| Outline of Final Research Achievements |
The swallowing center which provides sequential pharyngeal and laryngeal movements is located mainly in the medulla oblongata, and overlapped with the medullary respiratory neuronal networks. To evaluate whether the medullary respiratory neurons contribute to regulating swallowing behavior and thus play a critical role in the network plasticity due to the electrical stimulation of the larynx, we investigated activity and distribution of the respiratory-related neurons in the ventrolateral medulla during swallowing. Various types of respiratory neurons were recorded in this region and changed their activity during swallowing in a type specific manner, suggesting that the medullary swallowing networks can share the respiratory neuronal networks in the medulla oblongata.
