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

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.

Here is a list of my favorite layer-fMRI abstracts and layer-fMRI lectures at this years OHBM: https://t.co/CaVdVpTT7x

[layerfMRI @layerfMRI]

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

A Paradigm Change in Functional Brain Mapping: Suppressing the Thermal Noise in fMRI https://t.co/tKQHasoKWP #biorxiv_neursci

[Denis Chaimow @DenisChaimow]

@layerfMRI Small clarification: It doesn‘t simulate sequence parameters but it takes (among other things) imaging specific parameters like PSF width, response amplitude and noise characteristics and simulates imaging and analysis of column patterns. Thanks @layerfMRI for the tweet!
