Cochlear microphonic potential

Webcochlear microphonic Stimulus-related potential created from the outer hair cells. -70mV Difference in mV between the endolymph and the hair cells. 80mV The mV difference between the scala media and scala tympani. resting (standing) potential Term for voltage potential differences of the cochlea that can be measured from the cochlea at rest. WebThe cochlear microphonics cannot provide information about the integrity of the hair cells outside the most basal part of the cochlea and is therefore not useful for electrocochleography, and the discrimination between a negative summating potential and a broad compound action potential based on adaptation measurements is elucidated. …
