Can human adapt their path integration system for navigating on a sphere (non-Euclidean geometry)? We found a strong Euclidean bias. Multiple local planar maps can be used to solve a complex task. doi.org/10.1177/095679762412…

Excited to finally share the preprint of the major study of my PhD! 🥳 With @rasmusbruckner, @HeidrunSchultz and @rg_benoit , we investigated whether we can learn from imagined experiences much the same way that we learn from actual experiences. 1/5 biorxiv.org/content/10.1101/…

Learning from imagined experiences via an endogenous prediction error

Experiences shape preferences. This is particularly the case when they deviate from our expectations and thus elicit prediction errors. Here we show that prediction errors do not only occur in...

One of my PhD projects is online! We show that category prototypes correspond to interpolated states in a cognitive map that guide cortical pattern completion during category-based decisions. w/ Mirko Thalmann, @cpilab, @doellerlab, @ThevesStephanie biorxiv.org/content/10.1101/…

The hippocampus supports interpolation into new states during category abstraction

The hippocampus forms concepts by integrating multi-feature relations into a unified representation. A common yet unconfirmed assumption is that such cognitive maps afford interpolations to never-e...

There has been a lot of progress in our understanding of how the brain organises relationships in cognitive maps. But how is this knowledge used when guiding novel choice? Work with @TankredSaanum, @cpilab, @nico_schuck & @doellerlab now in @NatureNeuro rdcu.be/c83tL

Excited about our new preprint! biorxiv.org/content/10.1101/… Here, we investigate how multiple hippocampal cognitive maps are used for generalization, and the role the orbitofrontal cortex plays in updating hippocampal world models competing for behavioral control.

Hippocampal spatio-temporal cognitive maps adaptively guide reward generalization

The brain forms cognitive maps of relational knowledge, an organizing principle thought to underlie our ability to generalize and make inferences. However, how can a relevant map be selected in...
