NeuroAtlas: Largest EEG Benchmark for Foundation Models

Researchers have introduced NeuroAtlas, the largest EEG benchmark to date, comprising 42 datasets and 260,000 hours of data. It covers clinical EEG applications (epilepsy, sleep medicine, brain age estimation) and brain-computer interfaces, with multiple datasets per task and bespoke clinical evaluation metrics. The benchmark evaluates EEG-specific foundation models (FMs) and generic time-series FMs. Preliminary findings indicate that EEG-specific FMs do not consistently outperform time-series FMs. The study is published on arXiv under identifier 2605.14698.
