A Paradigm Change in Functional Brain Mapping: Suppressing the Thermal Noise in fMRI biorxiv.org/cgi/content/sh… #biorxiv_neursci

Mark your calendars; the next virtual layer-fMRI webinar is scheduled for April 20th. It will be about the connection of Cognitive Models and Cortical Layers. Speakers are Floris de Lange, Andre Bastos, and Michelle Moerel layerfmri.com/virtualevent3/

I am super excited to present a new stream of work at #OHBM2022 this year. Denis Chaimow, @karolisdegutis and I embarked on probing the prefrontal cortex layer-specifically with 7T fMRI (GE-BOLD & VASO). Curious? Then check out our 4 posters >> a thread <<

Here is a list of my favorite layer-fMRI abstracts and layer-fMRI lectures at this years OHBM: layerfmri.com/abstracts2023/

We are presenting our latest work at #OHBM2023 on in-vivo histology, high-resolution U-fiber mapping, laminar/columnar fMRI and even brain mapping in zoonotic diseases. Come and visit our posters if you are interested in these topics. More tweets with details coming up.

On today and tomorrow at #OHBM2023 are: „Cortical depth-dependence of ocularity decoding in high-resolution fMRI at 7T“ by Daniel Haenelt et al. (#1157) looks at how ocular dominance columns vary across cortical depth with 0.8mm resolution GE-/SE-echo and VASO sequences. 1/n

„Laminar spatiotemporal dynamics of CBV and BOLD signals using fast sampling at 7T fMRI in humans„ by Sebastian Dresbach et al. (#1299) on fast dynamics in laminar VASO/GE fMRI. Great collaboration inc. @seb_dre layerfMRI Also look at #145 by Gulban et al. for vessel effect 2/n

@seb_dre layerfMRI „Short-range connectivity within Broca's area“ by Juliane Damm et al. (#287) takes a fresh look at the language network using 0.8mm high resolution fiber tracking of short association fibers in Broca‘s area. Using the ultra strong gradients of our Connectom MRI. 3/n

@seb_dre layerfMRI „Brain mapping in zoonotic diseases: Neuroinfectiology of Bcbva in chimpanzee brains“ by Carsten Jäger et al. (#1000) showcases how brain imaging can help in understanding zoonotic disease. 4/n

@seb_dre layerfMRI More on laminar fMRI: „Dissociating feedforward and feedback signals in FFA and PPA during perception and imagery“ by Tony Carricarte et al. (#84) 5/n

New layer-fMRI preprint looking at the laminar processing of mental imaginations of faces and scenes in FFA and PPA. By Tony Carricarte et al., doi.org/10.31234/osf.i…
