Compositional representation of self, others, and gaze direction in *human* hippocampus - super cool.
arxiv.org/abs/2603.04747
The most impt change at #NIH and to US science this year is bigger than grant cancellations— it’s how the agency is governed.
For 75 years NIH has been largely independent of presidential control. That’s changed this year. New piece from me and @nataliebaviles.bsky.social in @nature.com

The sky is not falling; high-quality platforms (Prolific, Verasight, CR Connect) have low rates of apparent bots. osf.io/preprints/ps... But also not zero; vigilance is very much needed!
We show that synesthesia is sensory and automatic in nature: the pupil scales with the brightness of experienced synesthetic colors. doi.org/10.7554/eLif...
Now in its new dress @elife.bsky.social (convincing & valuable in round 1).
If anyone wants to pick up the method, happy to share & explain!
Very well-deserved, Zach! Congrats!! 🎉🎊 I’ll be excited to hear of your most outlandish post-tenure planned projects 😎
Every time you experience something new, your brain faces a decision: Should it update an existing memory or create a new one?
In our new paper in @sfnjournals.bsky.social #JNeurosci, we isolate that exact decision, moment-by-moment during learning 🧵
New this year at @cogneuronews.bsky.social 2026: All abstracts will be published in Proceedings of the Annual Meeting of the Cognitive Neuroscience Society jocnf.pubpub.org/cns2026. Functionality includes ability to append a visual abstract, like this: doi.org/10.21428/8e6...
1/ 🚨 New preprint
Key Moments Scaffold the Semantic Structure of Narratives
Using spoken recall and annotations from three naturalistic datasets with topic modeling, we ask: which parts of a narrative contribute most to its semantic structure and subsequently memory?
Preprint: osf.io/dcfvw
This conversation is so wholesome 😊 Keep it up, you’re both doing great!
So... A friend was supposed to give a PURELY SCIENTIFIC talk at NIH within the next couple of weeks and it was cancelled because of a "new process" where all speakers/talks have to be CLEARED BY A POLITICAL APPOINTEE.
Recently, van der Stigchel and colleagues posted a provocative commentary suggesting that we should be wary of bots in online behavioral data collection (🧵by @cstrauch.bsky.social here: bsky.app/profile/cstr...). But should we? Here is my response letter osf.io/preprints/ps.... 1/5
Excited to share our paper (with @jzacks.bsky.social), now out in JEP:LMC!
Event boundaries sometimes disrupt temporal order memory in list-based paradigms—but what happens in narratives with more complex structures that better resemble real life?

Way to go, Thomas! I’ve been in awe of this work since I first heard you and Katherine talk about it. Just beautiful. Congrats!!🎉
I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠

Sorry for the delay – the PsyArXiv link works now 😅
1/6 Happy to share our new paper with @grassocamille.bsky.social and @virginievanw.bsky.social: "Nested contextual change and the temporal compression of episodic memory". www.biorxiv.org/content/10.6...
📍2003 marked the year in which the retro-cue paradigm was born. Fast forward, 23 years later, we adapt this logic to long-term memory and ask how does attention shape retrieval from long-term memory? 🤔

America needs a Surgeon General who follows the science, not trending conspiracies and pseudoscience. Tell your Senator to vote against Casey Means as our nation’s doctor!
Don't you love not having access to your own work 🙄?
Just sent! Enjoy 😅
Ah yes, you're right – they changed from post-moderation to pre-moderation. Here's the preprint via Dropbox!
How do we balance external attention to the outside world and internal attention to our thoughts & memories?
We review evidence that external and internal attention can compete, unfold concurrently, or cooperate!
Loved working on this with @samversc.bsky.social & @tobiasegner.bsky.social!
New with @tobiasegner.bsky.social & @mariamaly.bsky.social! The relationship between external and internal attention is not fixed but varies between competition, concurrence, and cooperation. We shed light on the conditions that allow for each of these relationships to occur🔍

Experimental task. Trials began with variable fixation (500–1,000 ms) and placeholder (500–1,000 ms) intervals, followed by two spatial cues (100 ms) on opposite sides of the visual field to indicate the likely locations of both a subsequent near-threshold target and a salient distractor (100 ms). Cue validity was 70% for both cue types. Targets and distractors were presented after a variable delay (500–1,600 ms). Stimulus displays could include (i) both a target and a distractor, (ii) a target only, (iii) a distractor only, or (iv) neither a target nor a distractor. The number pad on a computer keyboard was used to indicate the presence of a target at the cued location, a target at a non-cued location, or no target.
Attentional resources vary rhythmically, but what about susceptibility to #distractors?@fiebelkornian.bsky.social &co show that theta & alpha phases modulate sensitivity & distractor impact, revealing rhythm-specific mechanisms shaping #attention & distractability @plosbiology.org 🧪 plos.io/4tU0vh4
Where you look next isn’t arbitrary.
In our new paper, we model human eye movements in immersive visual search as reinforcement learning under cognitive constraints. 🧵

What happens to the hippocampal “place code” when an animal is actively engaged in a task?
The answer surprised us (and might surprise you too!).
