Degenerated nerve processes make anodic stimulation more effective

Evidence

Although the reason for the higher sensitivity of human CI users to anodic stimulation remains unknown, predictions from two different -among the fewcomputational models of the implanted cochlea offer possible explanations (Macherey et al. 2006 ). First, the modeling results of Rattay et al. ( 2001 ) suggest that polarity sensitivity may strongly depend on the state of degeneration and demyelination of the peripheral processes of the neurons. Specifically, the model predicts lower anodic thresholds for degenerated peripheral processes. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2273
