It is possible that our 1974 report has not been cited because it appeared in The Laryngoscope,5 although presentation was made at the Eighth International Congress of Electroencephalography and Clinical Neurophysiology in 19736 and the study was mentioned later in a neurology review.7Briefly, electronystagmography (ENG) was applied to patients with several motor neuron diseases (MND) (mainly, of course, ALS).
