论文摘要
音乐聆听涉及许多同时的神经操作，包括听觉处理，工作记忆，时间测序，音调跟踪，预期，回报和情感，因此，对音乐认知的全面研究将受益于全脑分析。在这里，我们使用两个基于复杂系统理论的网络措施来聆听各种音乐和语音听觉片段的过程：模块化，该措施衡量了大脑区域在社区中相互作用的程度以及灵活性，这些程度衡量了大脑区域将社区切换到其所属的社区的速度。在一项音乐和大脑连通性研究中，这是对音乐听力和中风恢复进行更大的临床研究的一部分，fMRI是在健康参与者中进行的，同时他们听取了自我选择的音乐，他们感受到了积极的情感依恋，以及文化上熟悉的音乐（J.S. Bach），文化上陌生的音乐（Gagakau court of Medief Music）（Gagakau court of Medieeem Japan）和几个演讲。在不同类型的听觉作品中，整个脑网络之间存在明显的对比，尤其是对于陌生的音乐而言。在自选和BACH的轨道上，参与者的全脑网络展示了模块化组织，该组织与网络灵活性非常协调。同时，当播放Gagaku音乐时，大脑网络模块化与灵活性之间的这种关系在很大程度上消失了。此外，虽然听觉皮层在自我选择的作品中的灵活性相当于巴赫期间的柔韧性，但在gagaku期间，它更加灵活。结果表明，全脑活动的模块化和灵活性度量有可能导致对现实世界歌曲音乐感知期间发生的复杂神经功能的新见解。
Music listening involves many simultaneous neural operations, including auditory processing, working memory, temporal sequencing, pitch tracking, anticipation, reward, and emotion, and thus, a full investigation of music cognition would benefit from whole-brain analyses. Here, we quantify whole-brain activity while participants listen to a variety of music and speech auditory pieces using two network measures that are grounded in complex systems theory: modularity, which measures the degree to which brain regions are interacting in communities, and flexibility, which measures the rate that brain regions switch the communities to which they belong. In a music and brain connectivity study that is part of a larger clinical investigation into music listening and stroke recovery, fMRI was performed on healthy participants while they listened to self-selected music to which they felt a positive emotional attachment, as well as culturally familiar music (J.S. Bach), culturally unfamiliar music (Gagaku court music of medieval Japan), and several excerpts of speech. There was a marked contrast among the whole-brain networks during the different types of auditory pieces, in particular for the unfamiliar music. During the self-selected and Bach tracks, participants' whole-brain networks exhibited modular organization that was significantly coordinated with the network flexibility. Meanwhile, when the Gagaku music was played, this relationship between brain network modularity and flexibility largely disappeared. In addition, while the auditory cortex's flexibility during the self-selected piece was equivalent to that during Bach, it was more flexible during Gagaku. The results suggest that the modularity and flexibility measures of whole-brain activity have the potential to lead to new insights into the complex neural function that occurs during music perception of real-world songs.
