Abstract
This study is devoted to the search for influential markers of optical and acoustic communication channels on the interlocutors in face-to-face and back-to-back communication. The rhythm patterns in different frequency ranges, including the projection of facial muscles on electroencephalogram and electromyogram data, are analyzed. The patterns of the electroencephalogram rhythms are shown to have similar and distinctive features in different communication modes. The maximum number of distinctions between various communication modes with interlocutors situated back-to-back was observed in Δ and γ rhythms in the brain. When the interlocutors are positioned face-to-face, a powerful nonverbal component increases the power of β and γ rhythms and levels out the distinctions between different communication modes. The frontal (F7 and F8) and occipital (O1 and O2) areas of the brain are the most informative and demonstrate significant distinctions between different communication modes at different interlocutor positions relative to each other.
