在三碘季胺酚制动下，对５３只家兔进行实验。共引导海马单位放电２４６个，其中仅对伤害性刺激有反应的７３个，包括痛兴奋单位５３个（占２１．６％），痛抑制单位２０个（占８．１３％）。当刺激体感Ⅰ区或腓神经时，痛兴奋单位放电增加，时程延长，如果两项刺激同时作用，痛放电较任一单项刺激放电增加更明显，具协同兴奋的效应。电针两侧“内关”透“外关”后，重复上述实验，使痛兴奋单位放电减少，具有明显针效的７个，有效率达８７．５％，痛抑制单位放电抑制的现象减弱或解除抑制，观察４个单位均呈明显针效，有效率达１００％。注射杜冷丁后，对痛兴奋单位的影响与针效类似。提示：体感Ⅰ区参与了海马痛觉及电针镇痛的调节过程。
Fifty-three rabbits were tested under the action of triiodide quaternary ammonium phenol. A total of 246 electrical discharges were induced in the hippocampus, of which 73 were responsive to noxious stimuli alone, including 53 (21.6%) pain excitement units and 20 (8.73%) pain suppressive units. When stimulated somatosensory Ⅰ area or the peroneal nerve, pain excitement unit discharge increased duration prolongation, if the two stimuli simultaneously, pain discharge more than any single stimulus discharge more obvious increase, with synergistic excitement effect. Electroacupuncture on both sides of the “internal customs” through “foreign relations”, repeat the above experiment, the pain excitement units to reduce discharge, with obvious acupuncture effect 7, the effective rate of 87.5%, pain inhibition unit discharge inhibition decreased Or relieve the inhibition, the observation of 4 units showed obvious acupuncture, the effective rate of 100%. After injection of pethidine, the impact of pain and excitement units and needle effect similar. Tip: somatosensory I involvement in the regulation of hippocampal pain and electroacupuncture analgesia.
