Possible implication of an efferent neuropathy in vestibular upset

This essay examines two possible mechanisms whereby a neuropathy affecting the efferent vestibular innervation may cause incoordination of vestibular afferent input to the Vestibular Integrating Centres: firstly, by loss of the normal fine control of afferent impulses; secondly, by a disruption of the sodium-potassium pump mechanism that maintains the ionic stability of the inner ear fluids.
