🚨 New preprint w/ Valerio Rubino and Peter Dayan: how do people discover and use compositional structure under constraints? osf.io/preprints/ps... A key factor is a simple heuristic that favors reuse of repeated and symmetric fragments across scales, is robust to time pressure, and sped up RTs 🧵👇

📢 PhD opportunity between France and Italy I’m recruiting an international PhD student for OPTIFLEX, a project co-supervised between Marseille and Genova on the optical control of neural circuits for action selection in mice. Details and application: schadoc.univ-amu.fr/en/projects/...

It's Cosyne time!! Here are some contributions from my lab and some of my close collaborator labs (Thomas Akam, @melgaby.bsky.social, Steve Kennerley, @sameershethmd.bsky.social )

Come join us at BAMB! to learn all about modelling behavior and what Barcelona’s beaches have to offer 🏐🏄‍♂️🏊‍♂️ Applications for 2026 are open here: www.bambschool.org

Applications for BAMB! 2026 are officially open! Join us in Barcelona (July 12–23) to master the art of behavioral modeling with our incredible faculty: @meganakpeters.bsky.social @marcelomattar.bsky.social @khamascience.bsky.social @thecharleywu.bsky.social Apply now here: www.bambschool.org

*Multi-region computations in the brain* When two regions are better than one... doi.org/10.1016/j.ne... #neuroskyence

Excited to see this Version Of Record of my work out in @elife.bsky.social! elifesciences.org/articles/106... We investigate the mental representation of geometric shapes in adults and children using fMRI and MEG. Each figure has a video of me explaining the figure: go and read it, or read below.

come check out this #SfN25 minisymposium happening today at 2pm! we will discuss recent approaches to make sense of multi-area population dynamics www.jneurosci.org/content/45/4...

Come join us at #SfN25 for the minisymposium "Cognitive Maps in the Prefrontal Cortex"! Saturday, Nov 15, 2:00-4:30pm, Room SDCC 6CF www.abstractsonline.com/pp8/#!/21171... We will explore how the PFC represents structured relationships across species and how this supports flexible behavior.

Introducing hMFC: A Bayesian hierarchical model of trial-to-trial fluctuations in decision criterion! Now out in @plos.org Comp Bio. led by Robin Vloeberghs with @anne-urai.bsky.social Scott Linderman Paper: desenderlab.com/wp-content/u... Thread ↓↓↓ #PsychSciSky #Neuroscience #Neuroskyence

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! www.biorxiv.org/content/10.1...

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

Happy to share the latest version of our work on compositional maps in hippocampus with Jo Warren, @jcrwhittington.bsky.social, @behrenstimb.bsky.social. We propose hippocampus constructs maps from cortical building blocks in replay – now with empirical support! www.nature.com/articles/s41... 1/9

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

Super excited to share this new work from my collaboration with @annduan.bsky.social. It's the most innovative project I have worked on. We explored the strategies of mice as they raced for visually cued rewards in 'the Octagon'.

BAMB! is happening again in 2025. Learn how to model your behavioural data, next to the beach in Barcelona! keynotes this year from @athenaakrami.bsky.social and Peter Dayan.

Our Barcelona-based summer school, BAMB! (bambschool.org) just opened applications! Come join us: 15-24th July, to learn how to model behavioral data using RL, Bayesian, latent variable models, RNNs, DDMs & more! #BAMB2025

1/ Super-excited to share our new work “Episodic and associative memory from spatial scaffolds in the hippocampus”, that just appeared in Nature! www.nature.com/articles/s41... Key insights and ideas 👇#tweeprint

This is the future - fitting dynamical systems models with cell type specification 🔥🔥🔥

Excited to share our NeurIPS spotlight paper that develops cell-type dynamical systems to understand the effects of neural perturbations, and roles of distinct cell classes in a neural circuit! Joint work w/ @dikshagup.bsky.social , Carlos Brody, @jpillowtime.bsky.social . (Details below)
