| 摘 要： | <正> 近年来研究证明脑内存在有以脑室周围灰质和导水管周围灰质为中心的镇痛系统。它可以通过延髓的下行抑制通路,阻遏脊髓背角痛信息的输入而起到镇痛作用。我们以往的工作多次证明电针“足三里”确实可以激活延脑中缝大核(NRM)这

COMPARAISON OF EFFECTS OF EA AT "HEGU" ON NOCICEPTIVE RESPONSES OF NRM NEURONS TO NOXIOUS STIMULATION OF THE FACE AND TAIL |
| |
| Abstract: | The experiments were performed on the rats. Unit discharges in NRM and their nociceptive responses to dental pulp and tail noxious stimulations were recorded extracellularly with glass microelectrodes. We observed that EA at the "Hegu" acupoint could increase spontaneous discharges of NRM neurons and inhibit their nociceptive responses to noxious stimulation acting on dental pulp and tail. It is interestingly noted that the inhibitory effect of EA on noxious stimulation applying on the pulp is stronger than the tail. |
