Acupuncture, a traditional Chinese therapy, is gaining attention for its impact on the brain. While existing electroencephalogram and functional magnetic resonance image research has made significant contributions, this paper utilizes stereo-electroencephalography data for a comprehensive exploration of neurophysiological effects. Employing a multi-scale approach, channel-level analysis reveals notable $\delta $-band activity changes during acupuncture. At the brain region level, acupuncture modulated connectivity between the paracentral lobule and the precentral gyrus. Whole-brain analysis indicates acupuncture’s influence on network organization, and enhancing $E_{glob}$ and increased interaction between the motor and sensory cortex. Brain functional reorganization is an important basis for functional recovery or compensation after central nervous system injury. The use of acupuncture to stimulate peripheral nerve trunks, muscle motor points, acupoints, etc., in clinical practice may contribute to the reorganization of brain function. This multi-scale perspective provides diverse insights into acupuncture’s effects. Remarkably, this paper pioneers the introduction of stereo-electroencephalography data, advancing our understanding of acupuncture’s mechanisms and potential therapeutic benefits in clinical settings.

基于SEEG数据的针刺运动和感觉皮层活动机制的多尺度分析

针灸是一种传统的中医疗法，因其对大脑的影响而受到关注。虽然现有的脑电图和功能磁共振图像研究已经做出了重大贡献，但本文利用立体脑电图数据来全面探索神经生理效应。采用多尺度方法，通道级分析揭示了针灸过程中显着的$\delta$带活动变化。在大脑区域水平，针灸调节旁中央小叶和中央前回之间的连接。全脑分析表明针灸对网络组织的影响，增强 $E_{glob}$ 并增加运动皮层和感觉皮层之间的相互作用。脑功能重组是中枢神经系统损伤后功能恢复或代偿的重要基础。在临床上利用针灸刺激周围神经干、肌肉运动点、穴位等，可能有助于大脑功能的重组。这种多尺度的视角提供了对针灸效果的不同见解。值得注意的是，本文开创了立体脑电图数据的引入，增进了我们对针灸机制和临床环境中潜在治疗益处的理解。
