📢 I am delighted to announce that from Oct. 1st I will join the Institute of Computer Science (@ics-cas.bsky.social), of The Czech Academy of Sciences (@czechacademy.bsky.social).

I am very much looking forward to this new chapter in my career and life, and to work with my new colleagues.

And more surprisingly, we found that subcortical structures are internally heterogeneous; some ROIs locally connected while other ROIs play central role in global communication.

In fact, we found that all subcortical structures (not only the thalamus) contribute some ROIs to the global rich-club !

And yes, there is a rich-club at the heart of the brain-wide network, but this global rich-club is dominated by subcortical ROIs.

This is rather remarkable since the subcortex only accounts for 1% of the brain's neurons. The cerebellum, instead, with 80% of neurons, doesn't host any global hub.

The brain-wide connectome is organized into a few large-scale modules, of intermixed cortical, subcortical and cerebellar ROIs.

The entire brain is organized into a modular and hierarchical architecture, resembling the one identified for cortico-cortical networks alone, but with some remarkable differences.

Our analysis opens a dual vision of the brain's organization: an anatomical and a network viewpoint

Happy to be spending a few weeks with Jaroslav Hlinka and the COBRA team, at the Inst. of Computer Science (@ics-cas.bsky.social) of the Czech Academy of Science (@czechacademy.bsky.social).

Dobrý Den!

Sometimes, when things become stagnant, life finds its own subtle ways to tell you that the time for a change is now.

R.I.P. my 21" #iMac (2013 – 2025).
It's been a hell of a computer, the best desktop I ever had. Reeaally a pitty that #Apple decided new #iMac to be 3rd class "citizens".

#eXit ✅

After some much needed updates under the hood, a butterfly finally landed on my homepage 🦋

## Yes, I know … A more recent pic should be next 🤭 … One thing at a time 🙃

Ouch! Xmas is coming, you pass by a supermarket, see this and think 🤔
“ha, remote synchronization?”

😬😳🙄😅😅

Up and ready, nr. W16, for the last poster session today, of the #BrainModes2025 in Bilbao.
(Oh, yes 🌬🌧🌊)

4) And last, but not least, training the network to overlapping stimuli lead to the emergence of hub neurons and opening the possibility of centralised hierarchy.

3) After the learning phase, the network settles into an asynchronous irregular resting-state, displaying spontaneous memory recalls. We show that these recalls are crucial for the long-term consolidation of the learned memory items.

2) … for the model to fulfill all the requirements, the presence of two classes of inhibitory plasticity is needed.

- Hebbian STDP (fback) inhibition controls for the balancing of the firing activity, while
- Anti-Hebbian STDP (fforward) inhibition mediates memory selectivity.
