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! doi.org/10.64898/202... arxiv.org/html/2603.07... Strict censoring leads to worse personalized TMS targets than no censoring, even with high motion!

If we could record all neurons we still would not know how they communicate: medium.com/@kording/628...
Would recording all neurons reveal their interactions?
For years, I was captivated by the idea that if we could record the activity of every neuron in the brain, we’d eventually crack the code…

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)

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...
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

SPM goes Python for its 30 year anniversary! Great news for #neuroimaging! 👍
Happy 30th birthday year to SPM!! 🎈🍰 To get the party started, we are delighted to announce SPM 25.01, a major new version of the open-source neuroimaging software. Read the preprint to discover what's new arxiv.org/pdf/2501.12081 and download SPM for free from Github github.com/spm/spm/rele...
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. 🧵
