查询词典 tract

The activation of NRM neurons by electroaeupuncture was eliminated after decerebration at superior colliculus level, indicating that this effect of EA depends mainly on the supra-midbrain structure. Furthermore, all treatments including AR isolation, disconnection of #beta#-endorphinergic tract and micrpinjection of naloxone or anti-#beta#-endorphin serum into PAG, would make the effect of EA disappear. Thus, it is the #beta#-endorphinergic pathway between AR and PAG-NRM system that mediates the major excitatory effect of EA on NRM.

检验AR至 PAG-NRM的神经通路在电针效应中的作用：实验显示上丘水平去大脑后，电针兴奋NRM的效应完全消失，表明此效应主要依赖中脑以上结构实现，进一步分别用Halfisz氏刀游离AR、切断AR至PAG的β-End能束、PAG内注射纳洛酮或抗β-End血清后，也使电针效应基本上完全消失，说明电针使NRM神经元兴奋的效应，主要通过AR与PAG-NRM间的β-End能神经通路实现。
