Предлагаемый подход основан на анализе динамики мышц лица испытуемого по видео. В пилотном исследовании приняли участие 18 здоровых добровольцев.

Показано, что пол испытуемого, статус экрана (пустой, собственное/чужое лицо), номер пробы связаны с различиями в мимической активности лица и могут выступать искомыми ковариатами. Сделан вывод, что анализ динамики мимической активности по видео с открытыми глазами может быть дополнительным методом в нейрокогнитивных исследованиях для изучения имплицитных когнитивных процессов, связанных с восприятием изображения себя и другого, в парадигме функционального покоя.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of a study aimed at finding covariates to account for the activity of implicit cognitive processes in conditions of functional rest of the subjects and during them being presented their own or someone else’s face in a joint analysis of EEG experiment data. The proposed approach is based on the analysis of the dynamics of the facial muscles of the subject recorded on video. The pilot study involved 18 healthy volunteers. In the experiment, the subjects were sitting in front of a computer screen and performed the following task: sequentially closed their eyes (three trials of 2 minutes each) and opened them (three trials of the same duration between periods of closed eyes) when the screen was either empty or when it was showing a video recording of their own face or the face of an unfamiliar person of the same gender as the participant. EEG, ECG and a video of the face were recorded for all subjects. In the work a separate subtask of the study was also addressed: validating a technique for assessing the dynamics of the subjects’ facial muscle activity using the recorded videos of the “eyes open” trials to obtain covariates that can be included in subsequent processing along with EEG correlates in neurocognitive experiments with a paradigm that does not involve the performance of active cognitive tasks (“resting-state conditions”). It was shown that the subject’s gender, stimulus type (screen empty or showing own/other face), trial number are accompanied by differences in facial activity and can be used as study-specific covariates. It was concluded that the analysis of the dynamics of facial activity based on video recording of “eyes open” trials can be used as an additional method in neurocognitive research to study implicit cognitive processes associated with the perception of oneself and other, in the functional rest paradigm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейрокогнитивные исследования</kwd><kwd>свое и чужое лицо</kwd><kwd>ЭЭГ-корреляты</kwd><kwd>ковариаты</kwd><kwd>имплицитные когнитивные процессы</kwd><kwd>самовосприятие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neurocognitive studies</kwd><kwd>own and other face</kwd><kwd>EEG correlates</kwd><kwd>covariates</kwd><kwd>implicit cognitive processes</kwd><kwd>selfperception</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>Data collection and processing were supported by the Russian Science Foundation, grant No. 22-15-00142 “fMRI and EEG correlates of focus on oneself as a predisposition factor to affective disorders”.
