Cochlear implant artifact attenuation in late auditory evoked potentials: a single channel approach.
Recent evidence suggests that late auditory evoked potentials (LAEP) provide a useful objective metric of performance in cochlear implant (CI) subjects. However, the CI produces a large electrical artifact that contaminates LAEP recordings and confounds their interpretation. Independent component analysis (ICA) has been used in combination with multi-channel recordings to effectively remove the...
متن کاملMinimization of cochlear implant stimulus artifact in cortical auditory evoked potentials.
OBJECTIVE To compare two methods of minimizing cochlear implant artifact in cortical auditory evoked potential (CAEP) recordings. METHODS Two experiments were conducted. In the first, we assessed the use of independent component analysis (ICA) as a pre-processing filter. In the second, we explored the use of an optimized differential reference (ODR) for minimizing artifacts. RESULTS Both IC...
متن کاملAuditory pathways' maturation after cochlear implant via cortical auditory evoked potentials.
INTRODUCTION Evaluation of cortical auditory evoked potentials in children with cochlear implants has been proven to be an effective method for assessing cortical maturation after electrical stimulation. OBJECTIVE To analyze the changes in latency values of cortical auditory evoked potentials before and three months after cochlear implant use. MATERIAL AND METHODS This was a case-control st...
متن کاملObjective Identification of Simulated Cochlear Implant Settings in Normal-Hearing Listeners Via Auditory Cortical Evoked Potentials.
OBJECTIVES Providing cochlear implant (CI) patients the optimal signal processing settings during mapping sessions is critical for facilitating their speech perception. Here, we aimed to evaluate whether auditory cortical event-related potentials (ERPs) could be used to objectively determine optimal CI parameters. DESIGN While recording neuroelectric potentials, we presented a set of acoustic...
متن کاملAuditory Evoked Potentials under Active and Passive Hearing Conditions in Adult Cochlear Implant Users
OBJECTIVES Speech perception abilities, which vary widely among cochlear implant (CI) users, are considered to be associated with the integrity of the central auditory pathways from the auditory nerve to the cortex. Therefore, auditory evoked potentials (AEPs) are used to evaluate central auditory processing, which is thought to contribute to speech perception in CI subjects. In AEPs, the P300 ...
