Abstract

Seventy-one dorsal raphe (DR) neurons of the cat were antidromically activated by electrical stimulation of the medial forebrain bundle (MFB). It was found that not a small number of DR neurons send their axons contralaterally. Seven out of 67 DR neurons (10.4%) responded to stimulation of both sides of MFB. Positive collision test for the bilaterally evoked responses indicates that single axons of these DR neurons bifurcate to innervate bilateral forebrain structures.

摘要

通过电刺激猫的内侧前脑束（MFB）对71个中缝背核（DR）神经元进行逆向激活。发现相当数量的DR神经元将其轴突发送到对侧。67个DR神经元中有7个（10.4%）对双侧MFB刺激有反应。对双侧诱发反应的正向碰撞试验表明，这些DR神经元的单个轴突会分叉以支配双侧前脑结构。
