Excited to have Taylor's work with me and Daphna Shohamy out in Open Mind now: even at the end of an event, it's not too late to prioritize it for long-term memory!
Sometimes we know an experience is important in the moment. Other times, its importance only becomes clear after the fact. Do these two cases have different consequences for memory? In our new paper we found that both kinds of prioritization impact memory in different ways! doi.org/10.1162/OPMI...
Really excited about this project! If you want to chat about repulsion and representational changes in hippocampus, come by our poster at #CCN2026 tomorrow at 9:30!
Here's where to find the Penn Computational Cognitive Neuroscience Lab at Cognitive Computational Neuroscience next week! See you in NYC!
So excited to be presenting @cogcompneuro.bsky.social tomorrow! #CCN2026 🎉 Contributed talk: Tues 14:40, Learning & Memory Poster: Wed 9:30-11:15, Poster C33 2026.ccneuro.org/poster/?id=E... With @johnmorrison.bsky.social @michaelshadlen.bsky.social Nick Turk-Browne, Miranda Ye & Zoe Haynes
So excited to be part of this event! I'm up in 2 talks 😀

This should be fun! I'll be talking about what it means for a neural network to have a world model (joint work with @raphaelmilliere.com) and presenting new evidence that the standard example, Othello-GPT, does not have one (joint work with @shauli.bsky.social among others).
with Alexa Tartaglini, @zfjoshying.bsky.social, Ellen Su, @solimlegris.bsky.social, @soniajoseph.bsky.social, Patrick Butlin, @johnmorrison.bsky.social, @thisismyhat.bsky.social, @jennhu.bsky.social, Ilker Yildirim, @brendenlake.bsky.social, Niko Kriegeskorte
My reply to @liadmudrik.bsky.social et al.'s proposal that we should reengineer @neddo.bsky.social's famous phenomenal/access distinction.

Final paper from @hannahtarder-stoll.bsky.social's PhD! Extending her prev work by showing how two hippocampal sequences are linked together. Part of an issue on hipp predictions edited by @mariamaly.bsky.social @barense.bsky.social @peterkok.bsky.social royalsocietypublishing.org/rstb/issue/3...

How do we update our predictions when our environment changes? The hippocampus rapidly integrates previously distinct sequences to support updated predictions. New work w/ @hannahtarder-stoll.bsky.social & @chrisbaldassano.bsky.social – part of the theme issue on hippocampal predictions!
Do LLMs *understand* language? Do educational AI agents *understand* the material they teach (or their students)? Claims about what AI systems do or don't understand are pervasive, but assessing them requires an account of MACHINE UNDERSTANDING
Tomorrow, 10:45, talk room 2! Revisiting Iconic Memory with a New Experimental Paradigm @vssmtg.bsky.social #VSS2026
Arrived @ #VSS2026 @vssmtg.bsky.social 😎🌴 If you're here - come check out my talk on Monday! Revisiting Iconic Memory with a New Experimental Paradigm Room 2 May 18th, 10:45 (1st talk) Super fun collaboration with @johnmorrison.bsky.social & my 1st study from @michaelshadlen.bsky.social lab 🤩
This talk will be 🔥. It should be of special interest to philosophers because of its implications for the overflow debate about consciousness. Gal won't have time to talk about those implications on Monday, but she'll be happy to talk about them after. Hope to see you there!

I have news! After 4 fabulous years at Northeastern, this July I will be moving to Duke—with tenure! It’s hard to convey how grateful I am to everyone who has made this possible: from old professors in Mexico and mentors in the US to students, colleagues, and, of course, my amazing wife and family.

Can humans & animals really use internal maps to take shortcuts? Tolman famously said yes - based largely on his Sunburst maze. Our new review & meta-analysis suggests evidence is far weaker than you might think. 🧵👇 doi.org/10.1111/ejn.... @uofgpsychneuro.bsky.social @ejneuroscience.bsky.social

5 years since our first pilot, and 25,000 participants later, I'm super happy this work with Makaela Nartker, @chazfirestone.bsky.social and Howard Egeth on inattentional blindness is now out in eLife! A little 🧵 of what we found... 1/12 elifesciences.org/articles/100...
Sensitivity to visual features in inattentional blindness
As a group, inattentionally blind participants can successfully report the location, color, and shape of stimuli they deny noticing, and exhibit a systematic bias to report not noticing.

Very happy to announce that our paper “Sensory Horizons and the Functions of Conscious Vision” is now out as a target article in BBS!! @smfleming.bsky.social and I present a new theory of the evolution and functions of visual consciousness. Article here: doi.org/10.1017/S014.... A (long) thread 🧵

Delighted to share a new preprint with @matthiasmichel.bsky.social! We combine human psychophysics and evolutionary constraints to propose a new hypothesis about the functions of conscious vision. This has been in the pipeline a long time- exciting to get it out in the world! osf.io/preprints/ps...

Nature, Neurons, Mushrooms, Biochemistry, and Consciousness (or the lack thereof). My top illustrations of 2023 summarize my current interests pretty well. Let's hope that in 2024 I can finally find the time to thread some of these into a coherent story. 🧠 #artvsartist #sciart #sciviz
I'm giving the university seminar in cognitive neuroscience on Monday the 27th at Columbia. I will suggest a definition of "representation" that could be useful to neuroscientists. There's a dinner afterward and they're asking for RSVPs. More details here: psychology.columbia.edu/events/cogni...
