Finally, these data were associated with the intracochlear conductivity paths calculated according to the
potential distribution data acquired with electrical field imaging.
Chapter 4
focuses on the use of cochlear
implants to measure the effectiveness of the electrode-neural interface using the electrically evoked action
potentials of neurons in the cochlea. The effects of parameter setting on SOE measurements are described.
Chapter 5
presents an analysis of the predictability of fitting levels based on a review of the clinical levels of
151 cochlear implants recipients. The T- and M-level percentiles, their mutual relationship and their course
during the first year after implantation are presented, and applicable predictive models for T- and M-levels
are obtained from the dataset.
Chapter 6
describes the differences along the array of T- and M-levels and
their relationship with intrascalar position. The insertion depth and distance to the modiolus are both taken
into consideration. The focus of this study is the differences in levels along the array, especially towards the
basal end of the array.
