Query: Nonlinear dynamics of the mammalian inner ear   A simple nonlinear transmission-line model of the cochlea with longitudinal
coupling is introduced that can reproduce Basilar membrane response and neural
tuning in the chinchilla. It is found that the middle ear has little effect on
cochlear resonances, and hence conclude that the theory of coherent reflections
is not applicable to the model. The model also provides an explanation of the
emergence of spontaneous otoacoustic emissions (SOAEs). It is argued that SOAEs
arise from Hopf bifurcations of the transmission-line model and not from
localized instabilities. The paper shows that emissions can become chaotic,
intermittent and fragile to perturbations.
