторий сигналов и на величину мощности глобального поля (МГП) вызванных ответов в энцефалограмме. Положение стимулов задавали при помощи межушных различий по интенсивности. Вызванные ответы на включение и выключение сигнала были максимально подавлены при совпадении положения маскера с началом и концом траектории сигнала соответственно, а при увеличении расстояния частично восстанавливались, что соответствует пространственному освобождению от маскировки. Максимальное подавление ответа на начало движения происходило, когда латеральный или центральный маскер располагался в конце траектории движения. Несмотря на полное или частичное подавление МГП отдельных ответов, в условиях маскировки сохранялась способность локализовать тестовые сигналы, но их траектории укорачивались, а воспринимаемое положение смещалось от маскера. МГП сильнее подвержены энергетической маскировке, а поведенческие ответы более устойчивы в распознавании движения, так как опираются на активность широких нейронных ансамблей, обеспечивающих интеграцию сенсорной информации на более длительном временном отрезке.</p></trans-abstract><kwd-group xml:lang="en"><kwd>auditory evoked potentials</kwd><kwd>global field power</kwd><kwd>motion onset response</kwd><kwd>spatial masking</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слуховые вызванные потенциалы</kwd><kwd>мощность глобального поля</kwd><kwd>ответ на начало движения</kwd><kwd>пространственная маскировка</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Госпрограмма 47 ГП «Научно-технологическое развитие Российской Федерации» (2019–2030)</institution></institution-wrap><institution-wrap><institution xml:lang="en">State Program 47 GP "Scientific and Technological Development of the Russian Federation" (2019–2030)</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Litovsky R.Y.
