To determine a possible brainstem connection with the uterus, a study with electrophysiological techniques and horseradish peroxidase (HRP) tracing was performed in the rat. Neurons of the nucleus of the tractus solitarius decreased in discharge frequency during cervicovaginal distension. HRP injections into the uterine walls resulted in the appearance of labelled cells in the nodose ganglion and in the dorsal motor nucleus of the vagus nerve. The results demonstrate a direct bidirectional vagal complex-uterus connection via the vagus nerve. Results are discussed in terms of a complex uterus control system in which the paraventricular nucleus might play an integrative role.
为确定脑干与子宫之间可能存在的联系，在大鼠身上进行了一项采用电生理技术和辣根过氧化物酶（HRP）追踪法的研究。在子宫阴道扩张期间，孤束核的神经元放电频率降低。向子宫壁注射HRP后，在结状神经节和迷走神经背运动核中出现了标记细胞。结果表明，通过迷走神经存在直接的双向迷走复合体 - 子宫连接。根据一个复杂的子宫控制系统对结果进行了讨论，其中室旁核可能发挥整合作用。
