本文考虑与音乐分析相关的复杂声音的时间处理。使用正电子发射断层扫描 (PET)、功能磁共振成像 (fMRI) 和脑磁图 (MEG) 的功能成像研究，以及对病变患者的心理物理学评估，可以采用两种不同的方法来实现这一目标。功能成像可以确定通常参与时间分析的结构，而患者研究可以推断时间分析所需的结构。这两种方法都表明大脑中存在与音乐处理相对应的层次结构。各个音符的特征在直至并包括听觉皮层的路径中进行分析，而由这些特征形成的高阶模式则通过与听觉皮层不同的颞叶和额叶中的分布式网络进行分析。
This paper considers the temporal processing of complex sounds relevant to musical analysis. Functional imaging studies, using positron emission tomography (PET), functional magnetic resonance imaging (fMRI), and magnetoencephalography (MEG), and the psychophysical assessment of patients with lesions allow two different approaches to this. Functional imaging allows the determination of structures normally involved in temporal analysis, while patient studies allow inference about the necessary structures for temporal analysis. Both approaches suggest a hierarchal organization in the brain corresponding to the processing of music. The features of individual notes are analyzed in the pathway up to and including the auditory cortices, while higher-order patterns formed by those features are analyzed by distributed networks in the temporal lobe and frontal lobes distinct from the auditory cortices.
