我们以往的工作观察到,猫的皮层SⅡ区参与对丘脑髓板内核群Pf、CM和CL神经元伤害性反应和针刺镇痛效应的下行性调节。本文观察在皮层SⅠ区施加GABA或利多卡因对猫的Pf或CM神经元针刺镇痛效应的影响,以探讨SI区是否也参与对丘脑髓板内核群针刺镇痛
Our previous work has observed that the cat’s cortex S II region is involved in the descending regulation of the nociceptive responses to the neurons of Pf, CM and CL neurons and the acupuncture analgesic effects in the medullary platelet nucleus. In this study, we observed the effect of GABA or lidocaine on the analgesic effects of acupuncture on cats Pf or CM neurons in the cortex S Ⅰ area to explore whether SI region is also involved in acupuncture analgesia
