摘　　要：对36例自愿受试者给予痛刺激穴位和非穴位,同时记录脊髓和皮层体感诱发电位,观察到痛刺激内关,合谷穴以及附近的非穴位点,记录到的脊髓诱发电位由 P-N-P 波组成,皮层诱发电位通常由 P_1、N_1、P_2、N_2、P_3、N_3P_4和 N_4等波组成复合波。该复合波的早成分由 P1、N1、P2组成,晚成分由 N2、P2、N3、P4和 N4等波组成,以上各波均有一定的潜伏期和振幅,痛刺激内关、合谷所记录的晚成分各波潜伏期均显著短于痛刺激内关、合谷附近的非穴位所记录的晚成分各波的潜伏期,而痛刺激穴位时,晚成分各波的振幅则显著大于刺激非穴位各波的振幅。这表明,痛刺激穴位所记录的传入信息是一种特征性的传入信息。对痛刺激穴位和非穴位所记录的颈脊髓诱发电位、皮层诱发电位各成分的分析,提示皮层可能是痛刺激穴位传入信息进行复杂整合过程的重要部位。The experiments were carried out on 36 normal subjects.Pain stimulation points are atNeiguan or Hegu and pain stumulation nonpoints are nearby Neiguan or Hegu.The Record loca-tions are at vertex and cervical vertebrae.The feature of evoked cerbrebral potential(ECP)and spinal cord ovoked potential(ESP)bypain stimulation the points or non-points were studied.The results have been obtained.1.Pain stimulation point ECP generally consists of wave P1、N1、P2、N2、P3、N3、P4 and N4.There is a certain amplitude and latency of each wave.2.The elements of pain stimulation non-point ECP are Similar to point ECP in the feature.Camparing Pain stimulation Point ECP with non-point ECP,the amplitude of wave P3-N3 ofstimulation point ECP increases(P<0.05)3.Pain stimulation Point ESP and non-point ESP consist of wave P1、N1 and P2、N3.Cam-paring Pain stmulation point with non-point there are no.significant changes in the amplitude andthe latency of ESP.
