Source localization of the effects of Persian classical music forms on the brain waves by QEEG

摘要

The aim of this study is investigation of the effects of Persian classical music forms on the brain waves and areas. Main tool was QEEG that registers brain waves. Independent variables include four classical music forms: Pishdaramad, Chaharmezrab, Reng and Avaz that their effects have been investigated on the 12 right handed subjects. The results indicated significant differences in the effects of Pishdaramad form on the theta band while it could affect on different brain areas in comparison with other music forms including the increase of activity in Superior Frontal Gyrus and Precentral Gyrus areas in comparison with noise and Avaz and decrease of activity on Postcentral Gyrus and Supramarginal Gyrus areas in comparison with Chaharmezrab and Reng. The results concluded from rhythmic changes in each of music forms. In other word the increase of rhythm speed can raise the brain activity. Also the results of this study shows important of frontal area during the processing of emotional music.
