The final typeset version of this paper is online now! Check out the new analysis approach that Narjes developed to track changes in event structure at multiple timescales, allowing us to see how event dynamics in a film clip change with repeated viewing

How do the brain’s event representations change as we gain familiarity with an experience? Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory. Excited to share this work w/ Narjes Al-Zahli & @chrisbaldassano.bsky.social!

Many everyday experiences share a recurring structure: routines, familiar routes, rewatched films, and replayed songs. How do repeated encounters with such structure alter the brain’s representations ...

What happens when we learn a new shortcut between places we thought were unconnected? Hannah found that the hippocampus rapidly adjusts its representations of environments to join them into a connected map - excited to share this final paper from her PhD work with me and @mariamaly.bsky.social !

Is forgetting useful? This was among the deep questions about how memories are formed and used explored at Local Circuits, a symposium that brought together leading experts in biological and artificial intelligence @columbiauniversity.bsky.social zuckermaninstitute.columbia.edu/symposium-me...

MDRS is a professional society dedicated to the study of memory. Members engage in basic and clinical research into how memory works and why it fails.

I'm recruiting PhD students to join my new lab in Fall 2026! The Shared Minds Lab at @usc.edu will combine deep learning and ecological human neuroscience to better understand how we communicate our thoughts from one brain to another.

👋 Happy to see this paper published in PNAS www.pnas.org/doi/10.1073/pnas.2529176123 Asking: is curiosity a homeostatic drive, or a policy learned through reinforcement? How can we tell, and why does it matter? 🧵👇 With Jane Mok, @chrisbaldassano.bsky.social, Caroline Marvin, and Daphna Shohamy 🙏

Years ago my lab tried to brainstorm ways to separately manipulate low-level (texture/pattern) and high-level (scene/object) image properties, for studying visual representations in the brain. Thanks to imaginative work by PhD student Zall Hirschstein, we now have a stimulus set that does just that!

Columbia Psych is hiring *two* junior faculty in Cognitive Science/Neuroscience this year! If you work on cognition (broadly defined), submit your application materials as soon as possible (review starts Nov 1). If you have questions you can reach out to me by email! apply.interfolio.com/175428

Nice article from Columbia News on our new paper about neural representations of places and remembered items - including a video of the creative VR environment made by @xrmasiso.bsky.social ! news.columbia.edu/news/places-...

Our new paper out in NHB! We started this back in @ptoncompmemlab.bsky.social's lab when I was a postdoc and Rolando was a grad student, showing that stable fMRI representations of places (learned in Rolando's custom-made VR world) provide the best anchors for later item learning

Human curiosity is dynamic, however the principles governing its fluctuations remain debated. Here, we test two competing hypotheses about how past...

How do we update our predictions when our environment changes? The hippocampus rapidly integrates previously distinct sequences to support updated predictions. Proud of this work with Hannah Tarder-Stoll & @chrisbaldassano.bsky.social! www.biorxiv.org/content/10.1...

Psychology researchers used virtual reality and MRI technology to better understand how locations help us encode memories.

Memories for temporally extended sequences can be used adaptively to predict future events on multiple timescales, a function that relies on the hippocampus. For such predictions to be useful, they sh...

What drives human curiosity? Is it a need to balance stimulation — or something we learn over time? In our 🚨 new preprint, we show that learning reinforces curiosity, especially for related content. osf.io/9bw6j_v2 w/ Jane Mok, @chrisbaldassano.bsky.social , Caroline Marvin, Daphna Shohamy 🧵👇

Excited to release the SPOT grid: a new image set that factorially crosses scene-object & texture-pattern pairings. We hope these stimuli will be useful to researchers aiming to (partially) disentangle the contributions of lower- and higher-level visual features to behavior & brain activity. 1/

New study by @xrmasiso.bsky.social et al shows that spatial contexts with more reliable brain representations better support memory for future experiences within them, revealing how stable neural maps help the brain organize and recall life events.
