Temperature-dependence of a fast motile response in isolated outer hair cells of the guinea-pig cochlea.


Isolated outer hair cells (OHC) of the cochlea exhibit a motility which can be driven at acoustic frequencies (Ashmore, 1987). The temperature-dependence of the movement is reported here for the range 20-37 degrees C. OHC are shown to be motile at 37 degrees C. The temperature-dependence is quite weak, with Q10 = 1.33. The observation is difficult to… (More)
