Congratulations Dr. Merritt!!!
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.

The multiscale self-similarity of the weighted human brain connectome
Author summary The human brain is a complex network where anatomical connections between regions, collectively known as the connectome, have varying intensities or weights. These weights influence bra...

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.
