@poetz.bsky.social just gave us an incredible talk on whale communication. He has developed a network analysis approach to study and characterize experimental data on whale birth behavior, a fundamental stepping stone for the survival of the species.🐳 #CRAB #CCS2025

In the meantime, @poetz.bsky.social will talk at CRAB satellite (sites.google.com/view/crab202...) about recent work by Project CETI (www.projectceti.org) on understanding social dynamics during a sperm whale calf birth.

Third: most intriguingly, we found that the scaffold's structure dictates its information flow. The borders of loops handle redundant information, while the connections spanning these loops exhibit high synergy. It's a beautiful metaphor: integration happens within the voids. 8/n

This balance between redundancy and synergy, woven into each person’s unique topological scaffold, may offer a new lens on individual variability, and a powerful pathway for identifying cognitive or clinical biomarkers. 9/n

First, scaffold-based fingerprints achieved near-perfect identification accuracy (~100%), outperforming FC-based methods (~90%). Even more 🤯, they remained robust across different preprocessing strategies, brain atlases, and dramatically shortened scan times. 6/n

Second, while FC fingerprints often draw from features confined to particular brain networks, scaffolds gain their power from inter-network connections. In other words, identity seems to live in how different large-scale brain systems interact 7/n

To better capture this richer structure, we use homological scaffolds. Picture incrementally building a brain network by adding connections in order of strength. As we do this, loops begin to form. The scaffold is made of all edges that participate in these mesoscale loops 4/n

We tested this approach on resting-state fMRI data from 100 unrelated individuals in the Human Connectome Project. The results were striking. 5/n

We show that the topological structure of brain connectivity—, homological scaffolds—offers a powerful and highly robust way to identify individuals based on their functional brain organization. 2/n
