Music is a universal and important human trait, which is orchestrated by complex brain network centered in the temporal lobe but connecting broadly to multiple cortical and subcortical regions. In the human brain, music engages a widespread bilateral network of regions that govern auditory perception, syntactic and semantic processing, attention and memory, emotion and reward, and motor skills. The ability to perceive or produce music can be severely impaired either due to abnormal brain development or brain damage, leading to a condition called amusia. Modern neuroimaging studies of amusia have provided valuable knowledge about the structure and function of specific brain regions and white matter pathways that are crucial for music perception, highlighting the role of the right frontotemporal network in this process. In this chapter, we provide an overview on the neural basis of music processing in a healthy brain and review evidence obtained from the studies of congenital and acquired amusia.
音乐是一种普遍而重要的人类特质，由以颞叶为中心的复杂大脑网络协调，但广泛连接到多个皮质和皮质下区域。在人类大脑中，音乐涉及到一个广泛的双侧区域网络，这些区域负责听觉感知、句法和语义处理、注意力和记忆、情感和奖励以及运动技能。由于大脑发育异常或脑损伤，感知或产生音乐的能力可能会严重受损，导致一种称为失歌症的疾病。失歌症的现代神经影像学研究提供了关于特定大脑区域和白质通路结构和功能的宝贵知识，这些区域和白质通路对音乐感知至关重要，突出了右额颞网络在这个过程中的作用。在本章中，我们提供了一个关于健康大脑中音乐处理的神经基础的概述，并回顾了从先天性和获得性失歌症研究中获得的证据。
