Computational Modelling



3D FEM Model of a Human Cochlea and a Cochlear Implant

  • 3D finite element method (FEM) models of human cochleae to simulate the voltage distribution in the cochlea when stimulating with a cochlear implant (CI)
  • The 3D model can be customized based on landmarks from CBCT imaging data to represent individual patients
  • Voltage distributions can be used to study the activation of the auditory nerve by a CI

3D FEM Model of Auditory Nerve and Auditory Nerve Implant

  • 3D FEM model of a human cochlea and auditory nerve to predict the voltage spread with the novel auditory nerve implant (ANI)
  • The ANI delivers intraneural stimulation to the auditory nerve through penetrating electrodes

Auditory Nerve Fiber models

  • Phenomenological and physiological models of auditory nerve fibers stimulated acoustically, electrically, or with electric-acoustic stimulation (EAS)
  • Neuron models can be coupled to FEM models for realistic current input

Electrophysiology and Neural Health

  • Models of neural degeneration to study the effect on thresholds, evoked potentials, or signal transmission
  • A model of the acoustically or electrically evoked compound action potential (aCAP/eCAP) measured through intracochlear electrodes

Auditory Experiments Simulations

  • Computational models to simulate performance of cochlea implant users in different auditory experiments
  • Objective measurements of speech intelligibility from neural spike activity
