Global remapping of the sensory homunculus emerges early in childhood development - Nature Communications Children born without a hand show early, widespread changes in brain maps, with body parts shifting across the homunculus. Adaptive behaviours explain individual differences but cannot override this e...

We're thrilled to announce that our new research article, "Global remapping of the sensory homunculus emerges early in childhood development”, has just been published in Nature Communications (www.nature.com/articles/s41...) with @dorothycowie.bsky.social and Matej Hoffman.

Congratulation Filippo, it was a pleasure to work with you on how visual features influence (or not) the learning of a new script.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Please check out and RT this new position for an exciting collaborative project with @boninlab.bsky.social and @franckp.bsky.social on the links between human-specific mechanisms and neurodevelopmental disorders in cortical circuits.

Deux cents ans après son invention, le braille devrait être bientôt reconnu par l'Unesco. Son apprentissage et son usage, grâce à la mobilisation en particulier d'un homme. Et alors que ce système est confronté à des technologies vocales boostées par l'IA.

Super excited to share a new preprint!

We asked a simple-but-big question:

What changes in the brain when someone becomes an expert?

Using chess ♟️ + fMRI 🧠 + representational geometry & dimensionality 📈, we ask:

1️⃣ WHAT information is encoded?
2️⃣ HOW is it structured?
3️⃣ WHERE is it expressed?

Do a postdoc with us in San Francisco! A fellowship slot in vision science, clinical vision, blindness, or rehabilitation is available via a NEI T32 slot: 👇🏼

Interested in how the brain encodes numerosity across the senses or presentation formats? Check out our latest paper in @sfnjournals.bsky.social masterfully executed by @yyagpsy.bsky.social

I’ll soon(ish) post an ad for a postdoc position in my lab to study individual differences in brain plasticity following blindness or deafness, with a start date of spring/summer 2026. Feel free to email me if you’re interested.

Celebration day for the 200 years of the Braille system, the universal tactile reading system for blind.
I will speak about how the mind and brain process this crucial cultural invention.

Congratulation Filippo, it was an interesting and fun ride.

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time!

Might focused ultrasound one day replace DBS?

UK Scientists built a 256-panel focused ultrasound helmet that can precisely target deep brain regions. Using theta-burst TUS, they stimulated the LGN and found visual cortex activity with effects lasting up to 40 minutes.
