dc.description.abstract | Objective: To investigate electrically evoked auditory cortical responses (eACR) elicited from the stimulation
of intracochlear electrodes based on individually fitted stimulation parameters in cochlear implant (CI) users.
Design: An eACR setup based on individual fitting parameters is proposed. A 50-ms alternating biphasic
pulse train was used to stimulate apical, medial, and basal electrodes and to evoke auditory cortical
potentials (N1-P2 complex).
Study sample: The eACR setup proposed was validated with 14 adult CI users.
Results: Individual and grand-average eACR waveforms were obtained. The eACR amplitudes were lower
in the basal than in the apical and medial regions. Earlier N1 latencies were found in CI users with lower
maximum comfortable loudness levels and shorter phase duration in response to apical stimulation, while
medial and basal stimulation resulted in earlier N1 latencies and larger N1-P2 amplitudes in users with
longer CI experience.
Conclusions: eACR could be elicited by direct intracochlear stimulation using individual fitting parameters
with a success rate of 71%. The highest cortical peak-to-peak amplitudes were obtained in response to
apical stimulation. Unlike the P2, the N1 component appeared to be a consistent cortical potential to
determine eACR and gain knowledge of the auditory processing beyond the cochlea in CI users. | es |
