New preprint from the lab on synapse development in the nascent neocortical hierarchy! Using mice that label MAGUK proteins developed by Seth Grant we find key differences in the laminar maturation of association and sensory motor cortices, including delayed, cortex-wide maturation of L1 synapses.

I’m very excited to announce that a part of my PhD thesis project is now a preprint! In this paper, we show how spontaneous activity prior to visual experience shapes neural circuits in the retina. (1/11)

Paper out in @brainbehavimm.bsky.social! Big congrats to Anne who did all the hard work for this one 👏🎉 www.sciencedirect.com/science/arti...

Postdoc position in Paris: come help develop new generation human brain computer interfaces ⚡🧠💻 Interested? Contact me if you have experience with machine learning (e.g. simulation-based inference, RL, generative/diffusion models) or dynamical systems. See below for + details and retweet 🙏

Main postdoc study out! We can redefine prefrontal cortex regions with single-unit activity! Grateful to @carlenlab.bsky.social and @weltgeischt.bsky.social who made this crazy project real. Thanks to all co-authors, collaborators, and reviewers. www.nature.com/articles/s41...

What is a 🧠 ripple? See our @cellpress.bsky.social perspective on ripple diversity and the grammar of memory replay: connecting key pieces from current work across the field. 👉🏼 www.sciencedirect.com:5037/science/arti...

Very impressive work 🔥 Both technically (longitudinal 2p in neonatal mice requires a bit of insanity 😂) and computationally (the brain grows a lot in a week!). ❤️ the open access data too!

🚨new work with the dream team @danakarca.bsky.social @loopyluppi.bsky.social @fatemehhadaeghi.bsky.social @stuartoldham.bsky.social @duncanastle.bsky.social We use game theory and show the brain is not optimally wired for communication and there’s more to its story: www.biorxiv.org/content/10.6...

Finally got the job ad—looking for 2 PhD students to start spring next year: www.gao-unit.com/join-us/ If comp neuro, ML, and AI4Neuro is your thing, or you just nerd out over brain recordings, apply! I'm at neurips. DM me here / on the conference app or email if you want to meet 🏖️🌮

Super happy to see this one out! 🥳 Thank you to @talsharf.bsky.social, TJ, Alex and all the other co-authors, it was a super fun collaboration. Hopefully this is only my first dip into organoid ephys. I am super bullish on the technology! 🚀

thank you for listening to my EEG TED talk! (the vibes from these chairs 😅). we ran a MNE-python tutorial for >100 people for a week. the program going from preprocessing to source estimation to group analysis was ambitious, but I hope seeing all the steps involved was helpful for participants. 🙂

Mood after submitting two grants in the same week.

Neuroscience projects last several years, and you are usually a bit jaded by the time you wrap it up. Not this one– spending several months on an island in the middle of nowhere, away from all the craziness of the world reminds you how beautiful the world really is. www.youtube.com/watch?v=46sv...

5 years? WTF! That's called a kid, not a brain organoid 😂😂 www.biorxiv.org/content/10.1...

This year's #BernsteinConference was a blast! So many cool discussions, so many faces I was happy to see again, so many interesting new people to meet etc. Within this, my highlight was the PhD hackathon organized with @irinapochinok.bsky.social We had a full house of super bright students! 1/2

I've been waiting some years to make this joke and now it’s real: I conned somebody into giving me a faculty job! I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math and I'm recruiting PhD students 🤗

And we are live! Excited to announce the 2025 Multi-Agent Behavior Challenge on cross-lab supervised action recognition in mice 🐁🐀🖱️ Running on Kaggle until December 15th, with a $50,000 prize pool going to the top five submissions! www.kaggle.com/competitions...

🚨New preprint alert! The thalamus has long been seen as a relay of sensory signals to cortex. But could it also generate its own structured activity? Our study explores this question in the head-direction (HD) system. Some explanation 🧵👇 1/13 www.biorxiv.org/content/10.1...

🚨 2 Postdoc openings in Neuroscience – Liège, Belgium 🚨 We are recruiting for a project on brain development & autism that includes: ⚡ Neuropixels recordings ⚡ Opto/chemo ⚡ Behavior ⚡ Neural network modeling If you know someone, tag them or RT for visibility! 🙏 www.fens.org/careers/job-...

🚨 Excited to share the latest preprint form the lab ➡️https://tinyurl.com/32d3be9f Here we tackle a long-standing chicken-or-egg 🐣🥚question in #autism and developmental neuroscience ➡️ Is excitation–inhibition (E:I) imbalance a "cause" or a "consequence" of #autism? Check out what we found! 🧵1/n

Excited to share our new preprint on the brain-wide organization of intrinsic timescales at single neuron resolution. Work w/ @roxana-zeraati.bsky.social, @intlbrainlab.bsky.social, Anna Levina, @engeltatiana.bsky.social : www.biorxiv.org/content/10.1...

Human ripples are... very slow? 🤔 Is this a well-known fact? Plot taken from the recent @nature.com paper: www.sciencedirect.com/science/arti...

I am thrilled to share that this winter I will be starting my lab in the GIGA Institute of @universitedeliege.bsky.social! The lab will study early brain development at the intersection of systems and computational neuroscience. 🌐 You can find out more on the lab website: www.chinilab.com 1/2

The state of pseudo data-sharing.

📢 2 weeks left for Abstract submission ! Join us at the 16th BSN Meeting – Oct 20, 2025 at KU Leuven 🧠 🔗 Submit now: docs.google.com/forms/d/e/1F... 📍 Deadline: August 20th, 2025 #BSN2025 #Neuroscience #CallForAbstracts

Our first project on intrinsic neural timescales (ITs) is out! 😱🥳 We developed a new method to estimate ITs from single-unit data, which generalizes and improves the current state-of-the-art approaches. Plus, why estimating ITs on trial-based data is dangerous ☠️ Read it all here below 👇

7/7 We implemented iSTTC to tackle challenges in our own sparse, developmental datasets, and it’s working beautifully. We hope it helps others working with tricky spiking data. Try it yourself github.com/iinnpp/isttc!

"people use it very differently".. this applies to so many concepts in neuroscience! We (@irinapochinok.bsky.social and Simon Musall) put together a #BernsteinConference Workshop on exactly this and @juangallego.bsky.social will be one of our speakers! @bernsteinneuro.bsky.social shorturl.at/4kV00

🧠 Opportunity for a post-doctoral position on human neurobiology, funded by the @erc.europa.eu! 🧫You want to use human pluripotent stem cell based models to understand the evolution of human cerebellar neurons and disorders, this position is for you! 🔗Apply here: emploi.cnrs.fr/Offres/CDD/U...

Our lab is recruiting a postdoc to join a project that studies the activity in the neonate brain (mouse and human !)

Great tweetprint! 👇

1/6 Why does the brain maintain such precise excitatory-inhibitory balance? Our new preprint explores a provocative idea: Small, targeted deviations from this balance may serve a purpose: to encode local error signals for learning. www.biorxiv.org/content/10.1... led by @jrbch.bsky.social

PhD fellowship to work with me and Benedetta Franceschiello on the analysis and modelling of fast sampled fMRI data! www.ugent.be/en/work/scie...
