A Multi-dimensional Framework for Evaluating Generalization in EEG Foundation Models

Researchers propose a multi-dimensional evaluation framework for EEG foundation models that tests performance under realistic biomedical constraints like limited labeled data and reduced sensor coverage. Analysis of models including LaBraM, CSBrain, and CBraMod reveals foundation models excel at long-context tasks but struggle with short-window Brain-Computer Interface applications and channel constraints compared to supervised alternatives.

Aperiodic and Low-Frequency Spectral Bias in Reconstruction based EEG Foundation Models

Researchers identify a fundamental weakness in EEG foundation models: reconstruction-based pretraining causes these models to heavily bias toward aperiodic signal components while neglecting high-frequency oscillatory patterns critical for brain-computer interfaces. This spectral mismatch explains why large pretrained models underperform smaller supervised alternatives in low-resource settings.

EEG-FM-Audit: A Systematic Evaluation and Analysis Pipeline for EEG Foundation Models

Researchers introduce EEG-FM-Audit, a comprehensive evaluation framework for EEG Foundation Models that reveals properly-tuned supervised baselines can match or exceed state-of-the-art FMs with significantly fewer parameters. The study demonstrates that learning paradigm effectiveness depends heavily on dataset scale and architecture, while introducing neurophysiological probing to improve model interpretability.
