　　美國(guó)北卡羅萊納大學(xué)等處的研究人員表明，聽(tīng)一首自己喜歡的歌曲似乎會(huì)觸發(fā)一個(gè)共同的腦活動(dòng)模式，而不管這首歌曲的風(fēng)格是什么。這些發(fā)現(xiàn)也許可解釋為什么在聽(tīng)他們喜歡的音樂(lè)(不管是貝多芬的還是艾米納姆的)時(shí)，不同的人會(huì)有相似的情緒感覺(jué)和記憶反應(yīng)。相關(guān)文章發(fā)表于2014年8月28日的《Scientific Reports》雜志上。

　　音樂(lè)喜好在很大程度上是因人而異的，不同音樂(lè)類型在其旋律、和聲特征以及節(jié)奏復(fù)雜性上會(huì)有實(shí)質(zhì)性差別。然而，當(dāng)聽(tīng)自己喜歡的音樂(lè)時(shí)，人經(jīng)常會(huì)提到相同的反應(yīng)——勾起個(gè)人想法和記憶。

　　為了解為什么不同的人會(huì)有相似的體驗(yàn)，Jonathan Burdette及同事對(duì)21個(gè)人在聽(tīng)不同類型音樂(lè)、包括搖滾、說(shuō)唱和古典音樂(lè)時(shí)功能性腦網(wǎng)絡(luò)的差別進(jìn)行了評(píng)估(他們所采用的是“功能性磁共振成像”、即fMRI數(shù)據(jù))。他們識(shí)別出了與歌曲喜好相關(guān)的一致的腦連接模式。當(dāng)聽(tīng)他們自稱喜歡的歌曲時(shí)，該研究的參加者在一個(gè)與“心無(wú)旁騖”相關(guān)的腦回路中表現(xiàn)出連接增強(qiáng)，同時(shí)在聽(tīng)覺(jué)腦區(qū)域與負(fù)責(zé)記憶和社會(huì)化情緒之鞏固的區(qū)域之間的聯(lián)系顯示被改變。

Network Science and the Effects of Music Preference on Functional Brain Connectivity: From Beethoven to Eminem

R. W. Wilkins, D. A. Hodges, P. J. Laurienti, M. Steen & J. H. Burdette

　　Most people choose to listen to music that they prefer or ‘like’ such as classical, country or rock. Previous research has focused on how different characteristics of music (i.e., classical versus country) affect the brain. Yet, when listening to preferred music—regardless of the type—people report they often experience personal thoughts and memories. To date, understanding how this occurs in the brain has remained elusive. Using network science methods, we evaluated differences in functional brain connectivity when individuals listened to complete songs. We show that a circuit important for internally-focused thoughts, known as the default mode network, was most connected when listening to preferred music. We also show that listening to a favorite song alters the connectivity between auditory brain areas and the hippocampus, a region responsible for memory and social emotion consolidation. Given that musical preferences are uniquely individualized phenomena and that music can vary in acoustic complexity and the presence or absence of lyrics, the consistency of our results was unexpected. These findings may explain why comparable emotional and mental states can be experienced by people listening to music that differs as widely as Beethoven and Eminem. The neurobiological and neurorehabilitation implications of these results are discussed.
