Several animals, in particular, lizards, possess a specialized hearing mechanism: internally coupled ears (ICE), where the tympanic membranes are coupled through a large mouth cavity. An analytically soluble model of internally coupled ears has been developed. Together with a numerical eigenfrequency analysis of the reconstructed mouth cavity, it allows for a realistic description of tympanic vibrations. The resulting segregation of frequency ranges in the ensuing neuronal processing for internal time (low-) and amplitude differences (high-frequency range) has been modeled as well. A systematic analysis of best frequencies for different animals completes the study of internally coupled ears. For an arbitrary sensory system, we then analyze neuronal connectivity patterns that optimally reconstruct the corresponding sensory inputs. Finally, formation of these neuronal representations is modeled as a multimodal learning process.
