New auditory layer-fMRI manuscript finds that:
-> deep layers contain content-specific predictions,
-> superficial layers contain prediction–input alignment,
-> all layers contain repetition suppression.

In a satirical commentary, @ofgulban.bsky.social examines the widening gap between traditional publication norms and emerging channels of science communication:

YouTube video by Layer fMRI Faruk Gulban: Meso-Vessel Imaging with 7 T MRI

Yesterday, @ofgulban.bsky.social gave a great talk about efficient imaging of small veins.
It was inspiring. Impressive how much information is there waiting to be harvested.

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 😊👍.

There is going to be an exiting workshop on advanced fMRI end of October in Erice, Sicily (Italy).

The agenda looks just at great as the location.

Häkkinen et al., investigated how to push layer-fMRI VASO at the next-Gen 7T (Feinbergatron) 7T scanner for layer-specific circuitry mapping. The fast gradients reveal temporal dynamics and connectivity with the cortex.

Ahmadi et al. focuses on the biophysical challenges and how to account for them. They show the feasibility of laminar specific VASO- disseminated across multiple clinical 7T scanners.

This thread reminds me on a satirical Blog post on this issue.

Maybe this one fits best here on the topic of bing noisy.

Thanks. I am glad we agree that the replication discussion was not about VASO then.

Kenshu Koiso (movies + newly faces/places), Insub Kim (orientation), Daniel Haenelt (ODC) compared MVPA across contrasts. Their results agree with you on vein effects in MVPA BOLD.

No 🌌 left, DM 4 🔗.

Fully agree. There was a slide on one of the layer-fMRI educationals at OHBM trying to get an overview of the layer field.
Attention (or what people call it to be) seems to be the least reproducible effect in the field.

It's not so easy.
It depends, if reduced sensitivity is coming from removing fasle-positive vein signals. VASOs sensitivity to micro vessels is not bad and often used for MVPA
Wasn't the replication issue in that study discussed wrt segmentation issues. If at all, VASO's T1 contrast helps with that

Hence use VASO :-)

For the laminauts. @layerfmri.bsky.social

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.

New layer-fMRI preprint looking at laminar response differences of across (very) early development in newborns.

This is a really nifty tool. Great to have it working for the lastest MacOS versions. Thanks Pete

I’m proud to share that on July 3rd, I defended my PhD thesis: "Distinct and complementary: insights on bistable perception in humans using ultra-high field MRI across multiple spatial scales."

The defense stream is here: youtube.com/live/J7wmn5s...

Excited for what’s next!🧠🧲🥳
