加拿大一項(xiàng)最新研究顯示,，大腦在聽(tīng)音樂(lè)時(shí)的感覺(jué)可以比享受美食更好,，這正應(yīng)了孔子當(dāng)年聽(tīng)過(guò)美妙韶樂(lè)后的一句夸張感嘆,，“三月不知肉味”,。
新一期英國(guó)《自然·神經(jīng)科學(xué)》雜志刊登報(bào)告說(shuō),，加拿大麥基爾大學(xué)等機(jī)構(gòu)研究人員請(qǐng)一些對(duì)音樂(lè)“特別有感覺(jué)”的人參與試驗(yàn),，讓他們聽(tīng)各種不同的音樂(lè),，同時(shí)利用功能磁共振成像技術(shù)監(jiān)測(cè)其大腦活動(dòng)。結(jié)果顯示,，他們?cè)诼?tīng)特別喜歡的音樂(lè)時(shí),，大腦中的多巴胺含量明顯上升，這與美食在大腦中引起愉悅反應(yīng)時(shí)的情況相同,。
研究人員瓦洛里·薩里波爾說(shuō),，一般受試者在聽(tīng)喜歡的音樂(lè)時(shí)大腦中多巴胺含量上升幅度在6％到9％之間，不過(guò)也有人出現(xiàn)過(guò)21％的上升幅度,。以前的相關(guān)研究顯示,，美食一般也就使多巴胺含量上升6％。由此可見(jiàn),，在聽(tīng)過(guò)美妙的音樂(lè)后,，“三月不知肉味”也不是不可能,。
這項(xiàng)研究證實(shí)了音樂(lè)刺激也能引起與食物等實(shí)體刺激相同的反應(yīng)。不過(guò),，由于研究對(duì)象是從200多名自認(rèn)為對(duì)音樂(lè)“有感覺(jué)”的人中精心挑選出來(lái)的,，上述研究結(jié)論還不能簡(jiǎn)單地推廣到所有人中。（生物谷Bioon.com）

Anatomically distinct dopamine release during anticipation and experience of peak emotion to music
Valorie N Salimpoor,Mitchel Benovoy,Kevin Larcher,Alain Dagher& Robert J Zatorre
Music, an abstract stimulus, can arouse feelings of euphoria and craving, similar to tangible rewards that involve the striatal dopaminergic system. Using the neurochemical specificity of [11C]raclopride positron emission tomography scanning, combined with psychophysiological measures of autonomic nervous system activity, we found endogenous dopamine release in the striatum at peak emotional arousal during music listening. To examine the time course of dopamine release, we used functional magnetic resonance imaging with the same stimuli and listeners, and found a functional dissociation: the caudate was more involved during the anticipation and the nucleus accumbens was more involved during the experience of peak emotional responses to music. These results indicate that intense pleasure in response to music can lead to dopamine release in the striatal system. Notably, the anticipation of an abstract reward can result in dopamine release in an anatomical pathway distinct from that associated with the peak pleasure itself. Our results help to explain why music is of such high value across all human societies.
