Abstract:Music has been present throughout human evolutionary history and is an intimate part of the human form of life which can elicit strong and a wide range of emotions. Recent evidence suggests that during social situations and prolonged natural stimulation, synchronization of individuals’ brain activity may occur in a multitude of brain areas during audio and visual stimuli. This study analyzes the Magnetoencephalographic (MEG) based music emotion by combining these two concepts of inter-subject synchrony and music stimulation. The dataset used in this study is already preprocessed using the spatiotemporal signal space separation (tSSS) method and can be immediately used to perform analysis and experiments. Inter-subject correlation analysis and correlation component analysis is used to show that brain responses synchronize among subjects to different parts of music stimulation. Further, Spearman correlation coefficient is computed to verify negative correlation between the standard deviation of subject’s emotions and averaged inter-subject synchrony, which consequently means that when brain signals synchronize across subjects, it is due to the same emotional perceptions that the subjects felt to the song.
