Abstract:
Three-dimensional (3D) computational modelling of the auditory periphery forms an
integral part of modern-day research in cochlear implants (CIs). These models consist
of a volume conduction description of implanted stimulation electrodes and the current
distribution around these, coupled to auditory nerve fibre models. Cochlear neural
activation patterns can then be predicted for a given input stimulus. The objective of
this article is to present the context of 3D modelling within the field of CIs, the
different models and approaches to models that have been developed over the years, as
well as the applications and potential applications of these models. The process of
development of 3D models is discussed, and the article places specific emphasis on the
complementary roles of generic models and user-specific models, as the latter is
important for translation of these models into clinical application.
