Do you censor high motion frames in fMRI? In two preprints by @twktan.bsky.social @mandymejia.bsky.social, we find that we may be censoring too much!

Strict censoring leads to worse personalized TMS targets than no censoring, even with high motion!

Can brain training improve #meditation? 🧘♂️
New study by @saampras.bsky.social featuring AddPro's @vale-addiction.bsky.social suggests that #neurofeedback can boost awareness + reduce emotional distress during meditation in beginners!

AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements...

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! 🧠📊

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
Thanks, Elvisha!
⚠️ Note: This is an early **prototype**, built from HCP lifespan data. We’d love to hear your thoughts—try it out and let us know what you think!
🧠 What can you do?
✨ Get real-time reference thickness charts across the lifespan
✨ Query any location on the cerebral cortex
✨ See how cortical thickness varies over time at different loci
Here’s a sneak peek: 🎥👇
🚀 Explore Spectral Normative Modeling in action!
We’ve built an interactive visualization showcasing high-resolution normative reference ranges generated via SNM.
