Forschungszentrum Jülich’s Post

A new release of the Julich Brain Atlas has been published! 🙌 The updated brain atlas now provides online access to 52 new probability maps of cortical and subcortical structures in a three-dimensional reference space. Want to know more about the Julich Brain Atlas? 🧠 Check out our video with Hector Fellow Prof. Dr. Katrin Amunt, where she explains her research on mapping the human brain and developing the brain atlas. 👉 https://lnkd.in/eAX-mZmZ

Electron microscopy is a powerful technique that uses electrons instead of light waves to visualize structures, revealing incredible detail. In this image even in a dense sample (gray), we can see the detail of a single neuron (yellow). This visualization is made from a publicly available data collection called MICrONS. In a five-year collaboration between the Allen Institute for Brain Science, Princeton University and Baylor College of Medicine, funded and coordinated by IARPA, scientists and engineers mapped fine structures, and connections and functional properties in a tiny piece of the mouse brain from the visual neocortex, the part of the brain that processes vision.

Are you tired of vague and task-uninformed definitions of intrinsic brain networks? Discover our latest #preprint on visuospatial attention networks – Atlas for the Lateralized Visuospatial Attention Networks (ALANs): Insights from fMRI and Network Analyses. We address the gap in understanding the lateralization of visuospatial attention networks through an innovative multimodal approach. By examining a homogeneous sample of 130 right-handed individuals typically brain-organized for language, we applied the line bisection judgment task alongside resting-state fMRI data analysis to identify and analyze the lateralized brain regions and networks involved in visuospatial attention. We identified 95 lateralized regions organized into five networks, demonstrating the critical roles of the ParietoFrontal and TemporoFrontal networks. Our findings challenge existing paradigms and offer a comprehensive atlas (ALANs) for future research into the variability and mechanisms of hemispheric specialization in visuospatial attention.
