Abstract(in English) | We had found that characteristic brain activities responding to rhythm variation in music by using magnetoencephalography (MEG). In this study, we investigated whether the brain activities are observed even in simple tone sequences or not. In the experiment, we utilized auditory stimuli consisting of pure tone sequence with 456 ms duration. The tone sequence also included rhythm deviations, with 228 ms and 684 ms durations. Every tone faded-out in 114 ms. Prominent MEG peaks were observed at the offset time of tones with 228 ms duration, suggesting that the responses are caused by perceiving un-expected fading-out. Interaction between (dominant hemisphere) × (instrument experiences) was observed in the peak amplitudes. |
