Excited to see this Version Of Record of my work out in @elife.bsky.social!

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 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.

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.

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

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'.
