Approach To The Generation Centre Of Nystagmus Alternans By Means Of Drug Tests

Abstract

Barbiturates and chlorpromazine stop nystagmus alternans temporarily. During the time of action of the barbiturate nystagmus can be elicited in the patient by caloric stimulation, whereas during the action of chlorpromazine there is no caloric reaction. From these observations the conclusion can be drawn, that the generation centre of the nystagmus alternans is above the primary vestibular reflex-arch.
