In this chapter, we explore what happens in the brain of an expert musician during performance. Understanding expert music performance is interesting to cognitive neuroscientists not only because it tests the limits of human memory and movement, but also because studying expert musicianship can help us understand skilled human behavior in general. In this chapter, we outline important facets of our current understanding of the cognitive and neural basis for music performance, and developmental factors that may underlie musical ability. We address three main questions. (1) What is expert performance? (2) How do musicians achieve expert-level performance? (3) How does expert performance come about? We address the first question by describing musicians' ability to remember, plan, execute, and monitor their performances in order to perform music accurately and expressively. We address the second question by reviewing evidence for possible cognitive and neural mechanisms that may underlie or contribute to expert music performance, including the integration of sound and movement, feedforward and feedback motor control processes, expectancy, and imagery. We further discuss how neural circuits in auditory, motor, parietal, subcortical, and frontal cortex all contribute to different facets of musical expertise. Finally, we address the third question by reviewing evidence for the heritability of musical expertise and for how expertise develops through training and practice. We end by discussing outlooks for future work.
在本章中,我们探讨专业音乐家在演奏过程中大脑里发生了什么。认知神经科学家对理解专业音乐演奏感兴趣,不仅是因为它测试了人类记忆和运动的极限,还因为研究专业音乐才能总体上有助于我们理解人类的熟练行为。在本章中,我们概述了当前对音乐演奏的认知和神经基础以及可能构成音乐能力基础的发展因素的重要方面。我们探讨三个主要问题。(1)什么是专业演奏?(2)音乐家如何实现专业水平的演奏?(3)专业演奏是如何形成的?我们通过描述音乐家为了准确且富有表现力地演奏音乐而具备的记忆、计划、执行和监控其演奏的能力来探讨第一个问题。我们通过回顾可能构成专业音乐演奏基础或对其有贡献的认知和神经机制的证据来探讨第二个问题,这些机制包括声音与动作的整合、前馈和反馈运动控制过程、期待以及意象。我们进一步讨论听觉、运动、顶叶、皮层下和额叶皮质中的神经回路如何都对音乐专业技能的不同方面做出贡献。最后,我们通过回顾音乐专业技能遗传性的证据以及专业技能如何通过训练和练习发展的证据来探讨第三个问题。我们最后讨论未来工作的展望。
