8] It is believed that mutations in GJB2 (connexin 26 gene) affect its ability to transport potassium ions and therefore regulate the endocochlear potential required for nerve impulses involved in hearing, but the mode of action is not definitively elucidated.
In typical high-frequency sensorineural hearing loss, the damage occurs primarily in the basal end of the cochlea, either to the hair cells themselves, or in the case of aging, apparently also to the endocochlear potential that serves to depolarize the hair cells when they are stimulated by sound [5].
8] They discovered that even a small amount of air in the scala vestibuli resulted in a decrease in the cochlear microphonics, the action potential, and the endocochlear potential.
