the effects of metoclopramide on ketamine-induced linguopharyngeal events exemplified by tongue retrusions , protrusions , and swallowing acts were tested in ketamine-anesthetized rats mounted on a stereotaxic frame with the tip of the tongue tied to a force displacement transducer to monitor retrusion and protrusion and a pressure transducer inserted into the mouth at the level of the soft palate to monitor swallowing .
