New fMRI foundation model CoFlu-Brain shows strong transfer learning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed CoFlu-Brain, a new foundation model for functional magnetic resonance imaging (fMRI) data. Unlike traditional methods that use a single correlation matrix, CoFlu-Brain organizes framewise cofluctuation observations into multiple views to capture more nuanced regional interactions. The model was pretrained on data from 13,444 subjects and demonstrated strong transfer learning capabilities across various prediction tasks, including demographic, developmental, and clinical classifications, outperforming existing models.

    CoFlu-Brain: An fMRI Connectivity Foundation Model with Cofluctuation-Based Pretraining

    Functional magnetic resonance imaging (fMRI) commonly characterizes large-scale brain organization through functional connectivity (FC). However, an observed FC matrix is not a fixed brain graph but a statistical estimate determined by the finite BOLD frames used to compute it. C…
