🧠Researchers demonstrate that Large Language Models and human brain activity share a common valence (emotional) axis, with LLMs trained on emotion-evocative sentences producing representations that align with EEG patterns across 123 subjects. However, directly supervising neural networks to match this axis paradoxically degrades performance, leading to a discovery called the 'saturation regularity' that suggests optimal brain decoding requires ensemble methods leveraging residual diversity rather than additional constraint-based training.

🧠Researchers benchmarked five positional encoding strategies for transformer-based EEG foundation models, finding that no single approach universally outperforms across different brain-computer interface tasks. Spherical Positional Encoding excels at motor imagery classification while Asymmetric Conditional Positional Encoding shows more consistent cross-task performance, suggesting optimal encoding strategies are task-dependent rather than universally applicable.

🧠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.
