新西兰大白兔将霍乱毒素HRP注射到颈动脉窦近端的颈动脉窦神经中。存活3~5d后麻醉，用乙醛溶液固定脑组织。横切面在雪橇切割机上切开，切片用四甲基联苯胺法反应。HRP阳性纤维在听结节水平进入同侧延髓背外侧，与孤束相连。阳性纤维主要见于延髓的四个区域：孤束核的尾侧2/3，位于孤束核的背外侧区，在其连合部的尾侧，在三叉神经脊核的背外侧侧，在孤束的腹侧和腹外侧区(延伸到孤束核之外)，以及延髓腹外侧区。(C)1999 Elsevier Science B.V.保留所有权利。
In New Zealand white rabbits, cholera-toxin HRP was injected into the carotid sinus nerve just proximal to the carotid sinus. After survival periods of 3-5 days the rabbits were anesthetized and the brain fixed with aldehyde solution. Transverse sections were cut on a sledge microtome and the sections reacted with the tetramethylbenzidine procedure. HRP-positive fibers entered the ipsilateral dorsolateral medulla at the level of the acoustic tubercle, joining the tractus solitarius. Positive fibres were found principally ipsilaterally in four regions of the medulla: in the caudal two thirds of the nucleus tractus solitarius, in its dorsolateral regions and, more caudally, in its commissural subdivision; in the dorsolateral aspect of the spinal nucleus of the trigeminal nerve; in the region ventral and ventrolateral to the tractus solitarius (extending beyond the nucleus tractus solitarius); and in the ventrolateral medulla oblongata.
