Universal Brain Dynamics Model Predicts fMRI Across 963 Subjects

Researchers developed Universal Brain Dynamics (UBD), a data-driven framework that constructs a universal space for human brain activity, validated by predicting fMRI signals across eight cognitive states and 963 subjects from the Human Connectome Project (HCP). The model achieves Pearson's r > 0.9, demonstrating high accuracy. By representing resting-state fMRI within UBD, the study reveals how infra-slow fluctuations (ISF) underpin brain activity and offers a new perspective on cognitive transitions and individual differences. The work addresses the challenge of achieving universality for brain dynamics across diverse states and subjects, leveraging spatial properties from physical wiring and temporal properties from brain function.
