Acupuncture is an ancient East Asian healing modality that has been in use for more than 2000 years. Unfortunately, its mechanisms of action are not well understood, and controversy regarding its clinical efficacy remains. Importantly, acupuncture needling often evokes complex somatosensory sensations and may modulate the cognitive/affective perception of pain, suggesting that many effects are supported by the brain and extending central nervous system (CNS) networks. Modern neuroimaging techniques such as functional magnetic resonance imaging, positron emission tomography, electroencephalography, and magnetoencephalography provide a means to safely monitor brain activity in humans and may be used to help map the neurophysiological correlates of acupuncture. In this review, we will summarize data from acupuncture neuroimaging research and discuss how these findings contribute to current hypotheses of acupuncture action.
针灸是一种古老的东亚治疗方法，已沿用两千多年。遗憾的是，其作用机制尚未完全明了，关于其临床疗效的争议依然存在。重要的是，针刺常常会引发复杂的躯体感觉，并可能调节对疼痛的认知/情感感知，这表明许多效应是由大脑及延伸的中枢神经系统（CNS）网络所支持的。现代神经成像技术，如功能磁共振成像、正电子发射断层扫描、脑电图和脑磁图，提供了一种安全监测人体大脑活动的方法，可用于帮助描绘针灸的神经生理相关性。在这篇综述中，我们将总结针灸神经成像研究的数据，并讨论这些发现如何有助于当前对针灸作用的假设。
