Complex behaviour relies on the coordination of distributed neural processes, enabled by information transfer between brain regions. Despite progress in time-resolved and directed connectivity analysis, how information actually flows in the brain remains unclear. Here, we use a novel decomposition of information transfer based on Partial Information Decomposition (PID) to analyse spontaneous BOLD fMRI dynamics. We find that transfer is dominated by temporally and informationally integrated, synergistic interactions. These findings offer a fine-grained and interpretable approach to brain dynamics, opening new potential links to cognition.
