Single-unit recordings were obtained from the vascularly isolated Krebs-Henseleit-perfused carotid sinus of the rabbit and cat, and the results were compared with those obtained previously from the monkey and dog. Carotid sinus pressure was altered using static pressure steps. There was a highly significant correlation between resting arterial pressure and carotid sinus baroreceptor threshold pressure. The baroreceptors of the monkey and rabbit had a significantly lower threshold than those of the dog and cat. The baroreceptors of the monkey had a significantly lower gain than those of the three nonprimates. This is the first study in which baroreceptor activity has been studied under the same experimental conditions in four different species.
从兔和猫的经血管分离并经Krebs-Henseleit液灌注的颈动脉窦进行单单位记录，并将结果与先前从猴和狗获得的结果进行比较。使用静态压力阶跃改变颈动脉窦压力。静息动脉压与颈动脉窦压力感受器阈值压力之间存在高度显著的相关性。猴和兔的压力感受器阈值明显低于狗和猫。猴的压力感受器增益明显低于三种非灵长类动物。这是第一项在四种不同物种的相同实验条件下研究压力感受器活动的研究。
