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. Intracellular recordings from sympathetic preganglionic neurones revealed hyperpolarization during the buccopharyngeal phase of swallowing, possibly due to postsynaptic inhibition.
自发吞咽或通过喉上神经电刺激诱发的吞咽的口咽期，伴随着心脏神经中交感神经活动的显著降低。交感神经活动的这种降低与其他影响因素无关，如吸气后抑制或压力感受器介导的抑制。来自交感神经节前神经元的细胞内记录显示，在吞咽的口咽期出现超极化，这可能是由于突触后抑制所致。
