Some previous investigators have reported controversial results in the stomach movement in response to labyrinthine stimulation (1). The purpose of the present study was to investigate the influence of vestibular stimulation on the stomach movement and respiration in anesthetized cats, and to investigate the differences between increased and decreased responses of the stomach movement. This study used an electrophysiological technique: a bipolar stainless-steel stimulating electrode with a tip diameter of 20 microns introduced chronically into the anterior and/or lateral semicircular canal (2). The intragastric pressure was recorded by using a balloon-transducer system. Respiration was recorded by measurement of the thorax. When the peripheral labyrinth was stimulated, we found conflicting results in that the pressure in the stomach increased several times and sometimes decreased. Respiration usually became irregular or intensified. It seems that forced respiration may be involved in vestibular vomiting but we were unable to induce vomiting.
一些先前的研究者报告了关于胃运动对迷路刺激的反应的有争议的结果(1)。本研究的目的是研究前庭刺激对麻醉猫胃运动和呼吸的影响，并研究胃运动反应增强和减弱之间的差异。本研究采用了一种电生理技术：将尖端直径为20微米的双极不锈钢刺激电极长期插入前和/或外侧半规管(2)。通过气囊换能器系统记录胃内压。通过测量胸部记录呼吸。当刺激外周迷路时，我们发现了相互矛盾的结果，即胃内压力有时会增加几倍，有时会降低。呼吸通常会变得不规则或增强。似乎强迫呼吸可能与前庭性呕吐有关，但我们无法诱发呕吐。
