Electronystagmographic findings in central nervous system disease.
A helpful central sign on electronystagmography with eyes closed is hyper-excitability on a caloric test. Another sign is consistent nystagmus in the presence of normal calorics. With eyes open, calibration overshoot, gaze nystagmus, pendulum tracking, failure of tracking a pendulum were by far the most common central abnormality in the experience of the author.
