实验是在麻醉的狗身上进行的。迷走神经切开术后胃张力增高。胃张力对传出迷走神经电刺激的相位反应在这些实验中不像在猫身上那样是可分离的。然而，食道膨胀产生了明显的胃松弛反应，与猫一样，这种反应是非胆碱能和非肾上腺素能的，但迷走神经切断术消除了这种反应。这种反应被认为相当于胃在进食时的生理感受性放松。
Experiments were performed on anaesthetized dogs. Vagotomy was followed by an increase of gastric tone. The phasic responses of gastric tone to efferent vagal electrical stimulation were not separable in these experiments as they are in cats. Oesophageal distension, however, produced a marked gastric relaxatory response, which, as in cats, was non-cholinergic and non-adrenergic but abolished by vagotomy. This response is suggested to be equivalent to physiological receptive relaxation of the stomach, occurring during food intake.
