- Reposted by Matt Perich🚨📜+🧵🚨 Very excited about this work showing that people with no hand function following a spinal cord injury can control the activity of motor units from those muscles to perform 1D, 2D and 3D tasks, play video games, or navigate a virtual wheelchair By a wonderful team co-mentored w Dario Farina
- New preprint! We show that people with tetraplegic spinal cord injury can use their residual motor unit activity to achieve up to three dimensional control using non-invasive high-density surface EMG With my co-first authors Xingchen Yang and Ciara Gibbs www.medrxiv.org/content/10.6... 1/13
- Go work with Juan! I can vouch that this will be a very cool project.
- Super happy for having been awarded an @erc.europa.eu Consolidator Grant to continue our basic neuroscience work on the neural basis for motor control and motor learning. What a great way to set things up here at Champalimaud! 🎉 🚨 Job Alert for postdocs research technicians, and PhD students in 🧵
- Reposted by Matt Perich🚨Job alert🚨 The lab has up to *3 postdoc openings* for comp systems neuroscientists interested in describing and manipulating neural population dynamics mediating behaviour This is part of a collaborative ARIA grant "4D precision control of cortical dynamics" euraxess.ec.europa.eu/jobs/383909
- If you're interested in dynamical systems analysis for neuroscience, definitely check out @oliviercodol.bsky.social 's revised version of our RL paper! Very cool results in the new Fig 6, worth it regardless of if you saw our previous version or if it's all new. www.biorxiv.org/content/10.1...
- A big "get" for the Champalimaud! Excited to see what comes out of the Warehouse and the next phase of Juan's lab
- Reposted by Matt PerichVery excited and proud to share my postdoctoral research with @neurrriot.bsky.social looking at the context-specific encoding of social behavior 💃🕺 in hormone-sensitive, large-scale brain networks in mice! www.biorxiv.org/content/10.1... #neuroskyence #compneurosky 🧪 1/12
- Reposted by Matt PerichOf potential interest to those keen on motor control and/or multi-task networks. Congrats to Elom and Eric. www.biorxiv.org/content/10.1...
- 🚨 I’m excited to say that my CIHR Project Grant was funded! My NHP lab is now full-speed-ahead, and I’m hiring experimentalists (postdoc, PhD student, and/or a tech/manager). We’ll do multi-region ephys during reaching/grasping in macaques, with behavioral and spinal perturbations.
- IMO Montreal is one of the best cities out there for neuro, and everyone in my lab will get to enjoy learning from and interacting with the NeuroAI folks at Mila. If modeling the computations behind multi-modal sensorimotor integration and adaptation is of interest to you, please reach out!
- More info on our funded project is here: webapps.cihr-irsc.gc.ca/decisions/p/.... In many ways, this directly follows our 2020 paper: www.biorxiv.org/content/10.1.... But we have much broader ambitions too and are building a flexible platform for NHP motor ephys. Should be a fun 5 years!
- Awesome work from @juangallego.bsky.social and lab. An interface from single motoneuron control in tetraplegia!
- 🚨 New preprint + thread 🧵 We've gone back to studying motoneuron control principles and their applications & here's paper #1: A proof-of-concept study showing that people with tetraplegic spinal cord injury can control up to 2DoF from a single intramuscular implant www.medrxiv.org/content/10.1...
- Reposted by Matt PerichCheck out @jordancollver.bsky.social’s great illustration of modular RNNs training to work like a bio-brain🦾🧠 Thanks to Crearte for featuring our collaboration! www.instagram.com/crearte.ca/p...
- Reposted by Matt PerichVery happy about my former mentor Sara Solla having received the Valentin Braitenberg Award for her lifelong contributions to computational neuroscience! Sara will be giving a lecture at the upcoming @bernsteinneuro.bsky.social meeting which you shouldn't miss. bernstein-network.de/en/newsroom/...
- 📰 I really enjoyed writing this article with @thetransmitter.bsky.social! In it, I summarize parts of our recent perspective article on neural manifolds (www.nature.com/articles/s41...), with a focus on highlighting just a few cool insights into the brain we've already seen at the population level.
- Neural manifold properties can help us understand how animal brains deal with competing and multifaceted information, execute flexible behaviors and reuse common computations, writes @mattperich.bsky.social. #neuroskyence www.thetransmitter.org/neural-dynam...
- Thanks to @emilysingerneuro.bsky.social for another opportunity to work with The Transmitter (which is an awesome publication), and of course the many, many long conversations on manifolds with @juangallego.bsky.social that shaped these articles 🙂
- Reposted by Matt Perich🚨New paper🚨 Neural manifolds went from a niche-y word to an ubiquitous term in systems neuro thanks to many interesting findings across fields. But like with any emerging term, people use it very differently. Here, we clarify our take on the term, and review key findings & challenges rdcu.be/ex8hW
- Reposted by Matt Perich'manifolds', and the overall conception of the brain using a dynamical systems framework, have come a long way.
- Check out our new review/perspective (w/ @juangallego.bsky.social & Devika Narain) on neural manifolds in the brain! It was a lot of fun to think through these ideas over the past couple of years, and I'm excited it's finally out in the world! 🔗: www.nature.com/articles/s41... 📄: rdcu.be/ex8hW

- A lot has changed since we wrote our last perspective piece in 2017 (www.cell.com/neuron/fullt..., both in how we think about neural manifolds and in the prevalence in the field. We hope this paper provides a good primer for the ideas, and points towards some big open questions in this space.
- Reposted by Matt PerichFinally out! Eight years after initiating this study with Simon Borgognon, Nicolo Macellari, and Gregoire Courtine, we have uncovered neural population dynamics shared among premotor, motor, and somatosensory cortices during various types of locomotor tasks. www.nature.com/articles/s41...
- Our new approach for scalable, generalizable, and efficient neural population decoding is now online! Here we focus on real-time BCI but I'm excited about all of our next steps building on this. Awesome work led by @averyryoo.bsky.social @nandahkrishna.bsky.social @ximengmao.bsky.social
- Reposted by Matt PerichVery late, but had a 🔥 time at my first Cosyne presenting my work with @nandahkrishna.bsky.social, Ximeng Mao, @mattperich.bsky.social, and @glajoie.bsky.social on real-time neural decoding with hybrid SSMs. Keep an eye out for a preprint (hopefully) soon 👀 #Cosyne2025 @cosynemeeting.bsky.social
- Reposted by Matt PerichMany apparent disagreements over the utility of neural manifolds come from a lack of clarity on what the term really encompasses, argues @mattperich.bsky.social #neuroskyence www.thetransmitter.org/neural-dynam...
- Reposted by Matt Perich🧠 Our new (NIH funded!) paper reveals how the brain creates internal dynamics during both real- and imagined navigation. We recorded directly from the human hippocampus as participants moved through physical space and when they mentally navigated imagined routes. www.nature.com/articles/s41...
- Reposted by Matt PerichWant to hear more about how feedback can guide learning in RNNs for motor adaptation. Here is our new paper in Nat. Com. with Barbara Feulner and @juangallego.bsky.social www.nature.com/articles/s41...
- Reposted by Matt PerichOur paper from Junchol Park and collaborators that has been brewing for a while. Trying to capture our thinking about what action specification in striatum means and what would constitute evidence for such a model. Longer thread soon, but it’s online now. www.cell.com/neuron/fullt...
- Great initiative! The Transmitter is awesome.
- I'm excited to share another project we've been working on: The Transmitter's first book, which includes some of our favorite essays from our first ~9 months. Download a copy here: www.thetransmitter.org/transmitter-...
