Thrilled to see our paper published! I’m deeply grateful to the amazing @ggirardeau.bsky.social for trusting me to develop and carry it out. Many thanks as well to @azulsilva.bsky.social , @belalima-paiva.bsky.social and Eleonore for driving this work forward together. www.nature.com/articles/s41...

🧠 Looking forward to Mark Brandon’s visit ! His work on Head Direction coding changed how we think of the neural compass: Network gain maintains a memory trace of previous experience. 🗓️ Join us for his seminar on April 3rd at 11h30 📍45 rue des Saints-Pères, Paris

Hi BlueSky — I’m bringing over an old SciTwitter thread series exploring how beautifully the vestibular system works from a systems and computational neuroscience perspective. Chapter 1 coming shortly! I’ll keep all chapters threaded below.

'The postsubiculum as a head-direction cortex' by Adrian Duszkiewicz, Desdemona Fricker, Andrea Burgalossi & Adrien Peyrache @adrian-du.bsky.social @desdemonafricker.bsky.social @apeyrache.bsky.social www.cell.com/trends/neuro...

New paper alert! 🚨 We found that the brain's compass is remarkably stable at two scales 1️⃣ the system maintains its internal organization for weeks 2️⃣ It "remembers" its orientation for weeks, even after a single visit This may be key to how the brain aligns its other maps. Paper: rdcu.be/e3waP

La @semaineducerveau.bsky.social arrive bientôt au SPPIN ! Nous avons le plaisir d’accueillir une conférence suivie d’une visite du laboratoire par @uligraupner.bsky.social dédié aux approches optogénétiques pour comprendre les circuits neuronaux et le comportement.

We had a lot of fun doing these experiments! Theta sweeps in MEC and internal direction signals in parasubiculum track moving objects during pursuit and reverse during backward movement. Simultaneously recorded HD cells in other areas remain locked to head direction across behaviors:

If you are a PhD student or post-doc who wants to learn everything about #electrophysiology or #imaging, consider registering to the Paris Spring school in optical imaging and electrophysiology, that will take place in the center of Paris 11-23 May 2026. Application deadline Feb 2nd parisneuro.ovh

Active locomotion predictively rescues head direction attractor dynamics in head-fixed mice https://www.biorxiv.org/content/10.64898/2026.01.12.698940v1

Fantastic work!

I’m very happy to share the latest from my lab published in @Nature Hippocampal neurons that initially encode reward shift their tuning over the course of days to precede or predict reward. Full text here: rdcu.be/eY5nh

1/6: New publication from the lab: “Plastic landmark anchoring in zebrafish compass neurons” by Ryosuke Tanaka (@ryosuketanaka.bsky.social) and Ruben is available here: rdcu.be/eX1L4

Coincidence of thalamic HD signal and retrosplenial visual input is detected in the Presubiculum! 🎯 This may be the neuronal basis for landmark anchoring of the HD signal. Pleased to announce the VOR is now available elifesciences.org/articles/92443 Congrats first author Louis Richevaux 🙌

1/n: A new collaborative preprint from the lab to start the year: "A multi-ring shifter network computes head direction in zebrafish" together with Siyuan Mei, Martin Stemmler and Andreas Herz from the LMU, Munich.

No GPS in the head? Path integration by entorhinal grid cells without the grid pattern. Interesting paper from Heidelberg. www.nature.com/articles/s41...

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...

Really excited to share this Opinion piece we've been working on with fellow head-direction cell geeks @apeyrache.bsky.social @desdemonafricker.bsky.social and (bsky-less?) Andrea Burgalossi! While head-direction cells pop up in many cortical regions, we think that one of them is quite unique (1/8)

🚨new paper: the head-direction circuit as a model of primary thalamocortical system. Check this out 👇 kudos to @adrian-du.bsky.social for the huge amount of work put into this opinion piece, starting with the beautiful figures comparing the different thalamocortical systems 🤩

Dear #ParisNeuroscience community, here is the schedule of the upcoming 'Neural Networking Night' season !

2/6 Recording in decision-making regions from many neurons at once revealed the neurons' collective evolution as decisions were made Each decision had two phases: first, neural state was sensitive to sensory inputs; then, trajectories in neural state space turned and became insensitive to inputs.

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

🚨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...

*New preprint from the lab* – “Granularity of thalamic head direction cells” doi.org/10.1101/2025... 🧠📈 🧪 1/11

Happy to share our new paper with Mathilde Nordlund and Julie Koenig out @currentbiology.bsky.social. We used virtual reality in mice to study hippocampal distance coding. Our results suggest a primary contribution of grid cells to distance over cue-dependent place cell coding. shorturl.at/63yFo

Thrilled to share that our work is now published in Science! ✨ We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭 www.science.org/doi/10.1126/... 🧵1/

And the Valero / Buzsaki paper: www.science.org/doi/10.1126/...

Two flagship papers from the International Brain Laboratory, now out in ‪@Nature.com‬: 🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0 🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +

The main project from my PhD, in collaboration with Manuela Allegra and @schlab.bsky.social is now available as a preprint! We wondered how the hippocampus and the visual cortex may differ in the way they refine sensory inputs into internal representations

1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex: www.biorxiv.org/content/10.1... I personally am a big fan of the idea that cortical regions (allo and neo) are doing sequence prediction. But... 🧠📈 🧪

New work! Learning is assumed to involve synaptic plasticity, but which specific synapses change to enable higher order cognitive functions? We actually find that cognitive flexibility involves potentiation of long-range GABAergic synapses from prefrontal PV neurons: www.biorxiv.org/content/10.1...

Our study is out in Nature! Using wireless Neuropixels we recorded hippocampal activity in freely flying bats and uncovered replay and theta(less) sweeps, revealing striking differences from classic rodent models. 👉 www.nature.com/articles/s41...

Our new paper out now in Science explores how neural activity in the lateral entorhinal cortex (LEC) *drifts* over time - and *jumps* at key boundaries - to help organize events in memory. 🔗 www.science.org/doi/10.1126/... Here's a quick summary of what we found 🧵👇

Your brain doesn’t just passively track time ⏳ - it structures it. In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2) 👉 www.science.org/doi/10.1126/...

🚶Aimlessly wandering around a city or exploring the new mall may seem unproductive, but new research led by @zh0ng0.bsky.social @marius10p.bsky.social @computingnature.bsky.social suggests it could play an important role in how our brains learn.‬‬ 🧠 🔗 www.janelia.org/news/zoning-...
