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!

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.

Happy 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.

We find that dynamic shifts in neural coding combined with stable population subspaces enable visual areas to concurrently represent sensory inputs and working memory without mutual interference.

Working memory is not steady state persistent activity, as once thought. Instead, it is dynamic with brief bouts of activity. Neural dynamics of visual working memory representation during sensory distraction www.biorxiv.org/content/10.1... #neuroscience

Taken together, we provide new insights into the functional laminar circuitry of the dlPFC and provide further support for a dynamic account of dlPFC coding.

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

We found three dynamic subclusters corresponding to each phase of the trial in the superficial layer, which might indicate separate WM control processes that occur on maintain WM content.

100

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

Finally, since the PFC is known for its dynamic coding, we wanted to see whether these dynamics are also present in a layer-specific manner when decoding WM load.

100

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

We additionally examined whether there are multivariate layer-specific differences across other phases of the working memory trial: e.g. encoding and retrieval. We saw that superficial layers had preferential decoding (of high vs. low WM load trials) during the retrieval phase.

100

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

However, we did not see any preferential layer-specific activation to the motor manipulation.

100

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

Since superficial layers of the dlPFC have previously been found to sustain elevated activity for the manipulation of WM, we thought that higher load might also induce higher activity during the delay. And that’s what we found.

100

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

So, in this study participants completed a delayed-match-to-sample task while being scanned at 7T. We manipulated the number of items participants had to remember (working memory load) and the motor response and examined the response from superficial and deep layers of the dlPFC.

Karolis Degutis @karolisdegutis.bsky.social · 30/10/2023

We know that the dlPFC is reliably engaged in working memory and, like other regions in the cortex, comprises of cytoarchitectonic layers. However, the functional role that these layers play in working memory subprocesses in humans is still not very well understood.
