A parallel-swing ENG study in rabbits led to two investigative conclusions: (a) for experimental purposes the parallel swing test must be performed with monocular, both horizontal and vertical leads, and (b) such studies must be performed in a darkened room. Following surgical bilateral "immobilization" of the cupulae of the horizontal semicircular canals, horizontal nystagmus induced in the parallel-swing test is probably generated by the otolithic system.
