Abstract
The aim of the present study was to investigate the prominence of type of brain oscillations in processes combined with attention voluntarily directed to emotionally significant stimuli. An indigenously designed experiment paradigm was conducted on specific class of healthy subjects using a series of audio and video clippings as stimuli. Each of the clippings was associated with one of the three different types of emotions namely sad, calm and excitation. Changes in peak of power spectrum and Inter hemispheric coherences showed an enhanced alpha rhythm dynamics compared to gamma rhythms. Results from repeated measures using T-test and ANOVA showed that Alpha rhythm dynamics play more possible functional roles as compared with gamma rhythms. The fact that the study conducted on a similar class of subjects increases the chance of nullification of factors such as age, gender, educational and societal status which also influences the presence of alpha.
