Effects of Electrode Position on Spatiotemporal Auditory Nerve Fiber Responses: A 3D Computational Model Study

Figure 1

Summary of the 3D computational model. (a) Details of the anatomical features for the typical axonal model and the equivalent circuit. (b) Cross-sectional image of the cat cochlea used to create the finite-element mesh model. (c) The 3D finite-element mesh model with symmetrical rotation. (d) Simplified sectional drawing showing the positions of the stimulus electrodes (A–D) and the auditory nerve fiber. (e) Example of the electric field potential inside the cochlea. OC: organ of Corti, SM: scala media, ST: scala tympani, and SV: scala vestibuli.
