| Abstract(in English) | The daily behavior of the person is affected by the subjective preference. Recently the study on the electroencephalogram (EEG) which is related to the preference has been started. Most of the studies so far have been focus on the visual preference. The studies clarify that prefrontal theta and occipital gamma bands are involved in the preference. On the other hand, music has a relaxation effect, and can reduce our stress. Recently musical therapy is used for the functional training for dementia, and the people experiencing disability. The effect is maximized when they listen to the favorite music. Thus to know the individual's music preference is also important. In the present study, the music preference was studied using electroencephalogram (EEG). Five healthy males (23.5±0.5 years) participated in the experiment. They listened to the music EEG for 30-35 sec, thought for 10 sec, and then decided the preference in four levels. After the preference, there was a rest for 35 sec. A subject listened to twenty pieces in 5-8 genres. EEG was recorded throughout the experiment. It was analyzed using fast Fourier transform. The mean power levels of theta (4-8 Hz), alpha (8-12 Hz), beta (12-30 Hz), and gamma (30-50 Hz) were calculated while the subject listened to the music, and while they thought the choice. In addition, cross-validation of the power levels in one dimension was done using the linear discriminant analysis (LDA). In the preference thinking period, the averaged power of the prefrontal theta band at "like" choice was higher than at "dislike" choice. The difference was not significant. On the other hand, both during listening to music and preference thinking period, the averaged power of the occipital gamma band tended to be higher at "dislike" choice than at "like" choice. The difference was not significant. The cross-validation result showed that the three highest correct answer rates were obtained using the occipital gamma, the prefrontal alpha, and the occipital gamma bands. Hence, the occipital gamma bands may participate in "like" and "dislike" emotion. |
