Neural degeneration does not drive the anodic sensitivity seen in humans

Evidence

Duration of deafness did not influence the effect of polarity, suggesting that neural degeneration may not entirely account for the higher sensitivity to anodic stimulation observed in humans. However, the morphology of the nerve fibers and the cochlear geometry are different in the two species and may play an additional role on neural excitation (Rattay et al. 2001 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2272
