Abstract

The change of operating point (OP) of outer hair cell mechano-transduction could be determined from the change of the 2nd harmonic of the cochlear microphonic (CM) following a calibration to determine its initial value. To perturb the OP, a constant force was applied to the bony shell of the cochlea using a blunt probe. orce applied over the scala tympani increased the OP. During constant force of the CM underwent a slow partial recovery toward the initial level. Removing the force again initiated a change of 2nd harmonic, which returned to the control level. These data indicate an active mechanism for OHC transduction OP to dynamically be controlled at its normal position.
