    Learning brain dynamics across distinct scaling regimes reveals psychiatric signatures

    Communications Biology. 2026 · Journal

    DOIPaper
    Abstract

    MBBN models fMRI BOLD dynamics across distinct statistical scaling regimes and evaluates predictive representations in UK Biobank, ABCD, and ABIDE. Performance varies by task and cohort; the reported prediction and model-attribution results do not establish causal mechanisms or clinical diagnostic validity.

    DIVER-0: A Fully Channel Equivariant EEG Foundation Model

    ICML 2025 Workshop on Generative AI and Biology (Spotlight). 2025 · Workshop · ICML 2025 Workshop Spotlight

    Paper
    Abstract

    Electroencephalography (EEG) is a non-invasive technique widely used in brain-computer interfaces and clinical applications, yet existing EEG foundation models face limitations in modeling spatio-temporal brain dynamics and lack channel permutation equivariance, preventing robust generalization across diverse electrode configurations. To address these challenges, we propose DIVER-0, a novel EEG foundation model that demonstrates how full spatio-temporal attention—rather than segregated spatial or temporal processing—achieves superior performance when properly designed with Rotary Position Embedding (RoPE) for temporal relationships and binary attention biases for channel differentiation. We also introduce Sliding Temporal Conditional Positional Encoding (STCPE), which improves upon existing conditional positional encoding approaches by maintaining both temporal translation equivariance and channel permutation equivariance, enabling robust adaptation to arbitrary electrode configurations unseen during pretraining. Experimental results demonstrate that DIVER-0 achieves competitive performance with only 10% of pretraining data while maintaining consistent results across all channel permutation conditions, validating its effectiveness for cross-dataset generalization and establishing key design principles for handling the inherent heterogeneity of neural recording setups.

    Polygenic scores for psychiatric traits mediate the impact of multigenerational history of depression on offspring psychopathology

    Molecular Psychiatry. 2025 · Journal · Molecular Psychiatry 2025

    DOIPaper
    Abstract

    Using cross-sectional ABCD data from 8,111 children, this study found that a depression polygenic score was associated with both multigenerational depression history and offspring psychopathology and statistically mediated 1.39–5.87% of their observed association. The analysis does not establish a causal transmission mechanism.

    NeuroMamba: A State-Space Foundation Model for Functional MRI

    PaperCode
    Abstract

    Foundation models for whole-brain fMRI analysis are dominated by two competing paradigms: Region-of-Interest (ROI) approaches that discard fine-grained spatial information, and hierarchical models with Transformer or Mamba backbones that retain it. However, the rigid, grid-based architecture of hierarchical models imposes critical limitations. They are forced to process vast, uninformative non-brain background regions (up to 60% of the data), creating significant computational inefficiency, and struggle with inter-subject anatomical variation. To overcome these challenges, we introduce NeuroMamba, a foundation model that enables direct sequence modeling of 4D whole-brain fMRI. NeuroMamba leverages Mamba backbone trained with an autoregressive objective given small spatiotemporal patches. Our approach facilitates the adaptive removal of nuisance background signals—a core inefficiency bottleneck for prior grid-based methods. To address anatomical variability, the model incorporates explicit frequency-based positional encodings, enhancing robustness across subjects. While direct sequence modeling is computationally demanding, the linear-time efficiency of Mamba, coupled with adaptive background suppression, makes whole-brain pre-training tractable. We demonstrate the first successful autoregressive pre-training on full-resolution fMRI, achieving state-of-the-art accuracy for sex classification and establishing a scalable paradigm for neuroimaging analysis.
