The experiments were carried out on 36 normal subjects. Pain stimulation points are at Neiguan or Hegu and pain stimulation nonpoints are nearby Neiguan or Hegu. The Record locations are at cortex and cervical vertebrae. The feature of evoked cerebral potential (ECP) and spinal cord evoked potential (ESP) by pain 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. Comparing Pain stimulation Point ECP with non-point ECP, the amplitude of wave P3-N3 of stimulation point ECP increases (P < 0.05). 3. Pain stimulation Point ESP and non-point ESP consist of wave P1, N1 and P2, N3. Comparing Pain stimulation point with non-point there are no significant changes in the amplitude and the latency of ESP.
实验在36名正常受试者身上进行。疼痛刺激点位于内关或合谷，疼痛非刺激点位于内关或合谷附近。记录部位在皮层和颈椎。研究了疼痛刺激穴位或非穴位所诱发的脑诱发电位（ECP）和脊髓诱发电位（ESP）的特征。已获得结果。1. 疼痛刺激穴位的ECP一般由P1、N1、P2、N2、P3、N3、P4和N4波组成。各波有一定的波幅和潜伏期。2. 疼痛刺激非穴位的ECP成分在特征上与穴位ECP相似。比较疼痛刺激穴位的ECP与非穴位的ECP，刺激穴位的ECP中P3 - N3波的波幅增加（P < 0.05）。3. 疼痛刺激穴位的ESP和非穴位的ESP由P1、N1和P2、N3波组成。比较疼痛刺激穴位与非穴位，ESP的波幅和潜伏期无显著变化。
