The authors studied on the influences of the stimulation of N. trigeminus-by dental grinding and electrical stimulation of tooth-upon the gastric movement of unanaesthetic rebbit, using so-called "balloon" method. The results were obtained as follows: 1) Each case stimulated by dental grinding and electrical stimulation, the excitatory effects were observed by the weak stimulation, and the inhibitory effects by the strong stimulation. 2) After the administration of Atropine, the excitatory effect disappeared by the weak stimulation, and the inhibitory effect was observed by the stong stimulation. 3) After the administration of Yohimbin, the inhibitory effect disappeared by the strong stimulation, and the excitatory effect was observed by the weak stimulation. Form the above mentioned results, the authors conclude the excitatory and inhibitory effect by the stimulation of N. irigeminus take two courses: 1) N. trigeminus-Medulla-N. vagus and 2) N. trigeminus-Medulla-Diencephalon-Medulla-Spinal-splanchinic nerve.
