The most of confl ictogenic factors should be concerned as open or latent aggression. Thus, “aggressive” computer games can be used as an experimental model for study brain mechanisms of confl ictness. The aim of this study was inves tiga tion of gender-depended role of anterior cortex areas in regulation of teenage confl ictness. According to Utkin’s confl ictness questionnaire test results subjects were divided into 4 groups: boys and girls with a high or low level of potential confl ictness. The infl uence of aggressive computer gameplay was investigated. The brain visual evoked potentials were recorded from frontal and orbito-frontal cortex before and after playing the computer game. The analysis of obtained data has shown that, as a result of gameplay, the boys’ brain anterior cortex activity increased, which correlated with decreasing level of confl ictness. In the group of girls the activity of anterior cortex areas was decreased. However, there was a difference between frontal and orbito-frontal areas activity depended on the initial confl ictness level. Initially high level of orbito-frontal activity was recorded at girls with high confl ictness. The aggressive computer gameplay reduced orbito-frontal activity that caused decrease of confl ictness level. Non-confl icting girls had initially high frontal activity which decreased through aggressive gameplay. It is connected with weakening of cortex control and corresponding increase of confl ictness level.
