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.

Our team is recruiting postdocs interested in using calcium imaging & in vivo ephys to study how the hippocampus prefrontal cortex dynamically control context-guided defensive behaviours πŸ‡¨πŸ‡¦ rozeskelab.org @uoft.bsky.social @utsc.bsky.social

Our global study on the state of trust in scientists is now out in Nature Human Behaviour! πŸ₯³

With a team of 241 researchers, we surveyed 71,922 people in 68 countries, providing the largest dataset on trust in scientists post-pandemic πŸ‘‡πŸ§΅https://www.nature.com/articles/s41562-024-02090-5

Early-life stress induces persistent astrocyte dysfunction associated with fear generalisation Early-life stress can have lifelong consequences, enhancing stress susceptibility and resulting in behavioural and cognitive deficits. While the effects of early-life stress on neuronal function have ...

Delighted to share an update to our preprint, reviewed at @elife.bsky.social, and now sent back for re-review.
Colossal work by the team and driven home by @mathiasgua.bsky.social

A cellular basis for mapping behavioural structure - Nature Mice generalize complex task structures by using neurons in the medial frontal cortex that encode progress to task goals and embed behavioural sequences.

Out now in Nature from @behrenstimb.bsky.social and crew:

Understanding this kind of schematic pattern learning and transfer will be key, IMO, to moving towards models of what we might call "higher-order cognition" or "reasoning".

Idiosyncratic navigation determines mouse CA1 representational structure in a multicompartment environment Organisms from mice to humans rely on cognitive maps instantiated by the hippocampal formation to flexibly and efficiently navigate the world. Traditional theories of cognitive mapping posit that thes...

Super excited to share our first preprint of work from the lab! We monitor and manipulate the CA1 representation of mice exploring a multicompartment environment to contrast geometric vs. predictive theories of cognitive mapping.

TLDR: All signs point to a predictive theory!
