| 摘 要： | 在３０只大鼠骶_１（Ｓ_１）脊神经节上共记录到１８２个对躯体及（或）内脏神经电刺激发生反应的神经元。其中７４个神经元既对阴部神经（Ｐｕ）刺激反应，也对盆内脏神经（Ｐｅ）刺激反应。Ｐｕ刺激引起的动作电位的传导速度（３８．１ｍ／ｓ）显著快于Ｐｅ刺激引起的动作电位的传导速度（２１．９ｍ／ｓ）。Ｐｕ和Ｐｅ刺激引起的动作电位可互相碰掉。结果提示，躯体与内脏输入可通过分叉初级传入，在同一个Ａ型脊神经节神经元上会聚。

| Abstract: | One hundred and eighty two neurons were recorded from S_1 spinal ganglion in 30 rats.Of them, 74 neurons responded to stimulation of both pudendal(Pu)and pelvic(Pe)nerve.Conduction velocity of action potentials induced by Pu stimulation (38. 07 m/s) was significantly faster than that of Pe stimulation induced ones (21. 84 m/s). The action potentials evoked by Pu and Pe stimulation could be collided each another.These results indicate that somatic and visceral input may converge on single type A spinal ganglion neurons via dichotomizing primary afferents. |
