1/11 Excited to share our @Naturestudy led by @leonooi.bsky.social @csabaorban.bsky.social @shaoshiz.bsky.social AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements... doi.org/10.1038/s415...

🧠 #OHBM2025 is fast approaching, with a stellar educational session from @ohbmossig.bsky.social & @ohbmenvironment.bsky.social‬ I'll be presenting a semi-hands-on course on reproducible research workflows, from code to visualization. 📖 Slides are now online: sina-mansour.github.io/ohbm2025-rep...

Can deep learning help us solve dynamical systems problems, particularly those used in neural mass models? Check out this preprint to read about the perks...

Join us Mon 3/10 for a roundtable discussion addressing best practices and emerging opportunities in human brain imaging and how they can advance the study of women’s brain health.

New paper‼️ Interested in the protective impacts of parenthood on brain dynamics? 👨‍👩‍👦‍👦🧠 Read Edwina Orchard & @sidchop.bsky.social's new paper, out now in PNAS @pnas.org ! With collaborators L. Ooi, P. Chen, L. An @bttyeo.bsky.social, and more! 🔗https://tinyurl.com/parentalbrain

Congrats to Winnie Orchard & @sidchop.bsky.social on their new #ParentalBrain paper, now out in PNAS! They find evidence for the neuroprotective effect of parenthood for women AND men! 👩‍🍼👨‍🍼🧠 It's lovely work, and I'm proud to have played a tiny role in it. Read it here 👇 #neuroskyence #neuroimaging

If we could record all neurons we still would not know how they communicate: medium.com/@kording/628...

Do you work on surface MRI such as HCP data? Our paper is finally out in Imaging Neuroscience, showing biases in surface fMRI. The revised ms has many new insights! TLDR: Vertices are much closer to each other in sulci, resulting in (fake) high spatial autocorrelation. (1/5)

Had a fantastic time presenting our novel eigenmode-driven normative models at the ISMRM Diffusion Workshop! 🧠📊 Check out our preprint here: www.medrxiv.org/content/10.1...

Great talk by Simona Schiavi at the ISMRM workshop on 40 years of diffusion! Interesting to see the DK atlas as the top choice for mapping connectomes—though, as expected, a diverse range of opinions. No single right answer! @ismrm.bsky.social

So much research focusses on using brain connectivity to predict an individual's cognition, IQ, disease status, etc. BUT what about the inverse problem? Can personal data be used to build an individual's whole connectome? YES - with AI: www.biorxiv.org/content/10.1...

Useful read to sharpen your "Defence against the dark charts" 🪄

Connectome architecture favours within-module diffusion and between-module routing. Really cool multi-species work from Caio Seguin on module-defined communication policies in connectomes! www.biorxiv.org/content/10.1...

Caio is having a good day. Another preprint on which he's first author -- this time, describing pathways through the connectome for indirectly stimulating subgenual cingulate cortex in the context of depression. Neuroanatomical pathways of TMS therapy for depression www.medrxiv.org/content/10.1...

TMS is delivered to the DLPFC in depression to modulate SGC activity But axons linking DLPFC and SGC are absent. How then does TMS stimulation delivered to the DLPFC modulate SGC activity? Check out Caio's work on how stimulation effects propagate in the absence of direct anatomical paths

🚀 Explore Spectral Normative Modeling in action! We’ve built an interactive visualization showcasing high-resolution normative reference ranges generated via SNM. 🔗 Try it here: sina-mansour.github.io/normative_br...

💥 special issue on open datasets: deadline extended 💥

1/ Excited to share our latest preprint! 🚀 We introduce Spectral Normative Modeling (SNM)—a novel approach leveraging graph spectral methods to advance brain charting towards personalized precision medicine. 🔗 www.medrxiv.org/content/10.1...

SPM goes Python for its 30 year anniversary! Great news for #neuroimaging! 👍

Thanks to everyone's feedback, we have updated our calculator to optimize sample size N & scan time T for fMRI studies: leonoqr.github.io/ORSP_Calcula... The first new feature is that users can explore how different N & T leads to different accuracy, e.g., N=1000 & T=30min => 81% max accuracy. 🧵

Just published🔈 "Structurally informed models of directed brain connectivity" Read: rdcu.be/d3dC4 We review how structural connectivity constrains directed connectivity models 🧠 Lead by @matthewdgreaves.bsky.social w/ @novelli-leo.bsky.social, @sinamansourl.bsky.social and Andrew Zalesky
