ABSTRACT
Possible projections of serotonin (5-HT)-immunoreactive neurons in the nodose ganglia (NG) to the nucleus tractus solitarius (NTS) were investigated in the rat using a double labeling method combining retrograde transport and 5-HT immunohistochemistry. After injection of a complex of colloidal gold-apo-horseradish peroxidase into the medio-caudal and commissural parts of the NTS, most of the 5-HT-immunoreactive neurons were found to be labelled by the gold complex. The present study provides direct evidence for the existence, in the rat, of a serotonergic NG-NTS system. This system may be involved in the regulation of blood pressure and vigilance states.
