摘要：

Spontaneous swallowing or the buccopharyngeal phase of swallowing evoked by electrical stimulation of the superior laryngeal nerve was accompanied by a pronounced decrease of sympathetic activity in the cardiac nerve. This reduction of sympathetic activity was not related to other influences such as postinspiratory inhibition or baroreceptor-mediated inhibition. Intraceullular recordings from sympathetic preganglionic neurones revealed hyperpolarization during the buccopharyngeal phase of swallowing, possibly due to postsynaptic inhibition. © 1990.
