Yang ICoN researchers are revealing the shared rules of balance across species. 🧠🚶‍♀️🐭🪰 Humans, mice, and flies all use the same error-correction strategy to stay upright, thanks to new work led by ICoN Center’s @nidhise.bsky.social & ICoN Fellow @antoinecomite.bsky.social.

New preprint; Shared feedback control principles across standing and walking. With Yang Geng and @jvandieen.bsky.social. Feedback welcome! www.biorxiv.org/content/10.1...

Let's compare our world models. I find that different people seem to have rather distinct internal world models. E.g. I personally have neither visual imagination nor an inner voice, found it weird others do. Here is a quick google forms to check idea: docs.google.com/forms/d/e/1F...

The best place in the world to be at the cutting edge of muscle models!

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

My research group has an open position for a postdoc! Interested in investigating the postural transition towards mammalian gait using movement simulations? We might have the right position for you! More details and application info here: www.asm.tf.fau.de/en/2025/11/1...

On a similar note, I feel like we ought to stop writing papers as flowing text and instead just have the bullet points you would have used as a prompt. I'm actually not joking.

MLMC2025 is tomorrow! For those joining remotely, here is the link for the meeting: harvard.zoom.us/j/9544921964... Reminder, the conference will start promptly at 9am PST. Please visit the website for additional information, schedule, registration, etc! motor-conference.org/openconf.php

Come to my poster at SfN on Wednesday morning! I'll present my work on how the cerebellum uses internal models to control neocortical dynamics in a non-motor learning task. I'm biased, but I think it's pretty exciting! www.abstractsonline.com/pp8/#!/21171...

India won the Women’s Cricket World Cup for the first time with a 52-run victory over South Africa on Sunday.

1/N How do neural dynamics in motor cortex interact with those in subcortical networks to flexibly control movement? I’m beyond thrilled to share our work on this problem, led by Eric Kirk @eric-kirk.bsky.social with help from Kangjia Cai! www.biorxiv.org/content/10.1...

We are excited to share our new paper that dives into how ongoing decision deliberation reflects ongoing movements: (jneurosci.org/content/45/3... A tour-de-force by the incredible Jan Calalo.

The cerebellum isn’t just about coordinating movement. It’s implicated in nearly every domain of cognition—from language to social behavior. But how exactly does the cerebellum contribute to action and cognition? 🧵 Check out our new paper w/ Rich Ivry. arxiv.org/abs/2509.09818

Stoked to see our study out in final form! Big kudos to @jonathanamichaels.bsky.social for driving this along for the past 5 years.

New Pre-Print: www.biorxiv.org/cgi/content/... We’re all familiar with having to practice a new skill to get better at it, but what really happens during practice? The answer, I propose, is reinforcement learning - specifically policy-gradient reinforcement learning. Overview 🧵 below...

Our 2024 paper showed that policy gradient RL (with performance-based memory updates) predicts long-horizon motor learning. Now, @adrianhaith.bsky.social shows that policy-gradient RL also explains learning in other shorter horizon tasks. Exciting! www.biorxiv.org/content/10.1...

Important work by @nidhise.bsky.social discovering signatures of control for stable locomotion across species. Excited to see the models applied to diverse species as part of IMSI @movementscience.bsky.social

Check out this #incredible work on #stability and #control during movement across #humans, #mice, and #flies. Congratulations @nidhise.bsky.social and @antoinecomite.bsky.social 👏🏽⭐

Excited that this work discovering cross-species signatures of stabilizing foot placement control is now out in PNAS! pnas.org/doi/10.1073/... @antoinecomite.bsky.social

Understanding behavior requires datasets that capture humans while carrying out complex tasks. The kitchen is an excellent environment for assessing human motor and cognitive function, as many complex actions are naturally exhibited in kitchens from chopping to 🧽! arxiv.org/abs/2506.01608

Last week, I had the incredible privilege of talking with the @mit.edu first-generation, low income graduating class of 2025 as the event's keynote speaker. (1/n)

The NSF Integrative Movement Sciences Institute (IMSI) is a major biology research center spanning over 20 US institutions. The Mission: To understand why we move like we do--from molecules to muscles to our environment. At our Summer Institute, we train new students in our labs--like Hannah Chow:

In Nov last year, we published a predictive theory of locomotor adaptation to novel environments, capturing learning and generalization phenomena in over ten experiments: www.nature.com/articles/s41... I'm honored to be featured on the 2025 Innovators Under 35 list for this work. ter.li/7c0jek

We test this by considering a cross-linguistic dataset of locomotion naming 🏃‍♀️💃🚶 We find that even in this challenging dynamical multi-modal domain, systems of semantic categories across languages are significantly efficient 7/n

Cogsci and AI: two different approaches as articulated by Josh Tenenbaum #cogsci2025

This is what the science machine does. No massive breakthrough. No single cure. Just lots and lots of cumulative knowledge that makes things better… www.theguardian.com/society/2025...

Ugh… there’s also what I call messianic AI, the fantasy that AI will “solve” science. Treating science like a vending machine for solitons/profit & scientists as human cogs replaceable by machinery. But Science is a living culture of critical discussion, mentorship, shared community values &methods.

100%! Universities and scientists should not cave, THE PUBLIC IS WITH US! We much FIGHT BACK against efforts to demolish US universities and US science, two things that actually make America great.

Neuroethology ftw!

Very proud of MIT for waiving tuition for any student from a family making less than $200K. abcnews.go.com/US/massachus...

Announcing a new week-long program for young computational neuroscience/ behavior professors to talk about rigorous science, mentoring, lab management, and networking in a stunning retreat setting. Do great science as a community and have fun doing so.

I've noticed that journals hold theory papers to experiment-centric standards, stifling idea generation. JEB has launched an article type for theory+modeling that will address this. A bold move and sign of thoughtful leadership -- will other journals follow? journals.biologists.com/jeb/article/...

Hello to all the new Bluesky-ers! I’m a postdoc at Harvard working to improve neural interfaces using implantable devices and neurosurgical reconstruction. I wrapped up my PhD in Robotics earlier this year, where I worked on augmenting human locomotor balance using intelligent wearable robots.

I’m giving a career talk for SfN Online this afternoon at 1pm EST. Free for members or $15. neuronline.sfn.org/scientific-r...

Persian/islamic scientists & philosophers that I grew up reading about made their breakthroughs while searching in the space between math, alchemy, poetry, philosophy, medicine. Newton mostly worked on esoteric knowledge & collected crystals. To turn the ship around, we need paradigm shifts.

Some thoughts on the value of exploratory studies in movement science. A thread. tl;dr Most studies in our field are exploratory, not confirmatory, and that’s okay. However, we could all benefit from rethinking how we do, report, and interpret this exploratory work.

How do animals walk stably in the presence of intrinsic noise or external perturbations? biorxiv.org/content/10.1... We lack a unified answer to this question across species. In this preprint, we find that legged species use a shared strategy for stable locomotion: foot placement control! (1/6)

The addbiomechanics.org tool is now citable! Article: journals.plos.org/plosone/arti... Automatic model scaling for more accurate inverse kinematics and dynamics, in minutes. Fun collab led by Karen Liu, kicked off by a survey here :-) Much improved in past few months. Give it a try!

I'm happy that my debut post is to announce that our long-awaited Gait Signatures paper is finally out. Kudos to the perseverance and talent of Taniel Winner for driving this collaboration with @gordonberman.bsky.social and Trisha Kesar. Individual differences in movement are real!
