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

#Cosyne2026 is now open for business! Show us what you got both for the main meeting & workshop proposals 🧠🥳🧠🥳🧠

Super excited to share the first cooperative foraging paradigm in freely interacting mouse pairs! Stable leader and follower roles emerge spontaneously and predict learning. Well-trained mice show stereotyped, role-specific “behavioral motifs” absent in naive animals (1/5) doi.org/10.1101/2025...

How do animals decide if they should forage for food or stay home to take care of newborn offspring? Whose needs come first? For my PhD work now out in Nature, we examined how hunger and parenting neurons interact and are reshaped postpartum in mice 🧵⬇️ www.nature.com/articles/s41...

Proposal recommended for funding! Which means we have a fresh, 3-year-funded position available for a computational postdoc interested in studying dynamics of social interactions in rats, with simultaneous Neuropixels data to follow 🐀🐀🐀 Proper job ad pending, but email me if interested!

(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

📢🚨I’m elated to share that I’ll be starting as a tenure-track 𝗔𝘀𝘀𝗶𝘀𝘁𝗮𝗻𝘁 𝗧𝗲𝗮𝗰𝗵𝗶𝗻𝗴 𝗣𝗿𝗼𝗳𝗲𝘀𝘀𝗼𝗿 👩🏻‍🏫 in the Department of Cognitive Science at UC San Diego this July! ☀️ @ucsandiego.bsky.social 1/ #ucsd #newprofessor #womeninSTEM

“Like a group of skiers descending a mountain, each [neuron] prefers a slightly different path, but all are shaped by the same slope,” says PNI's @engeltatiana.bsky.social‬ on her lab’s new ‪@nature.com‬ study revealing how the brain makes decisions. 📰: pni.princeton.edu/news/2025/al...

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...

Thrilled to announce I'll be starting my own neuro-theory lab, as an Assistant Professor at @yaleneuro.bsky.social @wutsaiyale.bsky.social this Fall! My group will study offline learning in the sleeping brain: how neural activity self-organizes during sleep and the computations it performs. 🧵

Very happy to share the latest from my postdoc‬! 10 yrs of mouse social networks + 1.25 yrs of acoustic data ➡️ insight into vocalization & sociality in a wild population of your favorite lab model 🐁 paper: bit.ly/4n93yyD data: bit.ly/4lfFBEk code: bit.ly/4kNnMwx #bioacoustics #neuroskyence 1/8

Now out in @natcomms.nature.com‬: Mice and monkeys spontaneously shift through comparable cognitive states - and it's written all over their faces! (1/7) www.nature.com/articles/s41...

The firing of neural populations is high-dim even if their subthreshold activity is low-dim! This work by @bio-emergent.bsky.social and @haydari.bsky.social shows how, with a solvable model, a data analysis technique, and data from mouse visual cortex: www.biorxiv.org/content/10.1...

How do we get more neuroscience out of our behavioral data? Excited to share new work with C.A.Baker, M.Murthy and @jpillowtime.bsky.social, where we use natural behavior data to extend predictions from neural recordings about population codes for dynamic social stimuli: tinyurl.com/2d3wwfyf

For your Sunday enjoyment, a 110-hour dataset of mice solving puzzle boxes: arxiv.org/pdf/2505.15408 I got to see some of these videos during a visit to the Sprekeler lab; a very cute task.

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!

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...

Proud to have contributed to @jiaxuanqi.bsky.social's masterpiece out @nature.com! She shows that dopamine transients track the learned quality of song during juvenile learning and that dopamine release is driven not just by VTA firing, but by a local cholinergic mechanism! (1/x)

Calling all @cosynemeeting.bsky.social attendees! @neurokim.bsky.social, Sam Lewallen and I are organizing a 🔥🔥 workshop on graph approaches to neuroscience, including graph neural networks! For info see sites.google.com/bu.edu/gnnwo...

Excited to present the latest from the lab out today in Cell www.cell.com/cell/fulltex.... See Thread! 1/8

Our latest findings on social behavior circuits is out: how does the brain responds to social isolation? Terrific work by @dingliu.bsky.social et al. uncovering a circuit with similar neural architecture as physiological needs (hunger, thirst, sleep..). Detailed thread soon. rdcu.be/ebo63

(1/11) Today I preprinted a lot of work from my postdoc with @dudman.bsky.social, which started with a question of how the nervous system balances flexibility with efficiency of learning. The thread below gives some background.... www.biorxiv.org/content/10.1...

Paper from the lab elucidating how RNNs use low dimensional circuit mechanisms to solve task. Watch this space for more interesting projects in the works 🥳 #neuroskyence

The latent circuit model identifies low-dimensional mechanisms of task execution from heterogeneous neural responses. This approach revealed a latent inhibitory mechanism for context-dependent decisions in neural network models and prefrontal cortex 🧪🧠 www.nature.com/articles/s41...

(1/30) New preprint! "Symmetries and continuous attractors in disordered neural circuits" with Larry Abbott and Haim Sompolinsky bioRxiv: www.biorxiv.org/content/10.1...

Pre-print 🧠🧪 Is mechanism modeling dead in the AI era? ML models trained to predict neural activity fail to generalize to unseen opto perturbations. But mechanism modeling can solve that. We say "perturbation testing" is the right way to evaluate mechanisms in data-constrained models 1/8

The insanity of being a fire ecologist in the epicenter of a major fire event, bags packed and ready to evacuate, watching active fire from my window, while taking media requests and explaining to the public, for the 100,000th time how climate change is largely responsible for this

New year new work from the lab! We explore whether aggression experience and observation lead to similar changes in future aggression strategy. (They do!) We perform 2-color imaging across the whole social behavior network across time and track changes www.biorxiv.org/content/10.1...

Excited to share our #NeurIPS2024 paper on deep learning models and benchmark datasets for localizing + attributing vocalizations in social interactions! Please come visit the poster on Friday 11am-1pm PST in West Ballroom A-D #5406. Paper link: www.biorxiv.org/content/10.1...

Sniffing helps animals identify smells and connect them to places and events, but noses can’t sense time or place. How do brains connect odors with internal models of the world? Our preprint suggests that the olfactory bulb participates in this connection. www.biorxiv.org/content/10.1...

Just noticed the videos from the BRAIN NeuroAI workshops are online now, in case you missed them: videocast.nih.gov/watch=55160 videocast.nih.gov/watch=55262 n4solutionsllc.com/brain-neuroa...

(1) Vision language models can explain complex charts & decode memes, but struggle with simple tasks young kids find easy - like counting objects or finding items in cluttered scenes! Our 🆒🆕 #NeurIPS2024 paper shows why: they face the same 'binding problem' that constrains human vision! 🧵👇
