Clinical 7T gradients can go fast — but peripheral nerve stimulation (PNS) stops you at high-res fMRI. ⚡ Meet POPE 🌍: we reshape EPI pulses to dodge PNS exactly when it spikes → robust 0.3mm fMRI, seeing intracortical veins. 🧠 w/ @SiemensHealth 👉 doi.org/10.64898/202...
Finally, today is the day: Josefine Zerbe will present and release our new multi-echo 7T fMRI dataset LAION-fMRI during #VSS2026, with >30 fMRI session per subject and unprecedented stimulus diversity. Come to Talk Room 1 (Scene perception) today at 5:15. Details will follow in a separate thread!
Check out our newest demonstrating feasabilty of sub-mm whole brain EEG-fMRI at 7T. Happy to have been part of this amazing collaboration and thank you so much to Cristina and João for leading this project 😊👍.

Get ready for the biggest #ABIM yet! 🥳 We're celebrating our 20th anniversary with a special edition you won't want to miss. 🗓️ Registration & abstract submission: www.unige.ch/ABIM/partici... 💰Early bird fee ends November 9th! #ABIM2026 #neuroimaging
We’re looking for a postdoc to join our Max Planck group in Germany some time in 2026. If you have computational and/or neuroimaging expertise, and are interested in questions intersecting perception and cognition, please reach out! I’ll also be happy to chat at the #Bernsteinconference this week.
Incredible study by Raut et al.: by tracking a single measure (pupil size), you can model slow, large-scale dynamics in neuronal calcium, metabolism, and brain blood oxygen through a shared latent space! www.nature.com/articles/s41...
What started as a journal club on layer decoding turned into a project thanks to @karolisdegutis.bsky.social. Our preprint challenges a widespread assumption in the field: MVPA is not immune to vascular confounds in laminar GE-BOLD decoding, as shown using a mechanistic laminar response model.
Karolis Degutis@karolisdegutis.bsky.social · 11mo agoHappy to see this out: our new preprint shows that laminar GE-BOLD fMRI decoding isn’t immune to vascular draining biases. Simulations reveal false positives due to multivariate signal spread across layers, but oversampling + deconvolution can (sometimes) improve specificity.

Very happy to share our work on the neural dynamics of visual working memory maintenance during sensory distraction; now out as a VOR on eLIife: elifesciences.org/articles/99290
Neural dynamics of visual working memory representation during sensory distraction
Dynamic shifts in neural coding combined with stable population subspaces enable visual areas to concurrently represent sensory inputs and working memory without mutual interference.

Excited to share our latest preprint: "Challenges in replicating layer-specificity of working memory processes in the human prefrontal cortex.”, where we attempted to replicate layer-specific fMRI findings in the human dlPFC during a working memory task. www.biorxiv.org/content/10.1...
Challenges in replicating layer-specificity of working memory processes in human dlPFC
Although working memory reliably activates the dorsolateral prefrontal cortex (dlPFC), the functional significance of its distinct cytoarchitectonic layers is not well understood in humans. A recent f...
