Evaluation the Relationship between EEG Pattern and Overt Aggressive Behavior

There are very studies in determine the criteria for diagnosis and assessment of aggression. The aim of this study was study of aggressive subject’s brain wave activity in compare with healthy subjects by qEEG. The research method was contrastivedescriptive over which some 30 people of aggressive Persons compared and contrasted with some 30 nonaggressive persons were demographically similar to aggressive group. The artifact free EEG epoch was analyzed by fast Fourier transformation (FFT) and Power values of particular frequency bands (delta, theta, alpha and beta) were observed on the brain Regions. Results and Results of variance analysis showed that aggressive subjects theta activity in frontal, central, Parietal and temporal areas is lower than normal subjects. In addition increase in beta activity in frontal, central, Parietal and temporal areas in compare with nonaggressive subjects. These results suggest the disorder change the brain waves activity.
