Computational models have been widely used to improve the knowledge of the current distribution behavior in cochlear implant stimulations, optimizing electrode designs and stimulation strategies. The existing models employed no or simple electrochemical interface models and took current intensity on the electrodes as input. Therefore they have...

Cochlear implants have been proved to be an effective treatment for patients with sensorineural hearing loss. Among all the approaches that have been developed to design better cochlear implants, 3D model-based simulation stands out due to its detailed description of the electric field which helps reveal the electrophysiological phenomena...

Simulation of the intracochlear potentials is an important approach to study the activation of auditory nerve fibers under electrical stimulations.However, it is still unclear to which extent the simulation results are affected by precision in reproducing the exact cochlear geometry.In this study, we address to this question by comparing the...

BackgroundIn cochlear implants, the hybrid common ground is a combination of a classic monopolarstimulation with a standard common ground. This new stimulation montage allows the current toreturn from both the non-stimulating electrodes on the electrode array and the reference electrodeplaced between the skull and scalp. In theory, this lead to...

Oticon Medical cochlear implants use a stimulation mode called Distributed All-Polar (DAP) that connects all non-stimulating available intracochlear electrodes and an extracochlear reference electrode. It results in a complex distribution of current that is yet undescribed. The present study aims at providing a first characterization of this...
