This is one of my favourite things ever. From the awesome @kristorpjensen.bsky.social

www.bbc.com/news/article... science ftw! Amazing work described here.

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

GUESS WHAT WEEK IT IS

Tenure-track Assistant Professor in Computational Ecology and/or Evolution @columbiauniversity.bsky.social. Deadline to apply September 30. Reach out if you have questions. apply.interfolio.com/172496

Of 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 share that my new postdoctoral position is going so well that I submitted a new paper at the end of my first week! www.biorxiv.org/content/10.1... A thread below

My new essay for @thetransmitter.bsky.social. Why is understanding emotion so challenging? The debates around what counts as an "emotion" shed insight. These disputes are multidimensional, principled and fascinating. Here, I unpack them. www.thetransmitter.org/the-big-pict...

How the brain coordinates the activity of its many muscles to achieve successful control remains an enigma. www.cell.com/issue/S0896-...

Something exciting just left the gym -- meet Arnold the first generalist musculoskeletal control policy! The human body has 600+ muscles, yet we seamlessly coordinate them for everything from whispering a syllable to felling a forrest. How? www.arxiv.org/abs/2508.18066

Thrilled to share this work, long time in the making! Carried through creatively by @siddjakes.bsky.social after initial design & piloting by @trackingskills.bsky.social, with help from @trackingactions.bsky.social. Modeling in collaboration with Massimo Vergassola & Nicola Rigolli.

Forelimb movement control at the basal ganglia - brainstem interface! Happy to finally share this work from me and @harsh-kanodia.bsky.social with Silvia Arber! @biozentrum.unibas.ch @fmiscience.bsky.social www.nature.com/articles/s41...

ISTA scientists and Google Research unveil LICONN: a new expansion microscopy method that can reconstruct mammalian brain tissue with full synaptic detail using light microscopes. This method could transform how we study the brain’s networks. @nature.com Read more: https://bit.ly/44f0euV

Our paper is out in Nature. By examining various inputs to the motor cortex during learning, we found that thalamic inputs learn to activate the cortical neurons encoding the movement being learned. Tour de force by Assaf in collab with Felix and Marcus. Congrats! www.nature.com/articles/s41...

Choose Science. Choose Europe. A new Marie Skłodowska-Curie Actions Postdoctoral Fellowships 2025 call is now open. With a budget of €404.3 million, it will support around 1,650 researchers from Europe and beyond. Apply by 10 September → europa.eu/!fBTMgF

Excited to share our newest publication as my first post on BlueSky!! www.nature.com/articles/s41...

Our paper from the Cerebellum Cell-types Classification Collaboration (C4) is now out in Cell! All data and software to run the classifier are available at www.c4-database.com. Open-access link to the paper: authors.elsevier.com/c/1khABL7PXu...

My lab has several postdoctoral fellow and software engineering positions available. Please email me if you’re interested.

We are excited to announce our new Simons Collaboration on Ecological Neuroscience (SCENE)! This program will unite experts in experimental and computational #neuroscience approaches to investigate how the brain represents sensorimotor interactions. www.simonsfoundation.org/2025/04/24/s... #science

✨ Introducing a new #SOTA action recognition large multimodal language model: #LLaVAction! By @shaokaiye.bsky.social Haozhe Qi, @trackingskills.bsky.social and me! 📝 arxiv.org/abs/2503.18712 🤖 mmathislab.github.io/llavaction/ 1/n

I heard about this cool work from @trackingskills.bsky.social ingskills.bsky.social during my recent EPFL visit. Embarrassingly, I hadn't heard of proprioceptive illusions—vibrations on muscles/tendons inducing them! Here, Alex & team model how primary afferents alone can explain these illusions.

Thanks @ardemp.bskyverified.social for an inspiring visit!

Thanks @trackingactions.bsky.social for being a generous host and @trackingskills.bsky.social for pouring wine for the fantastic @epfl-brainmind.bsky.social visit. Days like this remind me how lucky we are as scientists. Loved the student lunch, 1:1s, seminar reception, and dinner!
