摘要 目的 :观察穴位电刺激对豚鼠听皮质中潜伏期诱发电位波幅的影响。方法 :分别以电针和重复电脉冲刺激豚鼠前肢的外关、中渚穴 ,刺激前后记录短声诱发的听皮质中潜伏期诱发电位 ,并分析两种电刺激方式对诱发电位波幅的不同影响。结果 :电针前肢穴时 ,电针期间诱发电位波幅明显减小 ,而重复电脉冲刺激前肢穴时 ,波幅明显增大。结论 Objective:To study the effect of electro stimulation of points on amplitudes of auditory middle latency response in guinea pigs.Method:Electro acupuncture stimulation(unsynchronous with the click) and repetitive electrical stimulation(synchronized with the click) of points on foreleg(Waiguan and Zhongzhu)were administered to guinea pigs of two groups respectively.Auditory middle latency responses evoked by click were recorded before and after the stimulation,and the different effects of these two electro stimulation modalities on the amplitudes of the evoked response were analyzed.Result:The amplitudes of the evoked response decreased greatly during the electro acupuncture period when electro acupuncture of points on foreleg was administered,while the amplitudes increased greatly with the administration of repetitive electrical stimulation.Conclusion:It is not proper to assess the excitability of the cerebral cortex only by the changes of the amplitudes of the evoked potential during electro acupuncture.
