Electrical stimulation of labyrinths and vestibular reactions.

Stimulation of the labyrinth in rabbits and guinea pigs with ascending (cathode) or descending direct current (anode) induced deviation and nystagmus of the eyes, head turn and tilt, and other reactions. Anodization of both labyrinths was followed by the disappearance of reflexes, suppression of vestibular reactions to adequate stimulation, and loss of swimming ability. The state of animals returned to normal after breaking the electric circuit.
