Abstract
Electrical stimulation of the cochlea may excite residual inner hair cells, either by direct electrical stimulation or through a mechanical event. Hair cell mediated responses of the auditory nerve to electrical stimulation were estimated from forward masking of the compound action potential evoked by an acoustic probe. Masking by a fixed electrical masker peaked for probes equal in frequency to the pulse repetition rate and its second harmonic, suggesting a spatially tuned profile of excitation within the cochlea. Furthermore, the tuning curves for masking of a fixed acoustic probe peaked for masker pulse rates close to the frequency of the probe. A secondary peak of masking was commonly seen for electrical stimulation at one half of the probe frequency, suggesting masking of the probe by the second harmonic of the electrical stimulus. These results suggest that pulsatile stimulation at the base of the cochlea generates a spectrally rich mechanical disturbance in which each component propagates to its place of resonance in the cochlea.
