| Outline of Final Research Achievements |
Chemical stimulation of the pharynx is effective in eliciting swallowing. We investigated the effect of taste solutions on the elicitation of swallowing in human. The results indicated that stimulation of the pharyngeal region with sour solutions facilitates swallowing, suggesting that the facilitation may be due to increases of sensory inputs. Moreover, we tested in anesthetized or unanethetized rats whether there were particular neuron activities in cortical area and brain stem during feeding by using multi-channel neural recordings and stimulation applications.
