Abstract
Various simple mathematical models of the dynamics of the organ of Corti in the mammalian cochlea are analysed and their dynamics compared. The specific models considered are: phenomenological Hopf and cusp normal forms, a recently-proposed description combining active hair-bundle motility and somatic motility, a reduction thereof, and finally a model highlighting the importance of the coupling between the nonlinear transduction current and somatic motility. The overall conclusion is that precise tuning to any bifurcation is not necessary for a compressively nonlinear response over a range similar to experimental observations and that the normal form of the Hopf bifurcation is not the only description that reproduces compression and tuning similar to experiment.
