| Outline of Final Research Achievements |
It is most likely that salivary secretion during feeding is regulated by the lateral hypothalamic area (LH). We investigated the effects of melanin concentrating hormone (MCH) which is a feeding promoting peptide localized in the LH, on superior salivatory nucleus (SSN) neurons, which is the primary center of the parasympathetic nervous systems for the submandibular and sublingual glands. No SSN neurons exhibited immunoreactivity for MCH receptor and responded to MCH application. However, in the same recording neurons, orexin, a feeding promoting peptide localized in the LH as with MCH, showed excitatory responses. Therefore, regulation of SSN neuronal activity by LH would be conducted by other transmitters including orexin.
