PLOS Comput. Biol.: The multiscale self-similarity of the weighted human brain connectome
https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1012848

4️⃣ Why is this important?: first, our findings highlight the relevance of weak connections in brain architecture, and second, the observed symmetry may reflect deeper principles of network organization, possibly linked to criticality.

3️⃣ A model to rule them all 💍🏔️: the WS1 model, based on hyperbolic geometry, explains the simultaneous occurrence of both weak and strong links. We apply a geometric renormalization technique based on the model to the highest-resolution scale and successfully reproduce the experimental results.

2️⃣ Weak links play a key role: the brain isn’t just about strong connections. Weak links - often disregarded - are crucial for bridging different communities, and their organization is consistent across scales.

1️⃣ The weighted structure of the brain is self-similar: the properties of the connection weights in the brain remain consistent when examining different parcellation resolutions.

Our work on self-similarity in the brain’s weighted structural connectivity has just been published in PLOS Computational Biology!🔗 journals.plos.org/ploscompbiol...
In short: no matter the scale we examine, the brain’s connection weights follow the same patterns! Let’s dive in…🧵👇🏻

We are excited to announce the 2nd edition of “Network Geometry: Theory and Applications" Satellite at @netsciconf.bsky.social .
Join us in Maastricht on June 3!
