Perceptual expectations and false percepts generate stimulus-specific activity in distinct layers of the early #visual #cortex https://www.biorxiv.org/content/10.1101/2022.04.13.488155v2 #7T layer-specific #fMRI of #V1 and #V2. #neuroscience

"results reveal a feedforward mechanism underlying false percepts, reflected by spontaneous stimulus-like activity in the input layers of the visual cortex, independent of top-down perceptual expectations."

Milestones and Applications of High-Resolution #7T MRSI
by Gilbert Hangel, PhD; et al. (Medical University Vienna, Austria).
The authors introduced a 7T MRSI method that combines free induction decay acquisition with concentric circle readout and short TE/TR that allows fast 3D coverage of the human brain.

This article demonstrates first results of applications in pathologies such as: brain tumors, multiple sclerosis, and epilepsy.

Are you interested in how #quantitative #MRI (#qMRI) parameters relate to #cell types estimated by #gene #expression in the #human #brain? 🤔

What impact have different #magnetic #field strengths (#3T, #7T)? 🧲

What do the different #relaxation and #MT parameters reflect? 📏
@LukeJoelEdwards and our team of collaborators were. You can now find some interesting answers published in https://doi.org/10.1093/cercor/bhac453

Why neuroenergetics is 🤙 brain stuff?

In my lab, we study the #neuroenergetics of the human connectome with multiscale brain imaging.

We have so many unsolved questions 😳:
How is energy distributed across the cortex and spent on higher cognitive functions? What are most expensive signaling pathways and mechanisms?

My lab is split between FAU and TUM (two best ranked German universities in case u didn‘t know yet 😅) and we use the following neuroimaging methods:

- functional and quantitative imaging on 7T MRI at FAU
- quantitative, molecular imaging on an integrated PET/MRI-scanner at TUM

The group at TUM is funded by an ERC-grant and i will start a new lab as Full Professor for multiscale neuroimaging at FAU in 2023.
