Vertigo is produced by some disturbance in the functions of orientation and equilibration which results in a disturbed conception of our position in space, and is objective when objects about the patient seem to move, and sabjective when patients feel themselves to be in motion.
The function of orientation is a nice sense presided over by the vestibular apparatus; it is intimately associated with equilibration and brings this about by impressions through Deiters' nucleus oculomotor centers on one hand and to the motor neurons of the cord on the other.
Physiologists are divided into those who assert that all vertigo is essentially auditory in location, and those who believe that vertigo may result from disturbance of the cerebellum, entirely without the intervention of the vestibule and canals. The weight of opinion, however, seems to be in favor of the former view.
We know that the impulses conveyed from the eyes by way of muscle-controlling nerves are correlated in the cerebellum, and that
