针灸刺激增加刺激部位周围的局部血流，并诱导与身体基质相关的大脑区域的信号变化。橡胶手错觉（RHI）是一种操纵身体自我意识重要方面的实验范式。本研究的目的是探讨如何修改身体所有权使用RHI影响局部血流和脑反应在针灸针刺激。在RHI期间，将针灸针刺激施加到真实的左手，同时用激光多普勒成像仪（实验1，N = 28）测量血液微循环，并使用功能性磁共振成像（fMRI;实验2，N = 17）测量脑信号变化。 当参与者的身体所有权被RHI改变时，针刺刺激导致局部血流量的增加显著降低（实验1），并且在右侧丘脑中检测到显著减少的脑激活（实验2）。这项研究发现，在身体所有权改变后，针灸针刺激期间局部血流和大脑反应都会发生变化。这些发现表明，在针灸刺激的生理反应可以通过修改身体所有权的影响。
Acupuncture stimulation increases local blood flow around the site of stimulation and induces signal changes in brain regions related to the body matrix. The rubber hand illusion (RHI) is an experimental paradigm that manipulates important aspects of bodily self-awareness. The present study aimed to investigate how modifications of body ownership using the RHI affect local blood flow and cerebral responses during acupuncture needle stimulation. During the RHI, acupuncture needle stimulation was applied to the real left hand while measuring blood microcirculation with a LASER Doppler imager (Experiment 1, N = 28) and concurrent brain signal changes using functional magnetic resonance imaging (fMRI; Experiment 2, N = 17). When the body ownership of participants was altered by the RHI, acupuncture stimulation resulted in a significantly lower increase in local blood flow (Experiment 1), and significantly less brain activation was detected in the right insula (Experiment 2). This study found changes in both local blood flow and brain responses during acupuncture needle stimulation following modification of body ownership. These findings suggest that physiological responses during acupuncture stimulation can be influenced by the modification of body ownership.
