Same task, different strategy ↔️ Why do identical neural network models develop separate internal approaches to solve the same problem? @annhuang42.bsky.social explores the factors driving variability in task-trained networks in our latest @kempnerinstitute.bsky.social Deeper Learning blog.

New paper for #neurips2025! AI models adjust millions of internal settings to get better at a task. But how are these adjustments determined? For decades, we've mostly figured this out through trial & error. We took a different approach...🧵 (1/6) 🔗 openreview.net/forum?id=oMi...

Celebrating the Rajan Lab’s papers at #NeurIPS2025! Stop by to chat with these talented students and postdocs 🎉

To identify the most transformative tools and technologies in the past five years, @thetransmitter.bsky.social surveyed readers and contributors and worked with a market-research firm to interview neuroscientists around the world. See what they had to say: bit.ly/3LYTNoB #StateOfNeuroscience

📍Excited to share that our paper was selected as a Spotlight at #NeurIPS2025! arxiv.org/pdf/2410.03972 It started from a question I kept running into: When do RNNs trained on the same task converge/diverge in their solutions? 🧵⬇️

Awesome work co-led by my student @annhuang42.bsky.social and @neurostrow.bsky.social on disentangling, then comparing recurrent and externally driven dynamics! Look out for more incredible work from @annhuang42.bsky.social coming up at NeurIPS 👀

Congrats to Ann Huang for an excellent presentation at last week's @kempnerinstitute.bsky.social all-hands! 👏 Ann shared exciting updates about our InputDSA tool - more to come soon. Thrilled she had the chance to present to our engaged and supportive community.

(1/8) New paper from our team! Yu Duan & Hamza Chaudhry introduce POCO, a tool for predicting brain activity at the cellular & network level during spontaneous behavior. Find out how we built POCO & how it changes neurobehavioral research 👇 arxiv.org/abs/2506.14957

Thanks for having me at @camp_course and the @iitmadras Brain Center during my visit to India this summer!🥭 It was lovely to be back home, and a pleasure to work with the young scientists there who are finding their path in computational neuroscience 🧠

Brilliant piece by @mattperich.bsky.social on neural manifolds 🌟 His ‪essay in @thetransmitter.bsky.social shows how this view changes the game in computational neuroscience, reproducing behavioral flexibility within finite neural constraints 🧠 www.thetransmitter.org/neural-dynam...

(1/7) New preprint from Rajan lab! 🧠🤖 @ryanpaulbadman1.bsky.social & Riley Simmons-Edler show–through cog sci, neuro & ethology–how an AI agent with fewer ‘neurons’ than an insect can forage, find safety & dodge predators in a virtual world. Here's what we built Preprint: arxiv.org/pdf/2506.06981

New work incoming at #RLDM2025 🤖 🐟 While we look forward to sharing our research, I'm mindful that many colleagues, including the authors of our second abstract, can't attend due to funding & travel issues. Read the extended abstracts: rldm.org/program-2025/ #neuroskyence

👋🏽 Hi Bluesky! Happy to see so many more faces here. I’m an Associate Professor at Harvard and the Kempner Institute using AI and computational models to unlock the secrets of how our brains learn and make decisions across different scales 👩🏽‍🔬🧠🤖 #neuroskyence #academicsky www.rajanlab.com

My new piece for @thetransmitter.bsky.social. Why is treating brain dysfunction so ENORMOUSLY challenging? Because it amounts to controlling a complex system. Drawing from the history of weather research, I pose the question: Can it even be done? www.thetransmitter.org/systems-neur...

With thoughts from 14 experts, including: @manlius.bsky.social, @antihebbiann.bsky.social, @pessoabrain.bsky.social, @kanakarajanphd.bsky.social, @crozell.bsky.social. Would love to hear your thoughts as well! #neuroskyence, #complexity, 🧪​

Comments appreciated! But they are comparable insofar as some of our favorite models of the brain (like RNNs) are in fact chaotic, @kanakarajanphd.bsky.social journals.aps.org/pre/abstract... That's not to say that we shouldn't be optimistic about control (Kanaka is). But it will be hard.

Tomorrow at 1pm in WCC 103 at SfN 2023 🧠🦑 I’ll share my story from engineering & physics to neuroscience, how computational models reveal novel mechanisms & make experimental predictions, and how neurocomics could help make my field more inclusive.

Tomorrow at 3pm in Hall D at SfN 2023 ✨ SfNova with Ishmail Abdus-Saboor! I’ll talk about how advances in #AI and large scale brain data will enable computational neuroscience to answer big questions about cognition – and what the Rajan lab has discovered already!

Looking forward to #SfN23 next month! I’ll be presenting in two sessions: ✨ SfNova (Sat. 11/11 @ 3pm w. Ishmail Abdus-Saboor) 🧠 Meet-the-Expert (Sun. 11/12 @ 1pm) Learn more: www.sfn.org/meetings/neu...

Absolutely thrilled to share my postdoc work in the Axel lab. We found odor-evoked representations of the intrinsic value of information in mouse orbitofrontal cortex and showed that mice desire knowledge as its own reward. Now on bioRxiv! www.biorxiv.org/content/10.1...

Of course, forgot to tag #neuroskyence 🧠🧪 with our exciting results showing information seeking in mice, from collab with @kanakarajanphd.bsky.social @cdmdc.bsky.social @ryanpaulbadman1.bsky.social and Ethan Bromberg-Martin. Reposting our fab analysis with CEBRA from @trackingactions.bsky.social
