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
- Reposted by Sina Mansour L.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...

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.

- Reposted by Sina Mansour L.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

- 2/ 🧠 Brain charts are like growth charts in pediatrics—they establish reference norms for brain structure, helping the detection of abnormal alterations in individuals, with implications for neurological & psychiatric disorders. Yet, current methods have limitations… ⚠️
- 3/ ⚠️ Brain charts are often limited to coarse whole-brain or regional phenotypes tied to a specific atlas. High-res charting is limited by computational constraints and data quality concerns. But what if we could model norms at any resolution, any atlas, all at once? 🤔✨
