Reposted by Giovanni PetriSam Gershman @gershbrain.bsky.social · 19/04/2026There seems to be a broad perception across psychology and neuroscience that work shouldn't be "too technical" in order to reach the broadest possible audience. While I think we should strive for accessibility, I feel that this attitude can also be self-defeating: why are we dumbing down? 78816

Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025This 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 121
Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025Third: 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 221
Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025Second, 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 121
Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025First, 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 121

Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025To 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 121
Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025Traditional approaches to brain fingerprinting typically rely on Functional Connectivity (FC), which measures pairwise correlations between brain regions. But brains don’t just operate in pairs—networks of regions interact in complex, higher-order ways that FC often misses. 3/n 121
Reposted by Giovanni PetriSimone Poetto @poetz.bsky.social · 30/06/2025We 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 131
