[The influence of stimulation of the glossopharyngeal nerve on the gastric inhibitory and excitatory motor reflexes (author's transl)].

The influence of electrical stimulation of central cut end of the glossopharyngeal nerve on the vagal inhibitory and excitatory reflexes of gastric movements were investigated. Frogs and bullfrogs were employed in all experiments under urethan anaesthesia and also immobilized with 1% solution of d-tubocurarine chloride. Bilateral splanchnic nerves were previously severd, and so the stomach was innervated through the vagus nerves only. 1. The vago-vagal inhibitory reflex of gastric movements was depressed or abolished during the maintenance of stimulation of the glossopharyngeal nerve. But, the vago-vagal excitatory reflex of gastric movements was augmented in the one example and in the other example it was depressed during the glossopharyngeal stimulation. 2. The labyrintho-vagal excitatory reflex of gastric movements was excited during the maintenance of stimulation of the glossopharyngeal nerve.
