The Barany Chair
Even after the chair has come to a full stop, fluid within the ear continues to move, and the participant may feel he/she is still spinning. This ongoing sense of motion may lead to occular nystagmus, an oscillating motion of the eye. Even though the body is not moving, sensors in the brain indicate that it is still spinning. To compensate, the eyes attempt to fix on stationary objects to stabilize themselves.
