Summary
This study introduces a large dataset of microelectrode recordings (MER) from deep brain stimulation (DBS) procedures. The dataset aids in precisely mapping brain structures for improved neurological disorder treatments.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Data Science
Background:
- Accurate intraoperative localization of subcortical brain structures is crucial for effective deep brain stimulation (DBS).
- Limited availability of open-access microelectrode recording (MER) datasets hinders research and development in this area.
Purpose of the Study:
- To present a comprehensive dataset of processed MER recordings from patients undergoing DBS procedures.
- To facilitate advancements in subcortical structure classification, analysis of pathological neuronal activity, and development of novel DBS targeting strategies.
Main Methods:
- Collected 6,646 processed MER recordings from 132 patients with various neurological disorders.
- Applied automated machine learning for artifact rejection and band-pass filtering.
- An experienced electrophysiologist annotated key basal ganglia structures (striatum/putamen, GPe, GPi).
Main Results:
- A substantial, high-quality dataset of MER signals and annotated brain structures is now available.
- The dataset includes detailed metadata and the full processing pipeline.
- The data supports diverse research applications, including semi-supervised learning for structure classification.
Conclusions:
- The released dataset and processing pipeline address the scarcity of open MER data.
- This resource is expected to accelerate research in DBS targeting and subcortical neurophysiology.
- It will enable the development of more precise and effective treatments for neurological disorders.
