Abstract

Neural oscillations in beta (13-30 Hz) and gamma (>30 Hz) frequency bands index a variety of sensorimotor and cognitive processes. To compare two rehabilitation regimens for chronic stroke patients with a hemiparetic hand, we randomly assigned them to either music-supported therapy or physiotherapy for 10 weeks. Previously, we reported the music group's improved motor speed, mood, well-being, and rhythm perception. Here, we investigated changes in neural oscillatory activities. Here, our magnetoencephalography (MEG) data showed significant group-by-session interaction in both somatosensory and auditory-motor paradigms. The control group exhibited a prominent increase in gamma-band frequencies accompanying the somatosensory steady-state responses entrained by 22-Hz vibrotactile stimulation, indicating compensatory functions from the contralesional brain. In contrast, the music group showed a gradual enhancement of auditory-motor coupling in beta-band event-related power changes during passive metronome listening. The music group's increase in beta dynamics in the auditory cortex aligns with our previous work and their improvement in behavioral rhythm perception. Whole-brain data during listening and tapping demonstrated reduced beta modulation in the sensorimotor and prefrontal cortices and temporal poles in the music group, likely related to movements with less effort and attention. The current findings contribute to understanding the frequency-specific communications of the auditory, sensory, and motor systems.

使用音乐支持疗法和手工训练的慢性中风康复中的β和γ波段神经磁振荡。

β (13- 30hz)和γ (bb0 - 30hz)频段的神经振荡反映了各种感觉运动和认知过程。为了比较两种治疗手部偏瘫的慢性中风患者的康复方案，我们将他们随机分配到音乐支持疗法或物理疗法中，为期10周。之前，我们报道了音乐组的运动速度、情绪、幸福感和节奏感的改善。在这里，我们研究了神经振荡活动的变化。在这里，我们的脑磁图（MEG）数据显示了躯体感觉和听觉-运动范式中显著的组-会话交互作用。对照组在22赫兹振动触觉刺激下，伴随体感稳态反应的伽马波段频率显著增加，表明对侧脑的代偿功能。相比之下，在被动听节拍器时，音乐组在β频带事件相关的功率变化中表现出听觉-运动耦合的逐渐增强。音乐组听觉皮层中β动态的增加与我们之前的研究结果一致，他们在行为节奏感知方面的改善。听音乐和敲击时的全脑数据显示，音乐组的感觉运动皮层、前额叶皮层和颞极的β调制减少，这可能与较少努力和注意力的运动有关。目前的研究结果有助于理解听觉、感觉和运动系统的频率特异性交流。

期刊介绍： Published on behalf of the New York Academy of Sciences, Annals of the New York Academy of Sciences provides multidisciplinary perspectives on research of current scientific interest with far-reaching implications for the wider scientific community and society at large. Each special issue assembles the best thinking of key contributors to a field of investigation at a time when emerging developments offer the promise of new insight. Individually themed, Annals special issues stimulate new ways to think about science by providing a neutral forum for discourse—within and across many institutions and fields.
