| Outline of Final Research Achievements |
The neural mechanism for salivary secretion induced by mastication and oral senses was investigated by electrophysiological techniques in the rat. As the result, we found that oral senses are cue sign for starting and determining patterns of both mastication and salivation. This suggests that salivation is not a result of mastication or oral sensory information. Secreted saliva dissolves foods and helps to make sense of taste, affecting taste quality and intensity. Moreover, saliva protects taste receptors in the oral cavity. Mastication, salivation, and oral senses are affected each other.
