Assessment of relationship between asymmetries EEG waves at baseline with Eysenck Personality traits

Abstract:Aim: asymmetry of brain hemispheres activities, one of the wonderful features is the organization of human brain activity. aim of this study is Assessment of relationship between asymmetries EEG waves at baseline with Eysenck Personality traits.Materials and Methods:The study design was cross-sectional study that was conducted in Sabzevar. The target population was all students of Payam Noor University of Sabzevar in the school year (93-92). 33 students (17 male and 16 female) were selected using available sampling method. Research instrument included electroencephalography, Eysenck Personality Questionnaire, General Health Questionnaire and Positive-Negative Affect Questionnaire. Data were analyzed using descriptive statistics and Pearson correlation. Results:The results of the EEG waves at rest revealed asymmetric temporal and parietal lobes activity in the extroverts and asymmetric temporal lobe activity in introverts. Other findings of the research were that in baseline, there was a significant relationship between asymmetry temporal lobe activity in the neurotic-stable personality trait. Conclusion:Overall, the findings of this study suggest that the type of personality affects the activity of certain brain areas
