Summary
Experiments were performed on 4 dogs with gastric fistulae and electrodes implanted into the cranial cavity. The author studied the effect produced by the changes of the functional state of cerebral cortex under the effect of direct current on the gastric contractions, caused by stimulation of its mechanoceptors.
In stimulation of the cerebral cortex by direct current the contractions of the stomach changed in relation to the polarity of the stimulus. In the majority of experiments anode caused an increase of the amplitude of gastric contractions (63%). A reverse effect occurred in 4% of the experiments. The changed reflex persisted for a prolonged period of time after the termination of stimulation. In the greater number of the experiments the cathode reduced the motor function of the stomach.
