Cochlear Nonlinearities Reflected in Inner Hair Cell Responses
The growth pattern of spectral components in a system’s output with increases in its input is revealing of its internal structure. Inferences about various properties of the peripheral auditory system from the harmonic structure of its various responses have been made since the days of Helmholtz. In contemporary work the focus has been on magnitude functions recorded for a variety of variables at differing peripheral sites. Thus basilar membrane displacement, gross cochlear potentials, inner and outer hair cell responses and discharge rates of auditory nerve fibers have all been considered. Here we study some properties of intracellular potentials recorded from inner hair cells of guinea pigs in the low frequency region of the cochlea.
