两个实验检查了喉神经（LN）控制生产的超声波和他们的起源核在147个10天大的Sprague-Dawley大鼠幼崽。单侧和双侧切断下LN使超声检查降低到无法检测的水平。切断单侧或双侧上级淋巴结可降低声压级，降低频率，并增加超声的基频。辣根过氧化物酶的逆行运输表明，下LN的传出轴突起源于疑核（NA）背侧结构的细胞，而上级LN的传出轴突起源于疑核的腹侧结构。因此，不同方面的生产小狗超声波似乎是由不同的神经元亚群的NA。(28参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Two experiments examined the laryngeal nerves (LNs) controlling the production of ultrasounds and their nuclei of origin in a total of 147 10-day-old Sprague-Dawley rat pups. Unilateral and bilateral transections of the inferior LN reduced ultrasounds to undetectable levels. Transecting the superior LN either unilaterally or bilaterally reduced the sound pressure level, reduced the rate, and increased the fundamental frequency of the ultrasounds. Retrograde transport of horseradish peroxidase indicated that the efferent axons in the inferior LN arise from the cells of the dorsal formation of the nucleus ambiguus (NA) and that efferents in the superior LN originate from the ventral formation of the NA. Therefore, different aspects of the production of pup ultrasounds appear to be controlled by distinct neuronal subpopulations of the NA.(28 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
