Abstract ; Outer hair cell (OHC) stereocilia bundle deflection opens mechanoelectrical transduction channels at the tips of the stereocilia from the middle and short rows, while bundle cohesion is maintained owing to the presence of horizontal top connectors. Here, we used a quantitative noncontact atomic force microscopy method to investigate stereocilia bundle stiffness and damping, when stimulated at acoustic frequencies and nanometer distances from the bundle. Stereocilia bundle mechanics were determined in stereocilin-deficient mice lackin ...

Many people with long hair tie their hair to ponytail-style: Closely observing the movement of their hair when they are running, I have noticed that the ponytail oscillates only...
Sound stimuli excite cochlear hair cells by vibration of each hair bundle, which opens mechanotransducer (MT) channels. We have measured hair-bundle mechanics in isolated rat cochleas by stimulatio...

The molecular gating force per channel as reflected in hair bundle mechanics is shown to equal kT/I(X) x dI(X)/dX, where I is the transducer current and X the deflection of the hair bundle....
