Thinking about what brains are doing and how they ended up doing it.
🇩🇪 Postdoc in @sleeblab.bsky.social
🪲 Quantitative ethology, neuroethology and behavioural ecology
🔧 Developing open science software (mostly #rstats) and hardware
- This workshop was one of the highlights of my PhD! Highly recommend applying! Amazing science and amazing people allround - and all (reasonable) expenses paid!
- Junior scientists 👉 applications are open for our workshop on the mechanistic basis of #cognition. 🧠 🤝 Joint sessions with our #TheoreticalNeuroscience workshop ✈️ Hotel, meals + reasonable travel expenses covered Apply by May 7 ➡️ janelia.news/CNW26 @michaelreiser.bsky.social @jvoigts.bsky.social
- Reposted by Mikkel Roald-ArbølWe are responding to this call for evidence: ec.europa.eu/info/law/bet... Do you have concrete examples of the added value of #Rstats in the public or private sectors? Include the most important factors (risk, lock-in, security, innovation...) to assess the added value. Thanks!
- Does anyone here use or have used EthoVision XT and/or ANY-Maze, and could possibly share some sample data with me? I'm making functions for importing movement data into R, and these are tools that I have yet to cover, but I need some data to help me on! #animalbehaviour #neuroskyence
- Reposted by Mikkel Roald-Arbøl⚠️ New paper alert and what a way to end 2025! 🎉 Happy to share our story “Sleep-dependent infraslow rhythms are evolutionarily conserved across reptiles and mammals.” published today in Nature Neuroscience. Sleeping dragons 🦎 and functional ultrasound! Read the full paper here: rdcu.be/eWJHb 1/8
- Reposted by Mikkel Roald-ArbølMachine learning should not be a replacement for human judgment but rather help us embrace the various assumptions and interpretations that shape behavioral research, write Nedah Nemati and Matthew Whiteway. #neuroskyence www.thetransmitter.org/behavioral-n...
- Reposted by Mikkel Roald-ArbølDo you love quantifying animal behavior as much as we do? We have just the tool for you! Presenting #OCTRON - a pipeline that helps you create rich annotation data and enables training of custom segmentation models. Have a look, particularly if you work with non-model / invertebrate organisms!
- About to do a major documentation revamp for an R package. Does anyone know whether it's possible to use Quarto `.qmd` files for vignettes and articles? #rstats
- Reposted by Mikkel Roald-ArbølNew preprint: Neural manifolds that orchestrate walking and stopping Here we develop a new theory for neural generation of walking and how it can stop- Next we test the theory using Neuropixels probes in the lumber spinal cord of freely moving rats.

- ✨ Super stoked to announce that I will soon be joining the #SLEEB-Lab with @roesslerdaniela.bsky.social at @unibonn.bsky.social! Really excited for what’s to come!🕷️💤
- Two awesome news for our #SLEEB-Lab @unibonn.bsky.social 1) we finally had a lab photoshoot and 2) I can now officially announce @roald-arboel.com is joining our team as a Postdoc starting in November!!! Sweet tracking stuff ahead. Welcome to the #spider #behavior fam, Mikkel!

Her discoveries in the 1960s about how chimpanzees behaved in the wild broke new ground and represented what was called “one of the Western world’s great scientific achievements.” nyti.ms/42kpGxt
- Reposted by Mikkel Roald-ArbølI’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time! www.biorxiv.org/content/10.1...
- Reposted by Mikkel Roald-ArbølAnd we are live! Excited to announce the 2025 Multi-Agent Behavior Challenge on cross-lab supervised action recognition in mice 🐁🐀🖱️ Running on Kaggle until December 15th, with a $50,000 prize pool going to the top five submissions! www.kaggle.com/competitions...

This is in academia/.edu's new ToS, which you're prompted to agree to on login. Anyway I'll be jumping ship. You can find my stuff at hcommons.org.

- Reposted by Mikkel Roald-Arbøl🚨 PhD alert! IMPRS brain & behavior in Bonn just opened their calls for applications. Great PhD funding opportunities. Check it out! PS- I just joined their faculty, meaning you could do a rotation in my lab or even a PhD with me on spider sleep 🙃 Apply! 🚨
- 📢Apply now! Join our IMPRS for Brain&Behavior to pursue a #PhD in #neuroethology. Learn how brain circuits are linked to interesting animal behaviors! 📅 Deadline: October 31, 2025 🔗 imprs-brain-behavior.mpg.de #neuroscience #Neuroskyence #neurojobs #sciencejobs #PhDsky #PhDOffers #FundedPhD
