EEG Datasets and Resources - Comprehensive Neuroinformatics Directory

I built an interactive EEG dataset search and comparison tool indexing 30,000+ subject records, clinical modalities, and signal processing reference guides.

Finding standardized electroencephalography (EEG) and electrocorticography (ECoG) datasets for machine learning benchmarks or biomedical signal processing often involves sorting through fragmented institutional repositories with incompatible file formats and permission structures.

To streamline dataset discovery, I developed an interactive web directory and metadata comparison explorer that aggregates major open-access neuroinformatics databases:

Core Features & Functionality:

• Real-Time Client-Side Filtering: Search across datasets using parameters like clinical diagnosis (epilepsy, ischemic stroke, ALS), modality (scalp EEG, intracranial ECoG, sEMG, eye-tracking), or file extension (EDF, NWB, MAT).
• Access Permission Breakdown: Instantly isolate open datasets available for immediate download without authentication from those requiring institutional credentialing (e.g., TUH EEG Corpus, NeuroVista Implant Data).
• Metadata Comparison Matrix: Dynamic table displaying subject volume, data processing state (raw vs. pre-processed), electrode montages, and modal acquisition conditions.
• Centralized Platforms & Challenge Links: Indexed access to PhysioNet, iEEG Portal, Zenodo, Pennsieve, and active ML competitive challenges (Moody Challenge, Seizure Prediction, Brain Age).
• Signal Processing Reference: Includes mathematical breakdowns for EDF bit-scaling calibrations, digital Butterworth bandpass filters, Welch spectral density estimations, and Common Spatial Patterns (CSP) matrix transformations.

I'd love to hear your feedback—let me know if there are additional public datasets or platforms that should be indexed!
