Recording of the cochlear microphonic potential with surface electrodes.
Electroencephalography and Clinical Neurophysiology
|March 1, 1976
Summary
Researchers recorded the cochlear microphonic potential in humans using surface electrodes. This potential, crucial for hearing, was present in neural hearing loss but absent in sensory hearing loss.
Area of Science:
- Auditory Neuroscience
- Otoacoustic Emissions
- Human Physiology
Background:
- The cochlear microphonic potential (CMP) reflects outer hair cell function in the cochlea.
- Distinguishing CMP from neural responses and artifacts is crucial for accurate audiological assessment.
- Previous methods for CMP recording in humans have limitations.
