The perception of musical phrase boundaries is a critical aspect of human musical experience: It allows us to organize, understand, derive pleasure from, and remember music. Identifying boundaries is a prerequisite for segmenting music into meaningful chunks, facilitating efficient processing and storage while providing an enjoyable, fulfilling listening experience through the anticipation of upcoming musical events. Expanding on Sridharan et al.'s [ , 521-532 (2007)] work on coarse musical boundaries between symphonic movements, we examined finer-grained boundaries. We measured the fMRI responses of 18 musicians and 18 nonmusicians during music listening. Using general linear model, independent component analysis, and Granger causality, we observed heightened auditory integration in anticipation to musical boundaries, and an extensive decrease within the fronto-temporal-parietal network during and immediately following boundaries. Notably, responses were modulated by musicianship. Findings uncover the intricate interplay between musical structure, expertise, and cognitive processing, advancing our knowledge of how the brain makes sense of music.
它使我们能够组织、理解、从中获得乐趣并记住音乐。识别边界是将音乐分割成有意义的片段的前提，通过预期即将发生的音乐事件，促进高效的处理和存储，同时提供令人愉悦、充实的聆听体验。在 Sridharan 等人关于交响乐乐章之间的粗粒度音乐边界的工作基础上，我们研究了更细粒度的边界。我们在音乐聆听过程中测量了 18 名音乐家和 18 名非音乐家的 fMRI 反应。使用广义线性模型、独立成分分析和格兰杰因果关系，我们观察到在音乐边界之前的听觉整合增强，并且在边界期间和之后立即在额颞顶叶网络中广泛减少。值得注意的是，反应受到音乐专业知识的调节。研究结果揭示了音乐结构、专业知识和认知处理之间的复杂相互作用，增进了我们对大脑如何理解音乐的理解。
