A form of vestibular nystagmus that occurs when the body is rotated and then the rotation is stopped. If, while sitting upright in a chair that can be swiveled, the body is rapidly rotated to the right, the nystagmus during rotation has its slow component to the left. When the rotation stops, the slow component is to the right. Stimulation of the semicircular canals causes this type of nystagmus, and it is a normal reaction.
