The aim of this study was to investigate the peculiarities and localization of the current source of α- and θ-rhythms accompanying competition and cooperation with another player, as well as solo figure building in a computer game. The sample included 42 volunteers (24 females) aged from 18 to 47 years. The analysis of differences in the current source density registered with a 127-channel EEG in different game conditions was performed in the eLoreta software. The θ-rhythm spectral density was greater during competition than during cooperation and most prominent in the anterior cingulate cortex and medial prefrontal cortex. According to the literature on functional correlates of the θ-rhythm, it can be suggested that the greater increase in the frontal-midline θ-rhythm detected during competition may be related to focused attention and cognitive control processes. The source density of α-rhythm in the parietal and visual cortex areas during interactive game modes (cooperation and competition) was lower compared to the solo mode. During cooperation the α-rhythm spectral density was lower compared to the competition mode. The greatest decrease of α-rhythm spectral density in the cooperation mode was consistent with the concept of relation between α-rhythm decrease and the processes of understanding the other person's intentions.
