A swap-adversarial framework for domain generalization in pre- and post-stimulation Parkinsonian state classification

The paper introduces a swap‑adversarial framework designed to address inter‑subject variability and the high‑dimensional low‑sample‑size challenge in electrocorticography (ECoG) data. It combines robust preprocessing, an inter‑subject balanced channel swap (ISBCS) for cross‑subject augmentation, and domain‑adversarial learning (DAL) to suppress subject‑specific bias, enabling robust domain generalization across both ECoG and EEG‑based brain‑computer interface datasets. The authors also present a new reproducible ECoG benchmark derived from long‑term recordings of 6‑hydroxydopamine‑induced rat models, and demonstrate the framework’s superior performance in cross‑subject, cross‑session, and cross‑dataset experiments.

LEAD: An EEG Foundation Model for Alzheimer's Disease Detection

LEAD is a gated temporal‑spatial Transformer foundation model designed for EEG‑based Alzheimer's disease detection. It was trained on the world’s largest EEG‑AD corpus of 2,238 subjects and uses a subject‑regularized strategy and medical contrastive learning across 13 datasets. LEAD outperforms existing methods on five downstream AD datasets, achieving the best average ranking across 20 evaluations.

One Model for All: Universal Pre-training for EEG based Emotion Recognition across Heterogeneous Datasets and Paradigms

The paper introduces ‘One Model for All’, a universal pre‑training framework that tackles EEG‑based emotion recognition across diverse datasets and paradigms. It decouples learning into a univariate self‑supervised contrastive pre‑training stage using a Unified Channel Schema, followed by a multivariate fine‑tuning stage that employs an Adaptive Resampling Transformer and a Graph Attention Network to model spatio‑temporal dependencies. Experiments demonstrate state‑of‑the‑art performance on within‑subject benchmarks (SEED 99.27%, DEAP 93.69%, DREAMER 93.93%) and superior cross‑dataset transfer, with ablation studies highlighting the critical role of the GAT module.

Brain4FMs: A Benchmark of Foundation Models for Electrical Brain Signal

Brain4FMs is a unified benchmark for evaluating brain foundation models (BFMs) on both scalp EEG and intracranial EEG (iEEG). It incorporates 17 representative models and 21 public datasets spanning clinical diagnosis, sleep staging, communication, and affective computing, and offers dataset-aware preprocessing, cross‑subject evaluation, and standardized downstream workflows. The benchmark highlights that no single BFM consistently outperforms others across all tasks, modalities, and adaptation protocols, prompting further exploratory analyses of model‑specific spatial, spectral, and discrete representations.

BrainWideBench: Benchmarking large-scale pretraining and across-animal transfer in multi-region neural recordings

BrainWideBench is a benchmark that evaluates across‑animal transfer on multi‑region neural recordings from 139 mice, covering 276 brain regions. It comprises three task suites—behavior decoding, neural activity prediction, and anatomical organization recovery—to test whether learned representations support diverse downstream objectives. The benchmark shows that while pretraining improves performance over single‑session baselines, current methods vary in transfer ability and none perform uniformly well across all suites, highlighting the challenge of developing general‑purpose neural representations.
