| Abstract(in English) | Music perception has an important role in developments of human cognitive function. The relationship between music and brain have been well investigated such as cortical entrainment to periodic tune and periodic beat. It has also been reported that the cerebral cortex more strongly responded to the periodic rhythm of unfamiliar music than to that of familiar music. However, it is unclear whether or not the cerebral cortex entrains to natural music, aperiodic stimuli, and how the response, if present, is influenced by the familiarity of music. To better understand the mechanism of music perception, we investigated by electroencelphalography (EEG) the cortical entrainment to natural music, and the relationship between cortical response and familiarity of music, using single-tone melody as simple natural stimuli. The cross-correlation function averaged across trials, channels, and subjects showed a peak at time lags around 150 ms. Furthermore, the value of cross-correlation function at the peak while listening to unfamiliar music was larger than listening to familiar music. Our findings suggest that at a low-frequency band, the EEG is entrained to natural aperiodic music, and the response to the music is stronger to unfamiliar music than to familiar music. |
