摘要

本研究探讨了针刺曲池(LI11)对健康人大脑活动的调节作用。对针刺组(16 人)和对照组(18 人)进行了针刺前、针刺、留针和针刺后的子带功率和脑电图微状态分析。根据聚类程序得出四个微状态类别(A-D)。我们进行了回归分析和双向重复测量方差分析,然后进行了 Bonferroni 校正。在针刺组中,我们发现针刺期的β功率明显降低。逐通道分析显示,针刺LI11主要改变了特定脑区的δ波、θ波和α波的功率。δ波功率主要在顶叶、枕叶和中央叶增加,而θ波和α波功率主要在颞叶、额叶、顶叶和枕叶减少。在针灸期间,针灸组参与者的微状态 A 的持续时间和贡献率以及双向转换概率 A 和 B/D 都有显著增加。微态分析表明,针刺LI11能显著增强微态A的活动,并有可能加强听觉网络与视觉网络或背侧注意网络之间的功能连接。这些相关结果表明,针刺LI11主要影响额叶、颞叶、顶叶和枕叶的活动。这些发现凸显了微状态作为神经影像学证据的潜力,以及作为阐明针刺LI11神经调节效应的特定指标的潜力。

Modulation of Brain Activities in Healthy Individuals by Acupuncture at Quchi (LI11).

This research investigated the modulation of acupuncture at Quchi (LI11) on the brain activities in healthy individuals. Sub-bands power and EEG microstate analysis were carried out at pre-acupuncture, acupuncture, needle retaining and post-acupuncture periods in both the acupuncture group (n = 16) and control group (n = 18). Four microstate classes (A-D) were derived from the clustering procedure. Regression analysis was conducted, together with a two-way repeated measures ANOVA, which was then followed by Bonferroni correction. In the acupuncture group, we found the beta power during the acupuncture periods was significantly reduced. The channel-by-channel analysis revealed that acupuncture at LI11 mainly altered the power of delta, theta, and alpha waves in specific brain regions. The delta power increased predominantly in parietal, occipital, and central lobes, while theta and alpha power decreased predominantly in temporal, frontal, parietal, and occipital lobes. During the acupuncture period, participants in the acupuncture group showed a significant increase in both duration and contribution of microstate A, as well as the bidirectional transition probabilities A and B/D. Microstate analysis showed that acupuncture at LI11 significantly enhances the activity of microstate A and potentially strengthens the functional connectivity between the auditory network and either the visual network or the dorsal attention network. These correlational results indicate that acupuncture at LI11 mainly affects activities of the frontal, temporal, parietal, and occipital lobes. These findings highlight the potential of microstate as neuroimaging evidence and a specific index for elucidating the neuromodulatory effects of acupuncture at LI11.
