The terminal nerve ganglion cells project to the olfactory mucosa in the dwarf gourami.
Single- and double-label immunocytochemical studies were conducted using antisera to salmon gonadotropin-releasing hormone (sGnRH) and molluscan cardioexcitatory peptide (FMRFamide) to determine whether terminal nerve ganglion cells project to the olfactory mucosa in the dwarf gourami, Colisa lalia. Both peptides were present in terminal nerve ganglion perikarya and fibers in brain and nasal cavity. Labeled fibers were present in the olfactory nerve and could be traced to the olfactory mucosa. All terminal nerve ganglion cells contained both sGnRH and FMRFamide-like peptides. This study suggests that the terminal nerve ganglion cells can influence both brain and chemoreceptive structures.
