Our next paper on comparing dynamical systems (with special interest to artificial and biological neural networks) is out!! Joint work with @annhuang42.bsky.social , as well as @satpreetsingh.bsky.social , @leokoz8.bsky.social , Ila Fiete, and @kanakarajanphd.bsky.social : arxiv.org/pdf/2510.25943

1/ Hello Drosophila-philists and braino-maniacs! 👋🪰🧠🧪 The Caron lab has a new preprint, and it is about 🥁🥁🥁 democracy! Neuro-democracy, to be precise. So: drop EVERYTHING and listen up — a 🧶! www.biorxiv.org/content/10.1...

For obvious reasons, I've become fascinated with retrotransposons. So we ( @alexwhiteley.bsky.social and I) wrote an article now out in Neuron @cellpress.bsky.social on how we think retrotransposons influence brain function and health! kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...

With the help of AI, Princeton’s @thomas-zhihao-luo.bsky.social and @carlosbrody.bsky.social can now pinpoint the exact moment a rat makes up its mind — just by reading its brain activity 🧠🐀 pni.princeton.edu/news/2025/wh...

🛑 Attention researchers who train freely-moving rodents! Jess Breda and I developed a protocol for training center-port nose fixation 61% faster than a previous curriculum while keeping violation rates low. Preprint here: www.biorxiv.org/content/10.1...

Thank you @nancyrmack.bsky.social and @princetonneuro.bsky.social for a great explainer about our paper! pni.princeton.edu/news/2025/wh...

Friday’s AIND JC lead by Shawn Olsen and I on the Brody lab preprint ran 90+ min, unusual. Nice paper, spirited discussion. Make a clear argument that to grasp behavior we need multiregional, multi-neuron, simultaneous single-trial data. Below quotes from the paper. www.biorxiv.org/content/10.1...

What happens in your brain when you make up your mind? Postdoc (soon faculty at U. of Utah) @thomas-zhihao-luo.bsky.social and ex-grad student (now Shanahan Fellow at Allen Institute) @timkimd.bsky.social have some answers in this new paper out in Nature! www.nature.com/articles/s41... 🧵 1/6

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

Out today in @nature.com: we show that individual neurons have diverse tuning to a decision variable computed by the entire population, revealing a unifying geometric principle for the encoding of sensory and dynamic cognitive variables. www.nature.com/articles/s41...

Our paper on NHP neuropixels is finally out in Nat Neuro! These probes have already been transformative and will usher in a new era of primate neuroscience. I am extremely proud to have played a very small role in this project. I can't wait to see what our community discovers. tinyurl.com/54u3hrj8

🚀 We are excited to share that bombcell is now available in Python! 🐍 Automatically sort your units into good/MUA/noise/non-somatic using quality metrics and interpretable & adjustable classification thresholds. pip install and play around with our toy dataset: 🔗 github.com/Julie-Fabre/...

My latest Aronov lab paper is now published @Nature! When a chickadee looks at a distant location, the same place cells activate as if it were actually there 👁️ The hippocampus encodes where the bird is looking, AND what it expects to see next -- enabling spatial reasoning from afar bit.ly/3HvWSum

Delighted that the first paper from our Cy2 JWST program was published today, reporting the discovery of molecular hydrogen in the 3% Solar metallicity galaxy Leo P. This was a very fun project with @karinsandstrom.bsky.social strom.bsky.social and fabulous co-authors! www.nature.com/articles/s41...

Tired of your boring old DDM? Check out recent work by grad student @ryguy.io that introduces a *state-dependent* DDM using an underlying HMM. We find mice change their speed-accuracy strategy from trial to trial! Code provided! (in Julia of course!)

we're crowd-sourcing a searchable repository of tangible benefits stemming from federally-funded research. Come enjoy the great stories; or send in an idea; or volunteer to join the team. publicusaresearchbenefits.com please share and re-share so we get more great stories in there!

Calling all science advocates!! Carlos Brody+ are creating a searchable database of tangible science benefits, and they need you. publicusaresearchbenefits.com They are asking for suggestions - from brief to lengthy. The database is state-searchable, so all 50 states. Please spread the word!

(2/3) MAKE NOISE: 1. Share your story. Post how NSF funding has impacted your research or your life. Use #WithoutNSF to raise your voice. 2. Share your story on the Federal Freeze Tracker to help lawmakers and the public understand what’s at stake: docs.google.com/forms/d/e/1F...

So impressed by this amazing new paper answering a fundamental question about the brain:

I'll be at the Philadelphia event!

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later? Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala. 📄: nature.com/articles/s41...

Secretary of State Marco Rubio said that his department has revoked the student visas of hundreds of students so far, with plans to cancel more.

Out today in PNAS! We asked how Bayesian inference is implemented in macaque prefrontal cortex www.pnas.org/doi/10.1073/...

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

I think about this a lot. Thanks @behrenstimb.bsky.social for the wonderfully 90s-vibe blog full of wisdom! users.fmrib.ox.ac.uk/~behrens/Sta...

Hi friends, If you haven't seen it already, I was part of a mess this week — about science in the United States, and about NIH research aimed at understanding things like Alzheimer's, schizophrenia, autism, and depression. 🧪 Thread with some details. 🧠📈 🧠🤖 1/10

Standing up for science here at the New Jersey State House!

Want to learn why some neuroscientists are Standing Up for Science on March 7th? ⬇️☀️ Thank you to @thetransmitter.bsky.social for the feature! #standupforscience2025

I am very proud to announce that my PhD paper finally came out in Cell! In this *very* collaborative study, we develop and release a deep-learning approach to predict neuron type identity from their electrical signature. doi.org/10.1016/j.ce... 1/16 🧵

It’s happening, New Jersey! It’s time to rally for science!

Academic workers across the country are organizing to call on our congressional representatives on Thursday, 1/30, at 3pm ET / 12pm PT to demand these restrictions be lifted immediately. There will be a training over zoom at the beginning of the event. Join us! form.jotform.com/250226137228...

The unbearable slowness of being: Humans still clock in at just 10 bits/s. Even after peer review :) Share link: authors.elsevier.com/a/1kHVa3BtfH.... ArXiv: arxiv.org/abs/2408.10234

1/ I work in #NeuroAI, a growing field of research, which many people have only the haziest conception of... As way of introduction to this research approach, I'll provide here a very short thread outlining the definition of the field I gave recently at our BRAIN NeuroAI workshop at the NIH. 🧠📈

My lab has been working on comparing neural representations for the past few years - methods like RSA, CKA, CCA, Procrustes distance We are often asked: What do these things tell us about the system's function? How do they relate to decoding? Our new paper has some answers arxiv.org/abs/2411.08197

Woo hoo! 1K new followers, welcome to 💙🦋! For science-minded folks, there are some very cool tricks 🚀… If you use any of these emojis: 👩‍🔬|👩🏻‍🔬|👩🏼‍🔬|👩🏽‍🔬|👩🏾‍🔬|👩🏿‍🔬 your post will index on a Women in STEM feed If you use 🧪 a Science feed If you use 🧠 a Neuroscience feed Go get it 🚀🧪🧠👩‍🔬💙🎊

We wrote a short review on Dopaminergic computations for perceptual decisions with Sam Liebana and Matthias Fritsche. Hope it is useful for some. www.sciencedirect.com/science/arti.... #neuroscience 🧪🧠
