Neural State Prediction: Obstructing Shortcut Learning in EEG Foundation Models

Neural State Prediction (NSP) is a latent‑predictive framework designed to curb shortcut learning in EEG foundation models. By using a target encoder updated with an exponential moving average, identity residualization, and topology‑separated context, NSP constrains both the prediction target and the available context. Trained on 2.2 million EEG segments, NSP outperforms baselines on 14 datasets in the EEG‑FM‑Bench, achieving 63.94 % macro balanced accuracy.

Virtual iEEG from Scalp EEG: Charting the Landscape of Source Imaging, Intracranial Inference and Reconstruction

The article reviews the emerging field of virtual intracranial EEG (iEEG) derived from scalp EEG recordings. It introduces a target‑centred framework that separates event inference, feature translation, and waveform reconstruction, and it evaluates evidence based on cohort independence, coverage, and validation rigor. Current research shows limited success in inferring specific intracranial events and low‑frequency activity, but it has not yet achieved reliable reconstruction of arbitrary contact‑level signals.

iMINDBench: iEEG Multi-Institution Neural Decoding Benchmark

iMINDBench is a new benchmark for intracranial electroencephalography (iEEG) neural decoding that evaluates models on fifteen tasks across three naturalistic movie‑watching datasets from multiple institutions. It standardizes preprocessing tracks and evaluation splits to enable consistent comparisons. The study shows that pretrained systems outperform baselines within their tracks, but strong spectral baselines remain competitive, and scaling up supervised data yields only modest or task‑dependent gains.
