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:The aim of this study was to evaluate the efficacy of electrical stimulation of the brain cortex on reducing and improving behavioral problems in children with ADHD disorders aged 7-12 years.Method: 22 children from 7 to 12 years of age whose attention deficit hyperactivity disorder was confirmed by a psychologist or psychiatrist, or diagnosed with Clinical interview based on DSM-V diagnostic criteria and Parent Conners Test, Were divided into two experimental and control groups. Before the treatment, CBCL questionnaire was performed for children in both groups. The experimental group was treated by transcranial direct current stimulation (tDCS) at FC3 and FC4 sites for 15 days. CBCL test was performed after treatment and again at intervals of two months after the completion of treatment.Results: Analysis of the research data with central indicators, Average and standard deviations, and variance with repeated measurements showed a significant difference between the behavioral Features of children under treatment and the children of the control group.Conclusion: transcranial direct current stimulation (tDCS) in the FC3 and FC4 regions can help improve the behavioral Features of hyperactive children.

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.

Introduction: The main aim of present study was to compare the effect of Neurofeedback training and Neurofeedback along with cognitive rehabilitation on ADHD children’s improvement. Method: To do so, 20 elementary students with ADHD were selected among Tehran clinics’ clients through purposive sampling. For assessing attention, TOVA test was conducted by all subjects as continues performance test. Subjects were divided in to two groups; 10 subjects received Neurofeedback training alone and another group trained Neurofeedback along with cognitive rehabilitation. Training session were conducted for 10 weeks; each week three sessions. Data were analyzed using Analysis of Covariance (ANCOVA). Findings: The results showed that effect size of Neurofeedback along with cognitive rehabilitation was higher than Neurofeedback training alone on impulsivity problems’ reduction. Conclusion: The results of this study showed that Neurofeedback can decrease signs of ADHD and the effect of Neurofeedback can be more obvious if cognitive rehabilitation is added.

Introduction: The main objective of this study was the assessment of neurofeedback and neuro-biofeedback training’s efficacy in decreasing Obsessive Compulsive Disorder’s symptoms. Method: This study was a quasi-experimental one with pre-test and post-test plan. The sample included 12 OCD patients who were randomly selected. The research instrument was Madzly Inventory. First the subjects had pre-test and then, they were randomly placed in three groups: Two experimental groups who had Neurofeedback or Neuro-biofeedback training, and one control group who only received medicine. The experimental groups had 30 treatment sessions for 10 weeks. In order to analyze the data, the covariance multivariate analysis was used. Findings: The results showed significant changes in symptoms’ reduction of OCD in neurofeedback training group in comparison to the control group (p
