We identify a taxonomy of redundant, synergistic, and topological metrics, with topological ones bridging the two. These metrics align with brain hierarchies, track neurochemical gradients, and outperform pairwise models in fingerprinting and behavior prediction. Paper here, led by Andrea, Simone, Davide, and Marilyn.Wed, 25 Jun 2025 00:00:00 GMTWe present the first large-scale comparison of information-theoretic and topological HOI metrics using fMRI data from the Human Connectome Project. We identify a taxonomy of redundant, synergistic, and topological metrics, with topological ones bridging the two. These metrics align with brain hierarchies, track neurochemical gradients, and outperform pairwise models in fingerprinting and behavior prediction.
