Summary
In previous experiments on frogs and dogs, reflex effects on the stomach had been shown to follow mechanical or electrical stimulation of the heart.
In the present work, an attempt was made to trace the path of this reflex. In a frog, both vagus nerves were divided at the site of their exit from the brain. It was found that stimulation of the heart no longer affected the gastric movements.
The reflex also disappeared when the medulla was destroyed, while the vagi were left intact.
Therefore, the cardio-gastric reflex is effected through the vagi, and the medulla is the central link of the reflex arc.
