本文研究了大鼠前庭神经核中参与前庭-胃肠反射反应的神经元的结构和功能特点。在孤束核的“胃”区显微注射辣根过氧化物酶溶液后，在前庭内侧核的尾侧部分发现逆行标记的细胞体。电刺激这些神经元导致胃张力降低。同时记录呼吸停止。结果表明，前庭神经元的激活可以引起内脏系统的协调变化，这是呕吐反应所特有的。(C)1998由Elsevier Science爱尔兰有限公司出版。保留所有权利。
Some structural and functional peculiarities of the rat vestibular nuclei neurones involved in realisation of vestibular-gastrointestinal reflectory reactions were studied. After microinjection of a horseradish peroxidase solution in the 'gastric' area of the nucleus tractus solitarius, retrogradely-labelled cell bodies were found in caudal part of the medial vestibular nucleus. Electrical stimulation of these neurons resulted in the decrease of gastric tone. The respiratory arrest was registered simultaneously. The results suggest that activation of the identified vestibular neurons can induce coordinated changes in visceral systems which are peculiar to a vomiting reaction.
