Models of Neural Responsiveness to Electrical Stimulation

In principle, electrical stimulation of the cochlea is a simple process. Intracochlear electrodes, when stimulated, create electrical field patterns within the cochlea. In the vicinity of the neural elements, these fields appear as extracellular voltage gradients or profiles that are continuous along the entire length of the neurons. These extracellular voltage fields produce current flow into and out of the neural elements depending on the local impedances of the neural membranes. If the neural elements are sufficiently depolarized, action potentials are generated that propagate along each cell’s axon to the cochlear nucleus. Globally these events occur simultaneously, but in varying degree, across a population of nerve cells, producing a group or ensemble of neural responses to the stimulation.
