Research works for the effects of acupuncture on cortical evoked potentials were reviewed since 1970 in this article. As a result of the acupuncture anesthesia being applied widely in clinical operation, most of the studies were focused on the evoked potential of somatosensory cortex for elucidating the principle of the analgesic effect of acupuncture, while less observations were reported on the aspects of auditory and visual cortex. The amplitude of the evoked potential was often used as an index in assessing the excitability of the cerebral cortex in the studies of the effect of acupuncture in the past. An increase in the amplitude of evoked potential means an excitory process of the cortex and a decrease means depression. Based on their work, the authors consider that whether the change in the amplitude of cortical evoked potential could be served as an optional index in reflecting the excitability of the cortex is still a problem in neurophysiology remained for further investigation.
本文回顾了自1970年以来关于针刺对皮质诱发电位影响的研究工作。由于针刺麻醉在临床手术中广泛应用，大多数研究集中于躯体感觉皮质的诱发电位，以阐明针刺镇痛效应的原理，而关于听觉和视觉皮质方面的观察报道较少。在过去针刺效应的研究中，诱发电位的波幅常被用作评估大脑皮质兴奋性的指标。诱发电位波幅增加意味着皮质的兴奋过程，而波幅降低则意味着抑制。基于他们的工作，作者认为皮质诱发电位波幅的变化是否可作为反映皮质兴奋性的一个合适指标，仍是神经生理学中有待进一步研究的问题。
