Аннотация
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.
