Summary
Cochlear implants (CI) improve hearing but outcomes vary due to brain changes. This study offers guidelines for using electroencephalography (EEG) with CIs to reduce prosthesis artifacts and improve brain plasticity measurements.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Audiology
Background:
- Cochlear implants (CI) restore hearing but clinical outcomes vary significantly.
- Brain reorganization (plasticity) after CI is a key factor in outcome variability.
- Objective measures are needed to study post-implantation brain plasticity.
Purpose of the Study:
- To provide guidelines for designing electroencephalography (EEG) experiments with CI users.
- To offer technical guidance for recording neural responses in the presence of CI artifacts.
- To address challenges in detecting and removing CI-induced artifacts from EEG data.
Main Methods:
- Comprehensive literature review on EEG-CI artifact removal.
- Analysis of existing techniques for artifact reduction.
- Development of experimental design recommendations for EEG-CI studies.
Main Results:
- Identified significant challenges in artifact removal from EEG recordings in CI users.
- Proposed a guideline to minimize CI artifacts during EEG acquisition.
- Highlighted the need for standardized reporting of EEG-CI findings.
Conclusions:
- Standardized EEG recording and artifact removal protocols are crucial for reliable brain plasticity assessment in CI users.
- Improved methodologies will enhance understanding of CI's impact on neural function.
- Further research is recommended to validate artifact removal techniques and reporting standards.
