Cool new work from @dudman.bsky.social and @fluketc.bsky.social Reward magnitude determines reinforcement learning efficiency: www.science.org/doi/10.1126/...

Researchers have long searched for the neural circuit underlying locomotion. Now they’ve found it in flies. By @natmesanash.bsky.social #neuroskyence www.thetransmitter.org/systems-neur...

We tracked mice in space! This video shows our estimate of their self-induced centripetal force during circling in 3D 👩‍🚀 Preprint thread below 👇

Run, don’t walk, to your closest local preprint server to see our latest 3D tracking results! I’m still tickled that our results show flies don’t exactly walk, they “ground run” everywhere. I bet they also talk fast and suffer no fools.

New preprint: Whole-body 3D kinematics of freely behaving 𝐷𝑟𝑜𝑠𝑜𝑝ℎ𝑖𝑙𝑎 New tech from @blobology.bsky.social & others at @hhmijanelia.bsky.social, which @ispizua.bsky.social and @elliottabe.bsky.social used to gain insight into 3D structure of locomotion & courtship www.biorxiv.org/content/10.6...

Revision of @sarahpugly.bsky.social's 🪰 walking CPG preprint: www.biorxiv.org/content/10.1... Major updates: → motor rhythms replicate across 4 connectomes (incl. 2 new full-CNS datasets) → robust across all 6 legs → new analyses of the CPG motif show it's an outlier in the VNC → improved code docs

for the cpg curious, we made this video to explain the project www.youtube.com/watch?v=twAZ...

I got to nerd out with @seanmcarroll.bsky.social last week 😎

A new preprint shows that deep learning can make a fly walk realistically using a worm’s brain — exposing a fundamental problem with how connectome models are being built and sold to investors. By @natmesanash.bsky.social #neuroskyence www.thetransmitter.org/systems-neur...

If you're interested in emerging ideas in neural interfaces, I humbly suggest my lab's latest: www.nature.com/articles/s42... Neural interfaces create dynamic interactions between the brain & devices. This means mean we need new engineering approaches beyond typical ML to "decode" a static brain

Some of you saw a preview of this result at my Cosyne talk last week. We may have had too much fun working on this worm-fly model 🤣🤓🤣 (The digital sphinx may be imagery, but the lessons are real.)

🧵 New preprint led by @bingbrunton.bsky.social, @elliottabe.bsky.social, @lawrencehu.bsky.social We gave a worm brain control of a fly body and it walked What did we learn? Nothing, other than deep reinforcement learning is effective We call it the digital sphinx www.biorxiv.org/content/10.6...

🤓 Really excited to host this panel at COSYNE! Our incredible speakers Bing, Kenji, Kim & Saskia are sure to share insightful advice on making an impact in their career and community at every stage of their careers 🧑‍🔬 🧠

When a fly lands on your arm, how does your nervous system decide where to swat? By reconstructing tactile axons in a Drosophila connectome, we found a leg somatotopic map and downstream circuits that sample the map to initiate targeted grooming Led by Leila Elabbady, PhD doi.org/10.64898/202...

1. Kevin Gross and I have a new paper out today PLOS Biology. We used economic models based around screening games and the market for unpaid labor to highlight a meltdown cycle threatening peer review.

New preprint from the lab! A frontal motor circuit for economic decisions and actions: www.biorxiv.org/content/10.6... We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.

How do neural circuits generate the walking rhythm? Using connectome simulations, @sarahpugly.bsky.social found a minimal central pattern generator (CPG) that produces oscillations in leg motor neurons. Same circuit motif for each 🪰 leg. w @bingbrunton.bsky.social www.biorxiv.org/content/10.1...

thanks for speaking out @markhisted.org

Now out in @nature.com: Our study discovering a neural circuit in Drosophila that predictively inhibits proprioceptor axons during voluntary leg movements, such as walking and grooming. www.nature.com/articles/s41...

Embodiment is the concept that the function of the brain is inexorably shaped by the body, a lens that is often neglected when neuroscientists study specific brain subsystems, write @bingbrunton.bsky.social and @tuthill.bsky.social. #neuroskyence #neuroai www.thetransmitter.org/neuroai/brea...

my lab (www.tuthill.casa) at UW is hiring a research assistant/tech. basic scope is to apply machine learning/computer vision tools to measure and model 3D animal behavior and mechanics. we are a diverse, collaborative, curiosity-driven group. Apply: uwhires.admin.washington.edu/ENG/Candidat...

This shot of a little wattlebird might be the best single frame I shot in Australia. Can anyone help me with the banksia ID? 🪶 (You may need to click to view, given the aspect ratio.)

Epsilon 1 takes their reproducible experimental protocol very seriously 🤣

It seems to me that the time is ripe for a Bluesky thread about how—and maybe even why—to befriend crows. (1/n)
