ABSTRACT
Music is universal and is present in all cultures and capable of conveying emotions irrespective of verbal content. The present study was conducted to understand the impact of music on brain with real-time monitoring of EEG changes in patients with moderate-to-severe neuronal dysfunction. In this prospective study, adult patients who had brain trauma and unconscious were considered for the study. Two different music pieces were selected to give music experience. One is Revathi raga with Upanishads' stands. Another is Ragamalika, an instrumental music piece comprising various Carnatic ragas. For EEG recording, electrode montage was done according to international 10-20 system. After music experience, again EEG recording was done without music. Comparison of EEG activity during different musical pieces was not considered. A total of six adults were studied. During the time of music session, there was no change in the EEG at other channels, but at T6 electrode, EEG did not have the arc like fast theta. That fast theta was disappeared in T6 electrode and it was suppressed like a contralateral sided electrode. After the music session (post music session), the EEG is back to baseline, but the temporal arc like fast theta speed was decreased (2-4 seconds per page). In this case series, we observed that in one case, there was appearance of slow activity in EEG. However, there is a need for larger studies to confirm these findings.
