Modulation der Gehirnaktivitäten bei gesunden Individuen durch Akupunktur am Dickdarm 11
Abstract
This study investigated the effect of acupuncture at Quchi (LI11) on brain activities in healthy individuals. Sub-band power and EEG microstate analyses were conducted during pre-acupuncture, acupuncture, needle-retention, and post-acupuncture phases in both the acupuncture group (n = 16) and the control group (n = 18). Four microstate classes (A–D) were identified. Regression analyses and two-factor ANOVAs with Bonferroni correction were performed. The acupuncture group exhibited a significant reduction in beta power during the acupuncture phase. Further analysis revealed that acupuncture at LI11 mainly affected delta, theta, and alpha band power in specific brain regions: delta power increased predominantly in the parietal, occipital, and central lobes, while theta and alpha power decreased mainly in the temporal, frontal, parietal, and occipital lobes. During the acupuncture phase, participants in the acupuncture group demonstrated a significant increase in both the duration and contribution of microstate A, as well as bidirectional transition probabilities between A and B/D. These findings suggest that acupuncture at LI11 significantly enhances microstate A activity and may strengthen functional connectivity between the auditory network and either the visual network or the dorsal attention network. Overall, acupuncture at LI11 predominantly modulates activities in the frontal, temporal, parietal, and occipital lobes. These findings underscore the potential of microstate analysis as neuroimaging-based evidence and a specific index for elucidating the neuromodulatory effects of acupuncture at LI11.
