| Research Abstract |
The neural circuit for regulation of salivary secretion was investigated by anatomical and electrophysiological techniques. Our histochemical study shows that the superior salivatory nucleus in the lower brainstem (parasympathetic neurons innervating the submandibular and sublingual salivary glands) has heavy connection with the lateral hypothalamic area (feeding center). Our electrophysiological study also shows that main neural circuit for vigorous salivation is composed of the cerebral cortex of masticatory area, lateral hypothalamic area, and superior salivatory nucleus. It is suggested that the texture of food is recognized in the cerebral cortex that forms the command for salivation and mastication suitable for the recognized food. This salivary function may be maintained by visceral afferents form the salivary glands.
