    How do we integrate sequences of information over time? In a study led by Sherry Chien () we measured how the brains of different people align, second-by-second, when they hear the same sentence preceded by different contexts. We found a hierarchical gradient in cortex:

    Kathrin's findings are finally out: motor and premotor cortices are involved in transforming what we hear into what we say. A summary of the results (from the original preprint) is here: . A collaboration with , and Kean-Ming Tan.

    Excited to see this up on biorxiv. This was a fun collaboration. Tagging Marge too . She does have a twitter account, which she manages to use even less than I do.

    Check out our new work with , , and ! We show that hippocampal place cells remap in similar + predictable ways across rats. This challenges the standard view that place cell remapping is random. 🐀🧠🗺️ Preprint here:

    Object-oriented images cause boundary extension — but scene-oriented images cause boundary contraction. This happens even when participants are copying an image right in front of them This paper by & looks amazing!

    Cues that predict reward activate dopamine neurons but the function of this response remained unclear. This study demonstrates that inhibiting dopamine cue responses impairs second-order conditioning as predicted from TD learning theory. Elegant study!

    Interested in the relationship between schemas and the episodes that make them up? Check out our new preprint! We find that episodic retrieval relies more on schematic memory over time, even as the schemas themselves become less precisely remembered.
