GenBrain: A Generative Foundation Model of Multimodal Brain Imaging

2026-01-21

Abstract excerpt

<title>Abstract</title> <p>Neuroimaging faces a reproducibility crisis, where studies on small, heterogeneous datasets produce unreliable brain-wide associations and AI models that fail to generalize. To address this, we introduce GenBrain, a generative foundation model pretrained on approximately 1.2 million 3D scans from over 44,000 individuals across 34 imaging modalities to learn a population prior of brain s...
