We applied wheat germ agglutinin-horseradish peroxidase (WGA-HRP) to the adventitia of the left carotid sinus of cats after tying the glossopharyngeal and the carotid sinus nerves. Forty-five to 255 neurons were labeled in the rostral pole of the nodose ganglion, through the pharyngeal branch of the vagus nerve. Transganglionic label was present only in the ipsilateral dorsal and medial subnuclei of the nucleus tractus solitarii at levels nearly rostral to the area postrema. These findings show the existence of a novel pathway from the carotid sinus, projecting via the vagus nerve, to the nucleus tractus solitarii.
在结扎猫的舌咽神经和颈动脉窦神经后，我们将小麦胚芽凝集素-辣根过氧化物酶（WGA-HRP）应用于猫左颈动脉窦的外膜。通过迷走神经的咽支，在结状神经节的头端极标记了45至255个神经元。跨神经节标记仅存在于孤束核的同侧背侧和内侧亚核中，位于近最后区头侧的水平。这些发现表明存在一条从颈动脉窦经迷走神经投射到孤束核的新通路。
