Really excited to be part of this amazing work! Huge congrats @danielgb_87 and company. Check out our new paper on cross species functional brain dynamics :)

Ever wondered if the *dynamic* organization of brain networks is conserved across mammals? We too!

Our latest work @NatureComm details what we found by comparing fMRI patterns in humans👨macaques 🐒 and mice🐁

[Daniel Gutierrez-Barragan @danielgb_87]

We often hear humans and macaques share 93% of the genome, and mice and humans 85%, and that we are more similar to flies than we think! But what about the brain? What are the dynamic rules that govern large-scale brain network dynamics?. 1/n

@Gozzi_Ale @chiarapepe95 @mariani_jc Exciting work! Looking forward to seeing you at the session :)

[Alessandro Gozzi @Gozzi_Ale]

5⃣ In summary, our results show that the dynamic organization of fMRI networks in the mammalian brain is evolutionarily conserved!
Kudos & congrats to mighty @danielgb_87, super⭐️ coauthors @TingsterX, @benediktramirez #stefano_panzeri & many thanks to @ERC_Research for funding!

[Alessandro Gozzi @Gozzi_Ale]

4⃣ Finally, we found that C-Mode occurrence rates "explain" many features of the steady-state organization of the fMRI connectome, including the organization and ranking of fMRI connectivity gradients

[Alessandro Gozzi @Gozzi_Ale]

3⃣ In all species, C-modes exhibit comparable coupled oscillator dynamics dynamics, and are phase locked to fMRI global signal cycles

[Alessandro Gozzi @Gozzi_Ale]

2⃣ Using this approach, we found that fMRI network dynamics in humans, awake macaques and mice is characterized by a transition between 4 dominant, neuroanatomically-homologous C-modes

[Alessandro Gozzi @Gozzi_Ale]

1⃣ Here, we propose a (very) simple formalism where spatially-opposing coactivation patterns (CAPs) are coalesced into spatiotemporal coactivation Modes (C-Modes).

The resulting dimensionality reduction was key to our ability to compare the fMRI dynamics across species!
