How do you correct for the well-known bias toward superficial layers in laminar BOLD fMRI? We report simulations and real 7T data. TLDR: Some published methods do not actually correct the issue, but we find two metrics that do seem to work. biorxiv.org/content/10.1101/… Thread here:

What lies between grey and white in our #brain? It is...🥁the superficial white matter! @NikWeiskopf & Evgeniya Kirilina made this region visible in the living human brain🧐They found also that it contains a lot of iron. Out now in @ScienceAdvances: tinyurl.com/yxjgcpxx

Frontotemporal dementia (FTD) is caused by damage to cells in areas of the brain called the frontal and temporal lobes. Dr. Rowe is busy finding ways to protect these precious cells.

7T MRI: from hope to reality, as the UK7T multicentre protocol shows greater reproducibility for QSM and R2* at 7T versus 3T. Excellent ICC>0.9 between sites. A green light to mutlicentre applications for dementia research @cat_rua @wbic_cam #UK7T

The next virtual layer-fMRI webinar is scheduled for Sept 28th.
It will be about bridging the gap between depth-dependent fMRI and electrophysiology.
Speakers are Kamil Ugurbil, Lucia Melloni, and Seong-Gi Kim.

New layer-fMRI paper investigating how recurrent superficial connections are modulated by learning. A layer-fMRI application study using MVPA analyses and an orientation discrimination task. doi.org/10.1016/j.cub.2020.0…

There is much (!) more to cortical layers than you can get from even ultra-high field MRI.
Here is a fantastic overview. from the late Karl Zilles on the cyto-, myelo-, receptor- and synaptic architecture in human cortical areas

Mark your calendars: this is gonna be an exciting layer-(f)MRI event.
Next year's meeting will be held at the DZNE in Magdeburg, Germany! The theme will be 'The Micro-cortex in Health and Disease'. Check out the homepage for more information: estherkuehn-science.org/bid-…

Congratulations to Dr Chris Rodgers, Head of 7T Physics at WBIC, on his new *Readership* in Biomedical Imaging @Cambridge_Uni for leadership and innovation in ultrahigh field imaging. A great colleague and collaborator @wbic_cam #UK7T @wellcometrust @CambridgeBRC

New layer-fMRI manuscript about an open and modular software suite that is explicitly dedicated for layer-fMRI.

Exciting sequence from Ruediger Stirnberg at @DZNE_de
The flexible combination of multi-shot excitation and CAIPI-undersampling will boost future layer-fMRI signal quality. One can just ‘choose’ the desired spatial resolution, despite T2*-contratins. doi.org/10.1101/2020.06.08.1…

New paper now published in NIMG on using strong gradients of CUBRIC Connectom scanner for diffusion weighting in conjunction with susceptibility effects to separate GE signals from intra- and extra-axonal compartments in white matter . doi.org/10.1016/j.neuroimage…

Really proud of @GillesdeH for pulling off 7T-fMRI of Ocular Dominance Columns and Laminae in V1! In this collaboration between Amsterdam and Beijing (Chinese Academy of Sciences and @SpinozaCentre), we dissociated bottom-up and top-down processing *inside* the brain.

New Layer-fMRI preprint from the Cambridge group. They investigate suppressive recurrent feedback across layers in adaptive processing with GRASE, GE-EPI signals, and with connectivity analysis tools. doi.org/10.1101/2020.02.14.9…
