Abstract

Virtual reality (VR) has gained popularity in recent years, integrating with conventional music stimulation (MS), action observation (AO), and motor imagination (MI). It offers promising opportunities for developing innovative rehabilitation treatments, though the mechanisms underlying these effects remain unclear. This study aims to compare brain activation and network mechanisms following the fusion of MS, AO, and MI with VR. Fifty healthy participants were recruited and underwent functional near-infrared spectroscopy synchronization with three VR tasks: MS (VRMS), AO (VRAO), and MI (VRMI). The results indicate that VRMS significantly enhances functional connectivity of the bilateral primary sensory cortex (S1), premotor cortex, and supplementary motor area (PM&SMA) compared with VRAO and VRMI. Furthermore, the interaction among the bilateral PM&SMA, right dorsolateral prefrontal cortex, and right primary motor cortex (M1) regions is notably stronger with VRMS than with the other VR tasks. These findings elucidate the brain activation and network characteristics of the three VR tasks, highlighting VRMS's potential in boosting the functional interaction among brain regions. Future research should explore additional brain regions, broader diseased brain samples, and alternative brain-stimulation effects of VRMS.

虚拟现实技术中音乐刺激、运动观察和运动想象的脑机制:功能近红外光谱研究。
近年来,虚拟现实(VR)与传统的音乐刺激、动作观察(AO)和运动想象(MI)相结合,得到了广泛的应用。它为开发创新的康复治疗提供了有希望的机会,尽管这些影响的机制尚不清楚。本研究旨在比较MS、AO和MI与VR融合后的脑激活和网络机制。招募了50名健康的参与者,并在三个虚拟现实任务中进行了功能近红外光谱(fNIRS)同步:音乐刺激(VRMS)、动作观察(VRAO)和运动想象(VRMI)。结果表明,与VRAO和VRMI相比,VRMS显著增强了双侧初级感觉皮质(S1)、运动前皮质和辅助运动区(PM&SMA)的功能连接。此外,双侧PM&SMA、右侧背外侧前额叶皮层(DLPFC)和右侧初级运动皮层(M1)区域在VRMS任务中的相互作用明显强于其他VR任务。这些发现阐明了三种虚拟现实任务的大脑激活和网络特征,突出了VRMS在促进大脑区域之间功能相互作用方面的潜力。未来的研究应该探索更多的脑区,更广泛的病变脑样本,以及VRMS的其他脑刺激作用。作为已建立的非侵入性神经调节模式,音乐刺激(MS)、动作观察(AO)和运动想象(MI)面临两个临床限制:过于简单的任务设计降低了治疗的显著性,损害了患者的参与。虚拟现实(VR)集成通过增强沉浸式和多感官刺激解决了这些限制。本研究探讨了VRMS、VRAO和VRMI任务时的皮层激活动态和功能网络。功能近红外光谱(fNIRS)结果表明,与VRAO和VRMI任务相比,VRMS诱导了更好的功能连接调制,特别是在感觉运动整合中。这些发现有助于优化虚拟现实康复模式的选择,推进虚拟现实技术的探索。
