Recording eye movements and vestibular tests utilizing EEG equipment

Abnormalities of spontaneous eye movements occur frequently in patients with neurological diseases, and abnormalities of eye movements induced by vestibular and optokinetic stimulations have great diagnostic value. Their amplitude, frequency, duration, direction, and rhythmicity can be graphically recorded utilizing EEG equipment, and their speed can be easily calculated. The author emphasizes that eye movements can and should be studied in EEG laboratories, since neurologists are well prepared for the interpretation of the electrooculographic (and electronystagmography) data.
