Are you interested in human vision perception study with layer-fMRI? Come to our poster #2557 🧠🌈 OHBM

For an ERC-funded project I am looking for enthusiastic academics interested in investigating mental imagery using laminar fMRI, AI and BCIs. For details see: academictransfer.com/en/342721/phd-… academictransfer.com/en/342769/post…

🚨New preprint🚨 on laminar CBV and BOLD responses across time and space in human S1 at 7T. We investigated digit-representations across layers and observed indications of a potential center-surround excitation-inhibition architecture that changes across the cortical landscape.

New layer-fMRI preprint investigating the venous vascular bias across subfields of Hippocampus. By Viktor Pfaffenrot et al., doi.org/10.1101/2024.0…

New layer-fMRI preprint looking at the different orientation dependence of 2D-EPI, 3D-EPI, and bSSFP. By Dana Ramadan et al., doi.org/10.1101/2024.0…

Please mark your calendars for the 7th ‘layer-fMRI’ virtual dinner on Aug. 22nd. We will be discussing possible translational and clinical applications of layer fMRI. With: Esther Kuehn, Joost Haarsma, and Jun Hua More info: layerfmri.com/7thdinner/

New layer-fMRI paper proposes how to reduce vascular biases by means of using respiratory signals. By Yuhui Chai (Yuhui Chai) et al. doi.org/10.1162/imag_a…

New layer-fMRI preprint using previously acquired 3T fMRI with simultaneous EEG characterize feature specific oscillations across cortical depth. By Tommy Clausner et al. doi.org/10.1101/2024.0…

This layer-fMRI is now published in ImagingNeuroscience: doi.org/10.1162/imag_a…

A couple of layer-fMRI jobs to work on the Feinbergatron; a scanner designed for layer-fMRI.

New paper in Imaging Neuroscience by Sebastian Dresbach, Rainer Goebel, et al: Characterisation of laminar and vascular spatiotemporal dynamics of CBV and BOLD signals using VASO and ME-GRE at 7T in humans doi.org/10.1162/imag_a…

This event starts in 2 hours. Please join.

New PhD position for layer-fMRI representations of the "movement sense" (stimulated and active hand movements) with data acquisition at MGH (Boston) and NIH (Bethesda) r.jyu.fi/FD6 The position is with Harri Piitulainen in Jyväskylä, Finland

Here is a link to talk I recently gave on layer fMRI. I discuss some of the potential pitfalls of layer fMRI, the type of inferences one can make, and how it might help us to understand things like hallucinations. Hope it is of interest to some of you! youtu.be/gQl8ZcQevdM?si…

New layer-fMRI manuscript focusing on Fuzzy Ripple artifacts. Arguably the biggest challenge in layer-fMRI acquisition. Every layer-fMRI dataset has them, they limit resolution and TR, and we shows how to mitigate them. doi.org/10.1101/2024.0… #Layer_fMRI_Artifact_of_the_Week

You feel something is physically moving during a bistable illusion. While your brain can trick your eyes 👀, it cannot trick our scanner🧲 Our 7T fMRI results show a distinct feedback modulation between V1 & hMT+ in this illusion👇 Faruk Gulban layerfMRI Judith Peters Rainer Goebel

Happy to see that this work is now out in Communications Biology! nature.com/articles/s4200… We show that the layers of the PFC have distinct laminar activation profiles to working memory load and also provide evidence that this code is dynamic.

New layer-fMRI manuscript comparing functional quantitative susceptibility mapping (fQSM) with other contrasts. fQSM can account for some of the vein bias. By Straub et al. doi.org/10.1101/2024.0…

New layer-fMRI manuscript proposing an efficient 3-min methods to capture whole brain structural reference data with matched distortions: T1234. This sequence captures layer-fMRI signals in EPI space more accurately. By Kenny Kan et al., doi.org/10.1101/2024.0…
