Summary
This study shares a large dataset of electrocochleography (ECochG) signals from cochlear implant patients. The data and algorithms aim to improve the analysis of these crucial inner ear function measurements.
Area of Science:
- Audiology
- Neuroscience
- Biomedical Engineering
Background:
- Electrocochleography (ECochG) measures inner ear potentials, reflecting residual cochlear function.
- Intracochlear ECochG in cochlear implant (CI) recipients offers direct electrophysiological insights.
- Analyzing ECochG signals presents significant challenges for researchers.
Purpose of the Study:
- To provide a comprehensive dataset of intracochlear ECochG signals for the scientific community.
- To share algorithms for raw data acquisition, signal processing, and Deep Learning analysis.
- To facilitate objective analysis and interpretation of ECochG data in CI users.
Main Methods:
- Collected 4,924 intracochlear ECochG signals from 46 ears with cochlear implants.
- Recorded data during and after electrode insertion, including subjects with residual hearing.
- Developed and applied Deep Learning algorithms for objective signal analysis.
Main Results:
- A large, well-characterized dataset of intracochlear ECochG signals is now publicly available.
- The dataset includes associated demographic, audiological, and clinical data.
- Algorithms for signal processing and Deep Learning-based analysis are provided.
Conclusions:
- This dataset and associated tools will advance research in cochlear implant audiology.
- Improved ECochG analysis can lead to better understanding of CI function and patient outcomes.
- Facilitating data sharing promotes reproducibility and innovation in the field.
