Using an autoradiographic technique, the central brainstem connections of vagal visceral afferent fibres were studied. The results show that there is a large projection of vagal afferent fibres to the ipsilateral nucleus of the tractus solitarius and a smaller, sparser projection to the contralateral nucleus of the tractus solitarius. That vagal afferent fibres across the mid-line via the commissural nucleus of Cajal is confirmed. In addition, a second, more rostrally placed decussation of vagal afferent fibres is shown. Associated with this more rostral decussation is an area of termination of vagal afferent fibres in the contralateral ventromedial reticular formation. No direct projection of vagal afferent fibres to the dorsal motor nucleus of the vagus was seen.
采用放射自显影技术，对迷走神经内脏传入纤维的脑干中枢连接进行了研究。结果表明，迷走神经传入纤维大量投射到同侧孤束核，少量稀疏投射到对侧孤束核。证实了迷走神经传入纤维通过 Cajal 连合核交叉到中线。此外，还显示了迷走神经传入纤维的第二个更靠头端的交叉。与这个更靠头端的交叉相关的是迷走神经传入纤维在对侧腹内侧网状结构的一个终止区域。未观察到迷走神经传入纤维直接投射到迷走神经背运动核。
