🧠 New in @pnasnexus.org!
How can we simplify complex spatial networks, like brain or air traffic, without losing structure?
@fdevicofallani.bsky.social & Thibault Rolland reveal the economical geometry behind connectivity 🕸️

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.

Imagined movement increases the segregation of brain-heart networks Understanding the mechanisms of motor imagery, the mental simulation of movement without execution, is key for the development of neurotechnologies. For instance, for detecting covert motor intent in ...

More on the link brain-heart axis and sensorimotor function, relevant for BCI research 🤖: Different bodily rhythms are coupled with cortical regions at rest. Here we show that motor imagery triggers a decoupling of cardiac dynamics with motor cortex functional connectivity 🧠🫀 doi.org/10.1101/2025...

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.

Amazing feeling when testing our nonvinvasive brain-computer interface prototype!
The opening of my hand is driven by the detection in real-time of my brain network changes!
Stay tuned for upcoming applications in stroke neurorehabilitation!
Kudos to @nerv-lab.bsky.social
