In the same 191 1-hour experiments within 73 students we analyzed the data to see how interhemispheric interactions change when waking up from sleep. Using the Ward hierarchical clustering method, 4 clusters were identified. The average values of behavioral indicators in clusters were estimated, two sets of clusters were compared using Pearson’s chi-square test.</p> <p>It is shown that the pronounced pattern of asymmetry between the hands is the rarest; for the least “sleepy” cluster, alternating awakenings with different hands is characteristic, for the most “sleepy” – the least predictability of patterns over time. It is also shown that the “asymmetric” and “sleepy” clusters never switched each other between falling asleep and waking up, and are more often switched by the remaining two clusters than vice versa.</p> <p>The results obtained can reflect the dynamics of interhemispheric interactions during sleep-wake transitions. It is argued that the differences between the clusters are due to the restructuring of functional connectivity in different ranges of EEG activity.</p></abstract><trans-abstract xml:lang="ru"><p>Ранее на материале множественных засыпаний при выполнении бимануального психомоторного теста с использованием мобильного приложения на смартфоне мы выделили и проинтерпретировали 4 качественно различных паттерна поведенческой активности межполушарных взаимодействий при засыпании. На этих же 73 студентах с 191-часовым экспериментом мы провели анализ данных, чтобы увидеть, как изменяются межполушарные взаимодействия при пробуждении ото сна. С помощью метода иерархической кластеризации по Уорду были выделены 4 кластера. Оценены средние значения поведенческих показателей в кластерах, с помощью критерия хи-квадрат Пирсона сравнили два набора кластеров.</p> <p>Показано, что выраженный паттерн асимметрии между руками является наиболее редким; для наименее “сонливого” кластера характерно чередование рук при пробуждениях, для наиболее “сонливого” – меньшая предсказуемость паттернов во времени. Также показано, что “асимметричный” и “сонливый” кластер никогда не сменяют друг друга между засыпаниями и пробуждениями и чаще сменяются на оставшиеся два кластера, чем наоборот.</p> <p>Полученные результаты могут отражать динамику межполушарных взаимодействий при переходах между сном и бодрствованием. Предполагается, что различия между кластерами обусловлены особенностями перестройки функциональной связности мозга в различных диапазонах ЭЭГ-активности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psychomotor test</kwd><kwd>mobile app</kwd><kwd>asymmetrical sleep</kwd><kwd>hysteresis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>психомоторный тест</kwd><kwd>мобильное приложение</kwd><kwd>асимметричный сон</kwd><kwd>гистерезис</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</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>Шеповальников А.Н., Цицерошин М.Н., Зайцева Л.Г., Гальперина Е.
