Abstract
Direct mechanical measurements of the basilar membrane in the guinea pig cochlea have revealed that a dc component of basilar membrane motion exists and shows a systematic tendency to reverse polarity close to the best frequency (BF) of the ac response. The dc component is seen in time records as a change in the mean position of the basilar membrane with the onset of the tone burst. The offset is physiologically vulnerable and is substantially reduced as the preparation deteriorates. A computer model of the basilar membrane, employing nonlinear stiffness and damping elements, shows a pattern of rectification with polarity reversal not unlike the experimental data.
