New preprint with @SamJung @timbrady.bsky.social and @violastoermer.bsky.social: osf.io/preprints/ps.... Here we uncover what might be driving the “meaningfulness benefit” in visual working memory. Studies show that real objects are remembered better in VWM tasks than abstract stimuli. But why? 1/

The hippocampal map has its own attentional control signal! Our new study reveals that theta #sweeps can be instantly biased towards behaviourally relevant locations. See 📹 in post 4/6 and preprint here 👉 www.biorxiv.org/content/10.6... 🧵(1/6)

YOUR PHONE CALLS TO THE SENATE ARE WORKING. KEEP CALLING. 202–224-3121 Three Democrats who previously broke with the party and voted with the GOP are now saying they will not vote for the bill. That’s enough for the bill to be unpassable right now.

In a new computational analysis of previous work, this study shows that a control-free mechanism better accounts for value-based decisions than an account that assumes top-down control invigorating the best choice. @hritz.bsky.social @ashenhav.bsky.social www.nature.com/articles/s44...

Our experiences have countless details, and it can be hard to know which matter. How can we behave effectively in the future when, right now, we don't know what we'll need? Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.

At @elife.bsky.social you can now include explainer videos with every figure. Like going to a seminar while you engage with the paper. First example here elifesciences.org/articles/106... Click the arrows next to each figure to get a video of @mathiassablemeyer.bsky.social explaining it for you!

In a new paper, I delve into these two findings and muse on when prediction might help vs. hurt memory (and discuss why this matters for models of memory and the hippocampus). This is my first solo-author paper, and I had a lot of fun putting these ideas on paper! direct.mit.edu/opmi/article...

We can use past experience to make predictions about the future. How do predictions affect our memory for the present? My own work (tinyurl.com/42kyukch) suggests that predictions compete with memory. But other recent work (tinyurl.com/2ekd4wr6) found the opposite--cooperation! What's going on here?

The National Science Foundation sign on our Eisenhower Av building is now gone. The NSF mural in the foyer is removed and torn off in sheets. We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

How do hippocampal pathways contribute to learning regularities and exceptions? To answer this, Melisa Gumus & @drmack.bsky.social use diffusion imaging to identify the endpoints of different hippocampal pathways, and then analyze functional activity within those "footprints". Super innovative!

Can reward improve memory for what came before it? 🌟 In a registered report with @duncanlabuoft.bsky.social & @megschlichting.bsky.social, we reconcile mixed findings from past studies: reward retroactively boosts associative—but not item—memory, and only in reward-sensitive individuals!

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!! This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay! elifesciences.org/articles/99931

Now you recall it, now you don’t: Working memory performance fluctuates with a theta rhythm www.cell.com/neuron/abstr... #neuroscience

Our new paper in @sfnjournals.bsky.social shows different neural systems for integrating views into places--PPA integrates views *of* a location (e.g., views of a landmark), while RSC integrates views *from* a location (e.g., views of a panorama). Work by the bluesky-less Linfeng Tony Han.

Agency reorganizes memory around relevant decisions. This was collaboration the deeply missed Sarah DuBrow and steer-headed by our grad students @lindsayrait.bsky.social and Elizabeth Horwath. p.s. the task design involves curating gift baskets. pubmed.ncbi.nlm.nih.gov/41436249/

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

The district court injunction that prevented NIH from capping indirects at 15% was upheld today on appeal! www.reuters.com/world/trump-...

What if we could tell you how well you’ll remember your next visit to your local coffee shop? ☕️ In our new Nature Human Behaviour paper, we show that the 𝗾𝘂𝗮𝗹𝗶𝘁𝘆 𝗼𝗳 𝗮 𝘀𝗽𝗮𝘁𝗶𝗮𝗹 𝗿𝗲𝗽𝗿𝗲𝘀𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 can be measured with neuroimaging – and 𝘁𝗵𝗮𝘁 𝘀𝗰𝗼𝗿𝗲 𝗽𝗿𝗲𝗱𝗶𝗰𝘁𝘀 𝗵𝗼𝘄 𝘄𝗲𝗹𝗹 𝗻𝗲𝘄 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀 𝘄𝗶𝗹𝗹 𝘀𝘁𝗶𝗰𝗸.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Sleep dependent consolidation and replay that doesn’t require the hippocampus? Very beautiful work by Marcus Stephenson-Jones’ lab on sleep driven sequential skill consolidation in the striatum. www.biorxiv.org/content/10.1...

Are humans really the only rational animals? Our NEW PAPER 🎉 out in @science.org suggests otherwise! In a large collaboration led with my joint first author @hanna-schleihauf.bsky.social, we show that “Chimpanzees rationally revise their beliefs” 🧵

How do biological agents learn for the future? Our perspective piece on the value of prospective learning in neuroscience is finally out. This is part of a long running collaboration with @kordinglab.bsky.social & Josh Vogelstein (as well as many other people) www.sciencedirect.com/science/arti...

When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was. In a new paper in 𝘗𝘴𝘺𝘤𝘩𝘰𝘭𝘰𝘨𝘪𝘤𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦, out today and led by @dillonplunkett.bsky.social, we demonstrate that this happens even when there is 𝙣𝙤 𝙢𝙤𝙩𝙞𝙤𝙣 𝙬𝙝𝙖𝙩𝙨𝙤𝙚𝙫𝙚𝙧.🧵

Another new paper from the lab: Predictive theories like the SR imply that navigators who navigate differently should have cognitive maps which differ in predictable ways. Here we show that this holds in mouse hippocampal CA1. www.sciencedirect.com/science/arti...

Investigating individual-specific topographic organization has traditionally been a resource-intensive and time-consuming process. But what if we could map visual cortex organization in thousands of brains? Here we offer the community with a toolbox that can do just that! tinyurl.com/deepretinotopy

Let's compare our world models. I find that different people seem to have rather distinct internal world models. E.g. I personally have neither visual imagination nor an inner voice, found it weird others do. Here is a quick google forms to check idea: docs.google.com/forms/d/e/1F...

Super excited to share my first preprint with Katherine Duncan and Morgan Barense (@barense.bsky.social) -- "Memory strength at reactivation, not memory age, governs prediction error driven updating of naturalistic event memory"! 🧠🎉https://osf.io/preprints/psyarxiv/q9rkn_v1

How do changes in context influence how we organize our memories in time? Faster contextual changes are associated with faster drift in hippocampal activity and reduced temporal clustering in recalled memories. Elegant work led by @lindsayrait.bsky.social! www.jneurosci.org/content/45/4...

We used a brain "pinging" again and found that distractor suppression is reactive rather than proactive, meaning attention is first drawn to the distractor before being suppressed.

Do people remember where things are relative to their body (e.g. my left side) or relative to the environment (the North/uphill side)? The answer is both at once, according to my new paper now out in Psychological Science! 🧵 journals.sagepub.com/doi/10.1177/...

Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
