Differing response properties of cervical and ocular vestibular evoked myogenic potentials evoked by air-conducted stimulation

Highlights • cVEMPs and oVEMPS were recorded simultaneously from 15 healthy volunteers and 1 patient with superior canal dehiscence (SCD) using air conducted (AC) sound over a 30 dB range. • The SCD patient had larger amplitude responses at all intensities except for the cVEMP at the loudest intensi...

Description
Summary:Highlights • cVEMPs and oVEMPS were recorded simultaneously from 15 healthy volunteers and 1 patient with superior canal dehiscence (SCD) using air conducted (AC) sound over a 30 dB range. • The SCD patient had larger amplitude responses at all intensities except for the cVEMP at the loudest intensity. • Whilst the cVEMP p13/n23 response was well fitted by a power law relationship the oVEMP n10/p16 response showed a change in gradient for the louder intensities and this may relate to differences in the pathways responsible.
