Dynamic patterns of functional connectivity observed in rat fMRI signals (left) can be reconstructed as the superposition of macroscale stationary waves resonating transiently over time (right). Find out more at nature.com/articles/s4146…! Shemesh Lab Francisca Fernandes ICVS ChampalimaudResearch

(1/3) SynthSeg 2.0 is finally out on PNASNews and publicly available on FreeSurfer (surfer.nmr.mgh.harvard.edu/fswiki/SynthSeg). It segments clinical brain MRI of any orientation, resolution and pulse sequence. The output is always at 1x1x1mm resolution, no matter what the input resolution is.

🎉🎉🎉🍻Our paper is now out in Biological Psychiatry! Check out Alex's tweet for a thread with our findings. I’m incredibly grateful to work with such amazing people! Thank you Alex Fornito, Jan Buitelaar and Marianne Oldehinkel for all your guidance and support!

LEiDA is having kids! 🧠😂 Our method Leading Eigenvector Dynamics Analysis has been extended to consider BOTH the first AND second eigenvectors, capturing in this way ALL phase relationships at each time point in a very elegant formal analysis. Well done!

It is finally out! Check out our project to bring generative models to ProjectMONAI and help develop several medical imaging tasks such as image synthesis, anomaly detection, denoising, super-resolution, MRI reconstruction, and more! github.com/Project-MONAI/…

Everything you ever wanted to know about Self-Supervised Learning but were afraid to ask. A giant cookbook of SSL recipes. By a large crowd from Meta-FAIR with various academic collaborators led by Randall Balestriero and Mark Ibrahim. arxiv.org/abs/2304.12210

Mental illness is a brain disorder? Right? We thought so. Hang on though, our new study JAMA Psychiatry shows that poor body health is a more pronounced manifestation of mental illness than poor brain health. jamanetwork.com/journals/jamap… 🧵1/9

You can now run FreeSurfer recon-all on clinical scans of any resolution of contrast. You get all the same surfaces / parcellations / segmentations / etc. Code: surfer.nmr.mgh.harvard.edu/fswiki/recon-a… Paper: arxiv.org/pdf/2305.01827… Work with Karthik Gopinath Sudeshna Das, PhD and others.

One hundred years of wave equations of physical systems from Schrödinger's model of the atom to neural field theory of the brain Both formulations predict that the system's expressed energy is constrained into natural modes - "eigenstates - determined by the system's geometry

A preprint of our work is out! We build dynamical models of the low dimensional manifold brain modes, i.e. a reduced number of abstract variables each encoding the simultaneous dynamical behaviour of multiple macroscopic brain regions biorxiv.org/content/10.110…

New tool WMH-SynthSeg for joint segmentation of brain regions and white matter hyper-/hypo-intensities in high- and low-field MRI (including portable MRI, eg Swoop® Portable MR Imaging® System–Hyperfine, Inc).

Ho ho ho, after weeks of validating: the Xmas release of #FastSurfer is out: Version 2.2. was released today! It fixes an issue with the eTIV among other improvements. Try it out and let us know what you think. github.com/Deep-MI/FastSu… hub.docker.com/repository/doc…

After seven (7!) years of work with >20 researchers at 10 different institutions, we are super excited to release NextBrain, a next-gen probabilistic atlas of the human brain with 333 regions: github-pages.ucl.ac.uk/NextBrain Preprint, data, code, videos, and much more in this 🧵(1/5)
