Speech perception among cochlear implant (CI) listeners is highly variable. High degrees of
channel interaction are associated with poorer speech understanding. Two methods for …

Variability in speech perception scores among cochlear implant listeners may largely reflect
the variable efficacy of implant electrodes to convey stimulus information to the auditory …

Modeling data suggest that sensitivity to the polarity of an electrical stimulus may reflect the
integrity of the peripheral processes of the spiral ganglion neurons. Specifically, better …

The physiological integrity of spiral ganglion neurons is presumed to influence cochlear
implant (CI) outcomes, but it is difficult to measure neural health in CI listeners. Modeling …

Thresholds of asymmetric pulses presented to cochlear implant (CI) listeners depend on
polarity in a way that differs across subjects and electrodes. It has been suggested that lower …

Neural health is of great interest to determine individual degeneration patterns for improving
speech perception in cochlear implant (CI) users. Therefore, in recent years, several studies …

Objectives: The standard, monopolar (MP) electrode configuration used in commercially
available cochlear implants (CI) creates a broad electrical field, which can lead to unwanted …

Purpose For some cochlear implants (CIs), it is possible to focus electrical stimulation by
partially returning current from the active electrode to nearby, intra-cochlear electrodes …

Cochlear implant (CI) programming is similar for all CI users despite limited understanding
of the electrode-neuron interface (ENI). The ENI refers to the ability of each CI electrode to …

Objectives: The primary objective of this study was to quantify local (within ear) and global
(between ear) variation in the cochlear implant (CI) electrode-neuron interface (ENI) using …
