🚀 How can we identify the brain regions that truly drive neural dynamics?
New results from the NERV Lab show that complex brain networks can be efficiently controlled through a surprisingly small set of dimensions 🔍🧠

For today's Methods Primer we will have @fdevicofallani.bsky.social talking about Duality in Complex Networks, discussing unappreciated topological properties of interconnected systems, and how those properties can be used across fields, from systems biology to neuroscience.

🚀 How does timing shape our connection with machines?

Imagining a movement just after a robot acts boosts brain decoding & the feeling of control 🧠🤖

Node-layer duality in networked systems - Nature Communications Various real-world networks in social science, technology, and biology, can be presented as multilayer structures. To better understand their properties and function, the authors propose a concept of ...

Layers, nodes… or both? 🌐

🧠 We explored node–layer duality, a framework revealing how multilayer networks can be understood from two complementary views.

Neuronal avalanches as a predictive biomarker for guiding tailored BCI training programs

A great work led by Camilla Mannino w/ @pierpasorre.bsky.social & @neurodynamicslab.bsky.social! @nerv-lab.bsky.social @institutducerveau.bsky.social 🧵

#graphtheory We demonstrate that for geometric random graphs the edge-crossing scales with the square of the number of connections (Supplementary Text 4).

#computationalgeometry We establish analytical relations between the number of connections in a spatial network and their total length (Supplementary Text 1).

#neuroscience Reflecting biological resource constraints, we show that progressive-cost models more accurately capture the key properties of brain networks (Fig 5).

#networkscience We introduce a model based on the concept of progressive cost, where adding a new link becomes increasingly expensive as the network becomes denser (Fig 4).

So many broad insights and implications on :

#dataviz We provide an unbiased criterion to filter complex networks that is compliant with common human perception (Fig 1-3)

Left or right - which one is more connected?

Most say left, but here’s the twist: both have the same number of connections!

Why does one looks more connected? It’s all about #spatiality – how links occupy space.

Dive into our latest @pnasnexus.org t.ly/JzRsc

A needed review on the topic!
May I suggest that the first work using functional brain connectivity for person identification is 2014 and not 2015.
I m sure expliciting this would make such a great service to the community.
