Time for a #tweeprint! What's the difference (in motor cortex) between performing an action and just imagining it? Turns out, quite a bit (but also, pretty much nothing...)! biorxiv.org/content/10.110… RNEL Jen Collinger Raeed Chowdhury Aaron Batista Byron Yu (1/8)

Ida Momennejad David Sussillo FieteGroup Stefano Fusi Tagging Matt Perich and Juan Álvaro Gallego -- that duo has done a lot of work (imo thoughtful, yet relatively under-appreciated) in this area. Ida Momennejad writes amazing papers that often straddle many fields, incl ours; Matt and Juan, perhaps y'all could help flesh out this list?

Kanaka Rajan Ida Momennejad David Sussillo FieteGroup Stefano Fusi Matt Perich Thanks Kanaka 🥰 I guess it's self-promotion time… Ida Momennejad here is a short thread on a few things that Matt Perich and I have ve done together (most including Kathleen Cullen Sara A Solla and also Raeed Chowdhury and more…) 1/

Excited to announce “A neural basis of choking under pressure” is up on biorxiv, where we look at motor cortical population correlates of reward-mediated performance in primates. biorxiv.org/cgi/content/sh… Summary in thread below (1/11)

🚨Tweetprint time! 🚨 We studied how de novo motor learning alters the underlying neural activity & affects motor adaptation using RNNs 📜 t.ly/vSLo Special thanks to coauthors Matt Perich Kathleen Cullen Juan Álvaro Gallego ClopathLab Pls read 🧵 + RT! 1/n

🚨#tweetprint time! 🚨🎉 📝 tinyurl.com/nonlinearmanif… We tested the hypothesis that due to the nonlinear responses of single neurons and the intricate connectivity of brain circuits, neural manifolds would be nonlinear. (1/17)

I still can’t process it. He once caught me after a committee meeting to congratulate me. I thought he was talking about a recent paper, but he was talking about my wedding 😬 I was looking forward to catching up at the next conference. My heart goes out to his wife and kids 💔

Paper time! If you train a neural decoder to predict actions or EMG from neural activity, you'll probably soon realize that a day or two later it stops working: neural recording devices move, and you lose your original pool of neurons or plane of focus.

Ever wondered whether the dynamics learned by LFADS-like models could help us understand neural computation? Chethan Pandarinath,Andrew Sedler, Jonathan McCart, and I developed ODIN to robustly recover latent dynamical features through the power of injectivity! 📜 1/ arxiv.org/abs/2309.06402…

People ask me all the time if I am "pro-Israel" because I am a Jew who has lived in Israel, and my answer is that being "pro-Israel" or being "pro-Palestine" or being a "Zionist" does not properly capture the nuance of thought most people do or should have about this issue. It

Really excited to attend SfN for the first time! #SfN23 I will share our work on nonlinear manifolds, and how we are planning to expand to high-dimensional behaviour and sensory areas. Save some energy for Wednesday afternoon! 😊

Are you at #SfN23 and interested the neural activity behind feedback-driven arm movement? Stop by my poster on Tuesday morning (FF23, 8am-12pm) to see how it compares with activity during feedforward dominated movements!

So fortunate to lead an amazingly talented lab. These folks are 𝒄𝒓𝒂𝒏𝒌𝒊𝒏𝒈 𝒐𝒖𝒕 great science. 🧵 of must-see posters, which span NeuroML / AI, clinical BCI (+BrainGate Team), population dynamics, 2P Ca imaging, spinal pattern generation, EMG… 🧠🔬👩‍🔬👨‍🔬📈 #SfN23 ⬇️

As some of you are well aware, the BRAIN Initiative funding was cut by 40% (braininitiative.nih.gov/news-events/bl…). “This is truly awful, This large cut to the BRAIN Initiative is, simply put, going to kill jobs and hurt patients over the next 10-20 years.” – Kip Ludwig, PhD

Since the lead author (Patrick Marino) is too cool for social media, it falls on me to tweeprint about our new article “A posture subspace in primary motor cortex”, which just dropped on biorxiv yesterday! (1/9) biorxiv.org/content/10.110…

The final version of Mehrdad Kashefi's paper investigating how people plan future reaches while reaching has now been published. 🥳elifesciences.org/articles/94485

If you're interested in our findings or the topic of online planning more generally, there is also a great insight piece by Raeed Chowdhury accompanying the publication! Thanks Raeed for taking the time! elifesciences.org/articles/101739

Learned yesterday about a literal monkey island—they have their own little society there! To be one of the scientists to study them there would be thrilling, in every sense of the word 😬 #SimCo24 youtu.be/9flGNXR2zTA?si…

When you perform a sequence of actions, you are always dual-tasking: You produce a movement and at the same time plan future ones. Check out Mehrdad Kashefi's new paper (with Andrew Pruszynski). Thanks to Raeed Chowdhury for an excellent insight! elifesciences.org/articles/101739

Excited to share my latest work with @[email protected] and Andrew Pruszynski. In this work, we ask whether motor sequence learning is motoric at all! Check out the 🧵version of the abstract: biorxiv.org/content/10.110… 1/n
