Cochlear microphonics was observed which reversed with change in polarity of stimuli suggestive of auditory neuropathy (Fig 6, 7).
7,8] They found that perfusion of air into the scala tympani resulted in a drastic decrease in the cochlear microphonics and in the amplitude of the compound action potential.
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.
