To study neural mechanisms of motion sickness in rabbits, we examined the changes of heart rate (HR) and the coefficient of variation of R-R interval (CV-RR) during two types of vestibulo-visual conflict (VVC) stimulation. One is vestibular stimulation (VS) without visual input, and the other is VS with optokinetic stimulation. After atropine injection or labyrinthectomy, the changes of HR and CV-RR during both VVC stimulations decreased. These results suggested that vestibulo-autonomic nerve reflex plays an important role in body response during VVC stimulation and this reflex reduces as the conflict vanishes.
