摘要 本文对七十年代以来有关针刺对大脑皮层诱发电位影响的研究进行了全面的综述。在研究针刺镇痛原理时,常常以体感诱发电位作为反映疼痛的客观指标,故有关针刺对大脑皮层诱发电位影响的研究大多为体感诱发电位的研究。针刺对视觉和听觉诱发电位影响的研究较少。在以往的诱发电位研究中常以波幅大小来代表皮层的兴奋性,诱发电位的波幅减小是否代表皮层处于抑制状态而波幅加大是否代表兴奋仍值得探讨。故仍有必要深入开展针刺过程中大脑皮层兴奋性变化的研究。 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 priciple 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
