Research Abstract

In this study, I recorded swallowing induced by electrical stimulation and liquid stimulation in development stage animal and examined the developmental change of the swallowing-induced ability and swallowing pattern. In newborn animals, swallowing can induced by the weak stimulation and the swallowing number of newborn animals was increased compared with that of mature animals. It was suggested that newborn animals have high ability to induce swallowing.
