New FM-fMRI Model Synthesizes Task fMRI from Rest Data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed FM-fMRI, a novel flow-matching model designed to synthesize task-based fMRI time series from resting-state fMRI data. This method conditions the synthesis on specific task events, enabling the generation of realistic neural dynamics. Evaluations on public and internal datasets show FM-fMRI outperforms existing methods like conditional diffusion, GANs, and VAEs in spectral and connectivity consistency. The model's utility is further demonstrated by its ability to augment limited clinical data, improving downstream diagnostic classification for autism. AI

IMPACT This model could enable more efficient and scalable fMRI studies, potentially accelerating research in neuroscience and clinical diagnostics by synthesizing task-specific data from readily available resting-state scans.

    FM-fMRI: Event Conditioned Flow Matching for Rest-to-Task fMRI Time-Series Synthesis

    arXiv:2605.26423v1 Announce Type: new Abstract: Task-based fMRI provides a direct readout of task-evoked neural dynamics, but it is expensive and difficult to acquire at scale, motivating rest-to-task synthesis from widely available resting-state fMRI (rsfMRI). We propose FM-fMRI…
