I’m very happy to share the latest from my lab published in @Nature Hippocampal neurons that initially encode reward shift their tuning over the course of days to precede or predict reward. Full text here: rdcu.be/eY5nh

Exciting new preprint on oxytocin neural circuits for massage led by Manon Bohic in Vicky Abraira’s lab. Sasha and I were glad to contribute imaging experiments to this collaborative effort, spanning mice to humans. Vicky is a master at bringing people together. www.biorxiv.org/content/10.6...

What a breakthrough! Such a puzzle for 30 years, this is real progress! I wonder how general this mechanism of repression is for other systems where highly-selective expression is needed. www.biorxiv.org/content/10.6...

I have a colleague who essentially created a "lab grandparent" arrangement in his lab--an esteemed emeritus researcher who is an extra mentor to trainees, collaborates on research, etc. Win win.

“There are 2 possible futures for American science. One is that this proposed budget is a bump in the road & funding will stay at close to the same level. A 2nd version is where this represents a real sea change…between gov‘t and science funding. I don’t think we know what world we’re in yet”

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

We are excited to announce the 2026 GRC Neurobiology of Cognition (7/19-24) in beautiful Waterville Valley, NH! Registration/abstract submission open. Wonderful speakers/program covering cognition across scales & species, incl. AI & neuromodulation! @desrocherslab.bsky.social @erinlrich.bsky.social

Thrilled this is out, led by former PD Cameron Ogg (now with her own lab at @rhodescollege.bsky.social!). It was a driven by a desire to see, in real-time, how LC activity/NE release influences downstream targets in behaving animals. SO hard to do, but Cameron did it! www.cell.com/cell-reports...

This is just such a damned disgrace. A crime against knowledge and humanity itself.

You should be able to respond to reviewer comments with memes to liven up the peer review process.

we’ve come a long way from 20 labs! #celegans

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...

New paper alert!!...🤩 Led by @blogeman.bsky.social, we identify how cell type-specific hormonal responses in the hypothalamus tunes parenting behavior in males and females 🐭🧠🍼. Highlights in thread 👇 1/6 www.biorxiv.org/content/10.6...

This movie shows lysosomes (orange) and keratin (gray) in a cultured cell over 10 minutes.

Some good news: U.S. sunscreens might finally be able to use a key UV filter ingredient found in many popular brands made in Japan, South Korea and European countries. The last time the FDA approved a new sunscreen ingredient was 1999. @sciam.bsky.social www.scientificamerican.com/article/u-s-...

NMDA receptor ablation in medial prefrontal cortex disrupts value updating and reward history integration https://www.biorxiv.org/content/10.64898/2025.12.06.692679v1

In many brain areas, neuronal tuning is heterogeneous. But how does this diversity help behavior? We show how tuning diversity shapes representational geometry and boosts coding efficiency for perception in our new preprint: www.biorxiv.org/content/10.1... (w/ @sueyeonchung.bsky.social&Tony Movshon)

A vigorous negative finding Subsecond dopamine transients in the striatum of mice are neither required nor sufficient for specifying the vigor of ongoing forelimb movements www.nature.com/articles/s41...

Cool project led by Victor Geadah, fitting smoothly time-varying (and condition-varying) linear dynamical systems to neural activity. arxiv.org/abs/2502.18347

33 neuroscience researchers from across the world shared how their labs our funded, providing insight into the current state of funding and how that might shift. By @claudia-lopez.bsky.social #neuroskyence #StateOfNeuroscience www.thetransmitter.org/funding/whic...

0/10 Thanks for the interest in our preprint. Some takes say it negates or fully supports the “manifold hypothesis”, neither quite right. Our results show that if you only focus on the manifold capturing most of task-related variance, you could miss important dynamics that actually drive behavior.

@thetransmitter.bsky.social’s “New Lab Directory” features a list of new neuroscience labs that opened in 2024-2025, and some set to launch in 2026. Check out the list to learn about the work of more than 50 new neuroscience labs. www.thetransmitter.org/community/th... #StateOfNeuroscience

“It is not acceptable to recruit a variety of students into the laboratory, subject them to a variety of stress tests and abuses, and then keep the students who thrive under abuse and get rid of the students who aren't able to thrive in the lab. That's straight-up exploitation.” 👏👏👏

LOVED this paper from @constantinoplelab.bsky.social showing how estrogen modulates reinforcement learning in @natureportfolio.nature.com Was also stoked to write the commentary for this paper with our superstar postdoc Masa Taira. Check it out 👇 🧠🧪

'Approximately 1 in 30 trials and more than 74 000 trial participants were affected by grant funding disruptions. Affected trials disproportionately studied infectious diseases, prevention, and behavioral interventions, and were based in the Northeastern US or in other countries.'

How do VTA DA neurons sculpt downstream representations to reinforce actions? VERY excited about our new preprint (by Alex Pan Vazquez & @czimmerman.bsky.social )

The Ctr for Urban Research at @thegraduatecenter.bsky.social (led by @jomoko.bsky.social) has prepared an online map for tonight's NYC mayoral results. Link below in #thread. For now the map is blank, but it'll fill in w/unofficial returns tonight. The map will do more than show the 2025 #s. 1/n

N-gram novelty is widely used as a measure of creativity and generalization. But if LLMs produce highly n-gram novel expressions that don’t make sense or sound awkward, should they still be called creative? In a new paper, we investigate how n-gram novelty relates to creativity.

For the past 3 years, I've taught a course on Machine Learning for Climate Change to undergrads. At times, people have asked if the course lectures could be made available online. While I can't offer that, I have decided to start making "5 Minute Papers on AI for the Planet" videos. Hope its useful!

"My candy is more of a comment"

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” 🧵

Thinking what this will mean for STEM labs and departments, especially at places like UFlorida

What does mating look like when you only have a single shot at getting it right? Very excited to share our work on an almost-invisible female control, rapidly evolving mating recognition systems, and species that break the rules and take over the world. IN MOSQUITOES>

As NSF GRFP is in the news, PLEASE spread the word about the new EGFP program they have for past GRFP honorable mentions. Universities in eligible states can apply to get funding for HMs in the same amount as GRFP. My impression is that many depts don't know this exists and so don't apply.
