The effect that design of the nucleus intracochlear electrode array and age of onset of hearing loss have on electrically evoked compound action potential growth and spread of excitation functions

The purpose of this study was to investigate how design changes in Cochlear Nucleus cochlear implants (CIs) (CI24M, CI24R, CI24RE and CI422) affected electrode impedance and ECAP measures, and to determine if these design changes affected post-lingually deafened adults and children with congenital hearing loss in a similar way.
