The endolymphatic potential is generally positive with respect to the perilymph, though the difference varies between organs, ranging from +80 mV in the mammalian cochlea to -10 mV in fish semicircular canals (Mayer-Gostan et al.
For the inner ear, the normal function of this pump is necessary to maintain the high endolymphatic potassium concentration and the high endolymphatic potential.
Many have tried to identify the cause and based on their conclusion the probable mechanisms are microangiopathy of the inner ear, neuropathy of the cochlear nerve, a combination of both, outer hair dysfunction and disruption of endolymphatic potentials.
