Abstract Normal Form of Hopf bifurcaiton equation(NFE) has been used to describe a Hair bundle motion. In this talk, I will show that the NFE can also describe the mode-locking mechanism of hair bundle and NFE with noise exhibits stochastic resonance. Also, I propose that Kuramoto model can describe dynamics of the coupled hair bundles and stochastic resonance can play essential role in the detection of sound.
