FIG. 5.
(Color online) (a) The mechanical sensitivity of the hair bundle χM versus the amplitude of external force F0 for the indicated values of the parameter α and βL = 0.5. The frequency of external force, fs, was tuned to the characteristic frequency of spontaneous oscillation (fs = f0), also indicated in the figure legend. (b) Contour plot of the mechanical sensitivity for various values of α and fs. Other parameters are: F0 = 0.1 pN and βL = 0.5.
