Background: Nowadays, the study of neurological infrastructure of personality traits has a special place in neuropsychological research. According to Eysenck, the correlation between personality and behavior is the result of individual differences in the brain function. The purpose of the present study was to investigate the frontal EEG asymmetry according to neuroticism and extraversion dimensions.Methods: The statistical population of the present study was all male students of Payame Noor University of Tehran, who studied in the academic year of 1963-96. Based on the final scores of distribution in two dimensions of extroversion and neuroticism, four groups (extroverts, introverts, neuroticism and emotional stability) with 25 subjects were selected. The subjects completed the Eysenck Personality Questionnaire- Revised, Waterloo Handedness and footedness Questionnaires-Revised, and their eyedness was assessed, then the electrical activity of the brain of the subjects was recorded through EEG from different points on the scalp. Results: The findings of the study show that there is no significant difference between the four groups in the right frontopolar (FP2), right middle frontal (F4), right lateral frontal (F8) and right frontal cortex (RF) in alpha activity. There is a significant difference between the left frontopolar (FP1), left middle frontal (F3), left lateral frontal (F7) and left frontal cortex (LF) between the four groups (P<0.01); as alpha wave activity on left regions in neurotic and introverted individuals is more than emotional stable and extroverted subjects. Conclusion: In general, the findings of the present study strengthen the relationship between personality dimensions and frontal EEG asymmetry.

Introduction: Computer games, due to their expansion and popularity, have become one of the favorite topics of researchers in the field of brain and its function. The aim of this study was to evaluate computer skills in computer games and to examine the two networks of anterior and posterior attention. Method: The present study is a quasi-experimental method and two groups of profetional and notice participate in computer games. participant in both groups responded to the task during the EEG recording. The components studied in this study were the P1 component in the posterior attentional network and the posterior area and the PP2 component in the anterior attentional network and pre-forehead areas. Results: The results showed that the two profetional groups and so on are different in response to computer games and the notice group showed more activity in the face of stimuli. While the profetional group performed better and used both attention networks simultaneously. The results also showed that the two anterior and posterior attentional networks act differently in the face of stimuli, and the anterior network is more active in focusing attention. Conclusion: According to the obtained results, it can be said that computer games are associated with less activity and better but non-specialized performance in the brain, and this difference can be clearly seen in the anterior attention network.

Introduction: This study aimed to evaluate and compare the effectiveness of music therapy and neurofeedback, as two non-invasive methods, on the reduction of pain in patients with somatic complaints. Method: The samples of the study include 86 students of Payame Noor University of Tehran who were selected on the basis of the complaints of physical pain and medical diagnosis. All participants completed measures of pain, physical symptoms, and Takata responded Sakata. Then they were divided into two intervention groups and received either music therapy or neurofeedback. The data were analyzed through running Covariance analysis. Findings: The results indicated that neurofeedback, compared to music therapy, had significant impact on reducing the patients' physical symptoms, especially on their headache. Conclusion: According to the results it could be argued that neurofeedback due to its effect on brain waves can be effective for adjusting and reducing psychosomatic pains.
