Our paper on olfactory evidence accumulation is now officially published with the final clean version! With @luxorboero.bsky.social, Hao Wu, @josephdzak.bsky.social, @paulmasset.bsky.social, Farhad Pashakhanloo, @siddjakes.bsky.social, @btolooshams.bsky.social & Demba Ba.

Tremendously excited to announce that I will be joining @rockefeller.edu as an Assistant Professor and Head of Lab starting in January 2027! My group will be broadly focused on theoretical neuroscience, and mathematical problems in neural computation in the large.

Our latest story is finally in preprint! 🧠✨ How does the brain solve the (hierarchical) credit assignment problem efficiently? Cell-type-specific cortical feedback holds the key, closely approximating backprop. Paper: doi.org/10.64898/202...

Cell-type-specific cortical feedback coordinates hierarchical credit assignment

Learning is thought to arise from synaptic modifications embedded in brain-wide circuits, yet how such circuits coordinate plasticity to support complex behaviour is not known. Inspired by deep learni...

New beautiful normative/theory paper from Ethan Bromberg-Martin with Josh Merel Why are we curious? What is the origin of our non instrumental seeming information preference? www.biorxiv.org/content/10.6...

Why do we want to know the future? Humans and many animals pay for information to predict uncertain rewards, even when they cannot control them. The reason for this conserved yet seemingly paradoxical...

“Specific expansion of motor cortical projections in a singing mouse” Great new work by @arkarupbanerjee.bsky.social E. Isco @cliffscience.bsky.social @xmikezheng20.bsky.social @tonyzador.bsky.social & colleagues on the neural basis of vocal dexterity, now out in @nature.com 🧪🧠

1/7 New paper accepted as ICML spotlight arxiv.org/abs/2605.03517! We unify self-supervised learning (SSL) algorithms (e.g., contrastive, VICReg, stopgrad) via latent distribution matching (LDM), which matches an induced latent distribution to an explicit latent model.

Our work on the perception of intermittent odor stimuli out in @natcomms.nature.com! Led by @luxorboero.bsky.social & former grad student Hao Wu; key contributions from @btolooshams.bsky.social, @siddjakes.bsky.social, @paulmasset.bsky.social, @josephdzak.bsky.social, Farhad Pashakhanloo, Demba Ba.

When it comes to sensory processing, cortex should not get all the credit... In olfaction, a key challenge is identifying odors regardless of concentration. Our new paper in @natneuro.nature.com shows how the olfactory bulb performs this crucial computation before signals even reach the cortex.

Delighted to share our discoveries about one of the brain's neurotransmitter systems: www.biorxiv.org/content/10.6... Together with colleagues at the @alleninstitute.org, we have learned a lot about a tiny cluster of neurons in the brainstem locus coeruleus (LC) that releases norepinephrine (NE). 1

Thrilled to share our new paper, which shows that the relative timing of cholinergic and dopamine release dynamically gates whether dopamine acts as an RPE for in vivo plasticity and reinforcement learning. www.nature.com/articles/s41...

We're thrilled to share that the Call for Workshops for this year's @rl-conference.bsky.social is now live! As Workshop co-chair (alongside the wonderful Raksha Kumaraswamy and @claireve.bsky.social) we are looking forward to seeing the proposals for workshops that we receive. LINK IN NEXT POST

New paper alert! 🚨 We found that the brain's compass is remarkably stable at two scales 1️⃣ the system maintains its internal organization for weeks 2️⃣ It "remembers" its orientation for weeks, even after a single visit This may be key to how the brain aligns its other maps. Paper: rdcu.be/e3waP

Our paper is out in @natneuro.nature.com! www.nature.com/articles/s41... We develop a geometric theory of how neural populations support generalization across many tasks. @zuckermanbrain.bsky.social @flatironinstitute.org @kempnerinstitute.bsky.social 1/14

@kordinglab.bsky.social and I ran a summer school last year to help young profs (<5 yrs) in systems/comp neuro thrive. compneurosci.com/Neuro4Pros/i... It was great! Now we want to know if you'd be interested in participating if we did this again this year? Let us know!

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

With some trepidation, I'm putting this out into the world: gershmanlab.com/textbook.html It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class. My hope is that this will be a living document, continuously improved as I get feedback.

When we learn complex tasks, we chunk them into sub-tasks that our brains orchestrate into action sequences. How we do this is not entirely understood. This work explores how to learn and internally control temporally abstracted sub-tasks in RL/AI with sequence models. arxiv.org/abs/2512.20605

Emergent temporal abstractions in autoregressive models enable hierarchical reinforcement learning

Large-scale autoregressive models pretrained on next-token prediction and finetuned with reinforcement learning (RL) have achieved unprecedented success on many problem domains. During RL, these model...

🧠 New year, new preprint! Why does motor learning involve multiple brain regions? We propose that the cortico-cerebellar system learns a "map" of actions where similar movements are nearby, while basal ganglia do RL in this simplified space. www.biorxiv.org/content/10.6...
