实验在75只25％Urethane麻醉、三碘季胺酚制动、断双侧颈迷走神经和人工通气的家兔上进行。探讨了兔孤束核腹外侧区微量注射神经无胞体抑制剂谷氨酸钠及甘氨酸,所引起的呼吸神经元兴奋活动变化对下丘脑弓状核诱发电位的影响并初步探讨了其可能的机制和意义。主要的实验结果如下:
Experiments were performed on 75 rabbits with 25% Urethane anesthesia, triiodide quaternary ammonium phenol block, bilateral vagus vagus nerve and artificial ventilation. To investigate the effect of the changes of excitatory activity of respiratory neurons on evoked potential of hypothalamic arcuate nucleus induced by microinjection of glutamate and glycine into the ventrolateral part of the nucleus of the solitary tract of rabbit and its possible mechanism And meaning. The main results are as follows:
