Wondering whether insight is more likely after sleep? Check out our pre-print and Anikas summary below. That was fun Anika Löwe & Nico Schuck & twitterless Maria Tzegka!

What began as a slightly intoxicated walk on Huntington beach in California with my buddy @b_j_griffiths last summer, ended in a published paper today in Communications Psychology. (1/7)

✨ New (updated) preprint! ✨ We find that "Replay in human visual cortex is linked to the formation of successor representations and independent of consciousness"! 🧠 Fabulous team work with Lena Krippner, Dr. Christoph Koch & Nico Schuck! 🌟 🧵 👇 [1/5] biorxiv.org/content/10.110…



#CogNeuro seeks unified theories of behavioral, physiological, and mental states. To this aim, our Nature Neuroscience Perspective proposes a new framework centered on #TaskDemands & across-task generalization. nature.com/articles/s4159… w/Alexandra C Schmid Simon Kaplan Chris Baker D.Kravitz🧵

Excited to be in Boston for CogCompNeuro 2024 to discuss how WM retrieval impacts LTM at our poster today! Also, check out our collaborative work on evaluating vision models 🤖 with a new multi-level similarity judgment dataset (A113), presented by Lukas Muttenthaler & Andrew Lampinen.

Do we learn differently from surprises as we age? We asked this using a RL task that deconfounded outcome probability & PE magnitude. Older adults learned more from large PEs than young adults. t.ly/DhjLo Fun teamwork w Dr. Christoph Koch Ondrej Zika Rasmus Bruckner

If you'd like a quick read on your coffee break, check out our new Trends in Cognitive Sciences article on active forgetting during sleep doi.org/10.1016/j.tics…



1/7: We are excited that our paper "Single-neuron representations of odours in the human brain" was published today in nature. @humansingleunit,RWTH Aachen Rheinische Friedrich-Wilhelms-Universität Bonn, @MarcSpehr, Kat, University of Oxford, Oxford Neuroscience, #Olfaction Link: t.ly/7kioB

Does sleep free cognitive resources for efficient next-day processing? Are processing capacities similar in human and rodent sleep? How does the sleeping brain balance efficiency and robustness? New paper led by Michael Hahn to answer these questions. sciencedirect.com/science/articl… (1/6)


Excited to announce Centaur -- the first foundation model of human cognition. Centaur can predict and simulate human behavior in any experiment expressible in natural language. You can readily download the model from Hugging Face and test it yourself: huggingface.co/marcelbinz/Lla…

🚨 New preprint on the role of eating disorder symptoms in accelerating response vigor during foraging decisions 💫 w/ Sam Hall-McMaster 📜Link: osf.io/preprints/psya… 💻Code and data: github.com/ozika/ed-forag… Funded by Humboldt-Stiftung Max Planck Institute for Human Development

This is finally out today in PLOS Comp Biol - find the final updated and improved version here: journals.plos.org/ploscompbiol/a… with Nico Schuck summerfieldlab @summerfieldlab.bsky.social Andrew Saxe Paul Muhle-Karbe and twitterless Léo

Now online in Current Biology ! 📢💥 Using 7T precision fMRI, we discovered new organizational principles of human entorhinal cortex and of human hippocampal-entorhinal system. doi.org/10.1016/j.cub.… With DoellerLab, Menno Witter, Daniel Margulies, Cognitive Neuroanatomy Lab. 🧵👇 1/5


Our Trends in Neurosciences review on task representational spaces in OFC/vmPFC and in deep RL models is now out! Had a great time working on it with Nir Moneta and Nico Schuck, check it out here: cell.com/trends/neurosc…
