Vestibular evoked myogenic potentials (VEMPs) represent a relatively recent subject of investigation in regard to diagnosing specific vestibular disorders. Numerous experimental animal models1- 3 and clinical studies4- 9 suggest that VEMPs are a vestibular-colic reflex, the afferent branch of which originates in the acoustic cells of the saccule, conducting signals through the inferior vestibular nerve. These studies have proposed hypotheses based on the possibility of VEMPs originating in the saccule but have provided no definitive proof to that effect.
