Pseudorandom vestibular rotatory stimuli covering the normal head movement range (0–6 Hz) and power spectrum analysis techniques are used to clinically evaluate the vestibulo-ocular reflex (v.o.r.). Measurements of compensatory eye movements are recorded during fixation of a stationary target, during fixation of a target moving with the subject and in darkness. The gain above 3 Hz quantifies vestibular function under all these conditions. A frequency-dependent v.o.r. asymmetry indicates the side of a peripheral lesion. The fixation suppression curve at medium frequencies quantifies visual-vestibular interaction. Thus the new test is a powerful diagnostic tool applicable to disease of the labyrinth and central vestibular pathways. This test is evaluated on monkeys before unilateral labyrinthectomy and for an extended period of time after.
