尽管音乐具有明显的普遍性和很高的社会价值，但人们对音乐的最终生物学作用及其与大脑疾病的联系仍然知之甚少。基础神经科学的最新发现为这些老问题提供了新的线索。临床神经科学提供的关于大脑疾病影响的新见解有望在揭示音乐的潜在认知和神经结构以及评估音乐的生物学作用的候选帐户方面特别有价值。在这里，我们利用来自正常和紊乱大脑的比较行为学、认知神经心理学和神经影像学研究的多种证据，提出了音乐在人类进化中的生物学作用以及与大脑疾病的联系的新模型。我们认为，音乐是从我们原始人类祖先的呼叫信号演变而来的，作为一种心理手段，以替代、编码、低成本的形式排练和预测可能成本高昂、充满情感的社会惯例：本质上，是一种有效、适应性地将情绪心理状态转化为社会信号的机制。音乐的这种生物学作用如今在音乐和精神状态的无序处理中留下了遗产，这些无序的处理是大脑网络瓦解的某些发育性和后天性临床综合症的特征。
Despite its evident universality and high social value, the ultimate biological role of music and its connection to brain disorders remain poorly understood. Recent findings from basic neuroscience have shed fresh light on these old problems. New insights provided by clinical neuroscience concerning the effects of brain disorders promise to be particularly valuable in uncovering the underlying cognitive and neural architecture of music and for assessing candidate accounts of the biological role of music. Here we advance a new model of the biological role of music in human evolution and the link to brain disorders, drawing on diverse lines of evidence derived from comparative ethology, cognitive neuropsychology and neuroimaging studies in the normal and the disordered brain. We propose that music evolved from the call signals of our hominid ancestors as a means mentally to rehearse and predict potentially costly, affectively laden social routines in surrogate, coded, low-cost form: essentially, a mechanism for transforming emotional mental states efficiently and adaptively into social signals. This biological role of music has its legacy today in the disordered processing of music and mental states that characterizes certain developmental and acquired clinical syndromes of brain network disintegration.
