To investigate the viscerotopic distribution of the cells of origin of preganglionic vagus nerve in rats, Fluoro-Gold was injected into various visceral tissues. After injections into the gastroesophageal junction and the gastric corpus, labelled cells were localized in the medial half of the dorsal motor nucleus of the vagus (dmnX). Cells in the nucleus ambiguous (nA) were also labelled after injections into the gastroesophageal junction. After injections into the pancreatic head and the celiac plexus, labelled cells were located bilaterally in the lateral part of the caudal dmnX. In the rostral dmnX, however, the pancreatic head was represented in the medial segment. After injections into the lung, duodenum, liver and ascending colon, no labelling was observed in the brainstem.
为研究大鼠迷走神经节前神经元的起源细胞在内脏的分布情况，将荧光金注射到不同的内脏组织中。向胃食管交界处和胃体注射后，标记细胞定位于迷走神经背运动核（dmnX）的内侧半部。向胃食管交界处注射后，疑核（nA）中的细胞也被标记。向胰头和腹腔神经丛注射后，标记细胞双侧位于尾侧dmnX的外侧部。然而，在头侧dmnX中，胰头的代表区域在内侧节段。向肺、十二指肠、肝和升结肠注射后，在脑干中未观察到标记。
