Abstract
In 7 dogs, the vestibular apparatus of the inner ear was surgically removed and it was observed that the emetic response to certain poisons was impaired. Thus, it was concluded that the inner ear was part of the normal mechanism for vomiting in response to poisons, and that a physiological function of the inner ear was to facilitate the emetic response to poisons. The mechanism whereby the vestibular apparatus facilitated the emetic response to poison was the basis of motion sickness. Thus, motion sickness could be considered the result of activation, by motion, of a mechanism that normally functioned to facilitate vomiting in response to poisons.
