WebApr 4, 2024 · The cochlear microphonic (CM) is created primarily by the receptor currents of outer hair cells (OHCs) and may therefore be useful for identifying cochlear regions with impaired OHCs. WebCochlear microphonics represent the early components of the acoustic brainstem responses, occur in the 0.7–1 ms window poststimulus, and show similar waveform characteristics to the stimulus. They are a far-field reflection of auditory activity of the eighth nerve in response to an acoustic stimulus.
