Reproducing Auditory Nerve Temporal Patterns with Sharply Resonant Filters

  • Chris van den Honert


Despite the variety of electrode configurations and signal processing strategies which have been employed for multielectrode cochlear prostheses, all such devices share one underlying intent. That intent is to determine from the incoming sound spectrum which cochlear nerve fibers should be excited at any given moment. The presence of high-frequency components causes excitation of basal fibers, while low-frequency components cause excitation of apical fibers. In some cases as many as 10 separate fiber populations may be stimulated simultaneously, each with a different intensity. This spectral-to-spatial mapping is motivated by the compelling spatial organization of the cochlea itself.
