我们研究了在有和没有刺激的情况下，大脑对穴位周围增强身体注意力的反应的共性和差异。14名参与者在左手的PC6和HT7穴位接受针灸针。为了提高身体对穴位的注意力，参与者在两个选择的强迫选择任务中对刺激的位置做出反应。两个功能磁共振成像扫描在一个区块设计：会话1标记与手动刺激（真正的刺激）和会话2标记与电针（伪刺激）。为了比较皮质激活模式，使用Freesurfer软件包分析数据。脑刺激和假刺激都导致大脑皮层、前扣带皮层、次级体感皮层、上级顶叶皮层的激活，以及内侧前额叶皮层、后扣带皮层、顶叶皮层和海马旁的失活。与假刺激相比，真实针刺刺激在后扣带回、后盖和前扣带皮质的尾部表现出更大的脑激活。我们证明，无论刺激类型如何，真正的针灸刺激触发的增强身体注意力都可以激活显着网络并停用默认模式网络。对身体某个部位的注意力增强的成分在针刺刺激的脑反应中是显著的。
We investigated commonalities and differences in brain responses to enhanced bodily attention around acupuncture points with and without stimulation. Fourteen participants received acupuncture needles at both PC6 and HT7 acupoints in the left hand. To enhance bodily attention to acupoints, participants responded to the locations of stimulations in a two-alternative forced choice task. Two fMRI scans were taken in a block design: session 1 labeled with manual stimulation (genuine stimulation) and session 2 labeled with electro-acupuncture (pseudo-stimulation). To compare cortical activation patterns, data were analyzed using the Freesurfer software package. Both genuine-and pseudo-stimulation resulted in brain activations in the insula, anterior cingulate cortex, secondary somatosensory cortex, superior parietal cortex, and brain deactivation in the medial prefrontal cortex, posterior cingulate cortex, inferior parietal cortex, and the parahippocampus. Genuine acupuncture stimulation exhibited greater brain activation in the posterior insula, posterior operculum and the caudal part of the anterior cingulate cortex, compared with pseudo-stimulation. We demonstrated that enhanced bodily attention triggered by genuine acupuncture stimulation can activate the salience network and deactivate the default mode network regardless of the type of stimulation. The component of enhanced attention to a certain part of the body is significant in the brain response to acupuncture stimulation.
