Licking behavior of rats appeared to be interrupted periodically for about 20 ms. Behavioral and electrophysiological evidence is presented which indicates that during this period swallowing occurs. The hypothesis was tested that swallowing initiation depends on the volume of water that has accumulated in the oral cavity during drinking. No support for this hypothesis was obtained when the flow rate of water through the drinking tube was manipulated. Alternative hypotheses are discussed.
大鼠的舔舐行为似乎会周期性中断约20毫秒。本文提供了行为学和电生理学证据，表明在此期间会发生吞咽。对吞咽起始取决于饮水过程中口腔内积聚的水量这一假设进行了检验。当操纵通过饮水管的水流速度时，未获得对该假设的支持。文中讨论了其他替代假设。
