In 20 animals, swallowing interneurons contralateral to the muscimol injection side were simultaneously recorded extracellularly and their firing rates were analyzed during swallowing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Integrated VNA and HNA to the injection side decreased to 49.0\u2009\u00b1\u200916.6% and 32.3\u2009\u00b1\u200917.9%, respectively. However, the VNA on the uninjected side showed little change after muscimol injection. Following local inhibition, 11 out of 20 contralateral swallowing interneurons showed either increased or decreased of their respective firing discharge during evoked\u2010swallowing, while no significant changes in activity were observed in the remaining nine neurons.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The neuronal networks underlying the swallowing
