An Instrumented Cochlea Model for the Evaluation of Cochlear Implant Electrical Stimulus Spread
A 3D-printed physical cochlea model with integrated sensing wires is presented, to evaluate the stimulation current spread of a cochlear implant (CI) in a cochlea. These wires are independent from the stimulating electrodes of a CI. Therefore, the measured current spread signals are not influenced by electrode-electrolyte interface potential near the CI, which is an important issue for conventional measurements that causes missing information in current spread distribution in a cochlea. This physical cochlea model provides an objective platform for comparing different CIs, as well as different stimulation modes and configurations, thus potentially offering optimized setup for specific CI patients...

Effect of Tissue Heterogeneity on the Transmembrane Potential of Type-1 Spiral Ganglion Neurons: A Simulation Study
Electric field applied by cochlear implants stimulates the intact type-1 spiral ganglion neurons (SGNs) in the Rosenthal’s canal of the human cochlea. As a result, transmembrane potential of the SGNs exceeds threshold value and fires the action potential through the... Read more
