描述了从山羊和猫的胃中的受体以及猫的尿液中的膀胱受体的单个纤维中分离和记录的方法。胃感受器被胃的被动扩张和主动收缩所兴奋，并慢慢适应持续的指压。在山羊的食管沟区域和猫的胃的胃部和幽门区发现了胃受体。山羊部分胃传入纤维的传导速度为2~12m/s。在膀胱被动扩张和主动收缩时，冲动被记录在盆丛中的单个传入纤维中。等张和等长记录条件下的放电与膀胱内压有关。膀胱中的感受器正在慢慢适应。结果表明，胃和膀胱感受器是与肌纤维串联的张力记录器。
Methods are described for isolating and recording from single fibers from receptors in the stomach of the goat and cat and from urinary vesical receptors in the cat. Gastric receptors were excited by passive distension and active contraction of the stomach and adapted slowly to sustained digital compression. Gastric receptors were found in the esophageal groove region in the goat and in the cardiac and pyloric regions of the stomach in the cat. The conduction velocities in some of the gastric afferent fibers in the goat were 2-12 m/sec. Impulses were recorded in single afferent fibers in the pelvic plexus during passive distension and active contraction of the urinary bladder. The discharge under isotonic and isometric recording conditions was related to the intra-vesical pressure. The receptors in the bladder were slowly adapting. It was concluded that the gastric and bladder receptors were tension-recorders in series with the muscle fibers.
