Abstract
Background Hegu is the most commonly used acupoints for pain relief. Recently, several functional neuroimaging studies have been performed on acupuncture at Hegu in healthy volunteers, but these studies have yielded diverse findings. Therefore, there is an urgent need to understand the brain response characteristics of acupuncture at Hegu. Methods Neuroimaging studies on acupuncture at Hegu published before October 2022 were collected from PubMed, Web of Science, Google Scholar, Embase, and CNKI (China National Knowledge Infrastructure) databases, and were screened by strict inclusion and exclusion criteria. The extraction of brain coordinates was performed by two independent researchers, and the results were analyzed using activation likelihood estimation (ALE) analysis based on quantitative coordinates. Results In total, 338 studies were searched, of which 19 studies were included in the final analysis after a rigorous double-blind screening review. Activation likelihood estimation showed that postcentral gyrus in the left brain were activated, whereas the anterior cingulate in the left brain and superior temporal gyrus in the right brain were deactivated. Conclusion Acupuncture at Hegu in healthy volunteers did not reveal specific brain regions. This finding implies that organismal status of the study subjects may have an important impact on the effect of acupoints.

Abstract
Objective Recent functional MRI (fMRI) studies show that brain activity, including the default mode network (DMN), can be modulated by acupuncture. Conventional means to enhance the neurophysiological ‘dose’ of acupuncture, including an increased number of needles and manual needle manipulation, are expected to enhance its physiological effects. The aim of this study was to compare the effects of both methods on brain activity. Methods 58 healthy volunteers were randomly assigned into four groups that received single needle acupuncture (SNA, n=15) or transcutaneous electrical nerve stimulation (TENS, n=13) as active controls, or enhanced acupuncture by way of three needle acupuncture (TNA, n=17) or SNA plus manual stimulation (SNA+MS, n=13). Treatment-associated sensations were evaluated using a visual analogue scale. Central responses were recorded before, during, and after treatment at LI4 on the left hand using resting state fMRI. Results TNA and SNA+MS induced DMN-insula activity and extensive DMN activity compared to SNA, despite comparable levels of de qi sensation. The TNA and SNA+MS groups exhibited a delayed and enhanced modulation of the DMN, which was not observed followed SNA and TENS. Furthermore, TNA increased precuneus activity and increased the DMN-related activity of the cuneus and left insula, while SNA+MS increased activity in the right insula. Conclusions The results showed that conventional methods to enhance the acupuncture dose induce different DMN modulatory effects. TNA induces the most extensive DMN modulation, compared with other methods. Conventional methods of enhancing the acupuncture dose could potentially be applied as a means of modulating brain activity.

Abstract
OBJECTIVE To examine gender differences and similarities in the psychophysical and brain responses to acupuncture at GB34, a point that is frequently used to treat motor function issues in Traditional Chinese Medicine. METHODS Functional MRI (fMRI) was used to measure brain activation in response to acupuncture at GB34 (on the right) in 19 healthy participants (9 male, 10 female). De qi sensations were rated to measure their psychophysical responses. RESULTS Overall de qi scores did not differ by gender, although females reported greater intensity of aching (p=0.04). Acupuncture activated the hippocampus, thalamus, globus pallidus, caudate body, claustrum, cingulate gyrus, and culmen in males, and the middle and inferior frontal gyrus, precuneus, postcentral gyrus, inferior parietal lobule, superior temporal gyrus, caudate body, insula, fusiform gyrus, cingulate gyrus, amygdala, and parahippocampal gyrus in females. The middle/medial frontal gyrus, middle temporal gyrus, thalamus, globus pallidus, caudate body, uvula, and cerebellar tonsil were activated when data from all subjects were combined. Relative to males, females exhibited greater brain activation in the right-sided postcentral gyrus, precentral gyrus, precuneus, postcentral gyrus, inferior parietal lobule, declive, middle occipital gyrus and parahippocampal gyrus. CONCLUSIONS The neural effects of GB34 acupuncture might differ between males and females because different brain structures were modulated in response to acupuncture. This potential gender effect should be taken into account in future clinical research. We also revealed that the caudate body was activated by GB34 acupuncture in both males and females and may represent a major target of GB34 acupuncture. TRIAL REGISTRATION NUMBER KMC IRB 0861-06.
