论文摘要
我们分析了在健康人类受试者中测得的经验结构连通性的Fitzhugh-Nagumo振荡器网络中音乐的影响。我们报告网络中的全球动态与特定音乐歌曲引起的输入信号之间的相干性提高。我们表明，相干性水平在频带上至关重要。我们将结果与实验数据进行了比较，这些结果还描述了伽马范围内不同大脑区域之间的全球神经同步及其在音乐形式不同部分之间的过渡之前（音乐高级事件）之间的增加。结果还表明，与新皮层活动相关的高脑频率之间与音乐形式相关的大脑同步和舞蹈运动范围的低频，与皮质和皮层区域之间的相互作用有关。
We analyze the influence of music in a network of FitzHugh-Nagumo oscillators with empirical structural connectivity measured in healthy human subjects. We report an increase of coherence between the global dynamics in our network and the input signal induced by a specific music song. We show that the level of coherence depends crucially on the frequency band. We compare our results with experimental data, which also describe global neural synchronization between different brain regions in the gamma-band range and its increase just before transitions between different parts of the musical form (musical high-level events). The results also suggest a separation in musical form-related brain synchronization between high brain frequencies, associated with neocortical activity, and low frequencies in the range of dance movements, associated with interactivity between cortical and subcortical regions.
