Brain Harmony: A Multimodal Foundation Model Unifying Morphology and Function into 1D Tokens

Zijian Dong, Li Ruilin, Joanna Su Xian Chong, Niousha Dehestani, Yinghui Teng, Yi Lin +6

NeurIPS 2025poster

We present **Brain Harmony (BrainHarmonix)**, the first multimodal brain foundation model that unifies structural morphology and functional dynamics into compact 1D token representations. The model was pretrained on two of the largest neuroimaging datasets to date, encompassing 64,594 T1-weighted s…

Brain-JEPA: Brain Dynamics Foundation Model with Gradient Positioning and Spatiotemporal Masking

Zijian Dong, Li Ruilin, Yilei Wu, Thuan Tinh Nguyen, Joanna Su Xian Chong, Fang Ji +3

NeurIPS 2024spotlight

We introduce *Brain-JEPA*, a brain dynamics foundation model with the Joint-Embedding Predictive Architecture (JEPA). This pioneering model achieves state-of-the-art performance in demographic prediction, disease diagnosis/prognosis, and trait prediction through fine-tuning. Furthermore, it excels i…
