| Outline of Final Research Achievements |
We first examined the contribution of the respiratory neurons in the parafacial respiratory group in the medulla, which can control the expiratory phase of breathing, to the swallowing regulation, in order to assess whether the respiratory neuronal networks could participate in the swallowing central pattern generation. In addition, we tested for effects of electrical stimulation of the neck to the swallowing reflexibility as well as respiratory rhythmogenesis. Consequently, our data suggested that the neurons of the parafacial respiratory group may contribute to the regulation of swallowing and that the surface electrical stimulation of the neck could modulate the swallowing central pattern generator in the medulla resulting in improvement of the laryngeal sensation to elicit swallowing.
