📢 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.

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

We will explore how the PFC represents structured relationships across species and how this supports flexible behavior.

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!

Transitions in dynamical regime and neural mode during perceptual decisions - Nature Simultaneous recordings were made of hundreds of neurons in the rat frontal cortex and striatum, showing that decision commitment involves a rapid, coordinated transition in dynamical regime and neura...

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.

Congrats Roxana!

Constructing future behavior in the hippocampal formation through composition and replay - Nature Neuroscience A model of compositional state spaces in the hippocampus shows latent learning and rapid generalization. Bakermans et al. show that this model predicts the emergence of place responses in replay.

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

Individual variability of neural computations underlying flexible decisions - Nature Behavioural experiments to study decision-making in response to context-dependent accumulation of evidence provide testable models that are consistent with the heterogeneity in neural signatures among...

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.

BAMB! Course philosophy Our goal is​ to teach advanced techniques in model-based analysis of behavior (humans and other animals) to cognitive and computational neuroscientists at PhD and early career levels...

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

Episodic and associative memory from spatial scaffolds in the hippocampus - Nature A neocortical–entorhinal–hippocampal network model based on grid cell states recapitulates experimental results and reconciles the spatial, associative and episodic memory roles of the hippocampus.

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!
