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. 🧵

The limiting factor for MRI based prediction of behavioral traits may be neither the imaging nor the pipeline or learning algorith but rather the reliability of the target phenotypes Thought provoking work my Martin Gell et al: www.nature.com/articles/s41...

This is what happens if preprints are treated as „scientific literature“ Don’t get me wrong, I am all for preprinting. But unfortunately, it is often ignored that anybody can preprint anything

woo hoo - fantastic new work from ‪@wanb.bsky.social‬ @sofievalk.bsky.social @sbe.bsky.social & many more on microstructural asymmetry now out in Nature Comms ⤵️

Looked into BlueSky a while ago… really empty at that time X becoming useless for interesting reads and discussions on science send me in a social-media hiatus Back now and excited about things to come

Useful reminders from @sbe.bsky.social about #neuroimaging analysis #reproducibility at #OHBM2024: - Different atlases lead to different connectivity matrices. - The target massively matters. - ML algorithms just love shortcuts.

Lots to enjoy in this new paper by Sam Vickery @sbe.bsky.social and others. Brain areas in humans that show the greatest expansion from chimp -> human are the areas that are most susceptible to to the effects of aging www.science.org/doi/10.1126/...

Somehow it seems that computational models were immune to the current sample-size worries in #neuroimaging Turns out they are not 😱 DCM models and connections need 100+ subjects to give stable results New work by Alexander Silchenko & Felix Hoffstaedter: onlinelibrary.wiley.com/doi/10.1002/...

Fantastic but very worrisome work by Sami Hamdan: Confound removal in machine learning can itself lead to leakage -> After information about the target from the features using standard approaches you can STILL predict it well academic.oup.com/gigascience/... #neuroskyence #MLSky #neuroimaging

Finally out 🎉 - our meta-analysis of 403 neuroimaging studies on language (3/3) Quite some functional specialization in subcortical areas, too. This and many more details can be found here: psycnet.apa.org/fulltext/202... Paper is open access !!

Finally out 🎉 - our meta-analysis of 403 neuroimaging studies on language (2/3) We ended up discovering truly subdomain-specific brain areas in spite of substantial covergence Functional specialization was most pronounced in the cortex but we also found considerable cerebellar effects

Finally out 🎉 - our meta-analysis of 403 neuroimaging studies on language (1/3) In addition to providing robust evidence on the engagement of classical language regions during language tasks, we also investigated the processing of linguistic subdomains: semantics, syntax, phonology and pragmatics!

Just wondering, am I the only person living (and loving) inbox-zero for years? I use my inbox as a todo list and make extensive use of „defer / put back“. Works amazing and each time I am back to empty it feels rewarding

A main goal of our institute is to provide open software & resources - DataLad (data-management) - JTrack (mHealth / wearable suite) - JuLearn (user-friendly ML library) - ANIMA (meta-analyses results) - JuSpace (MRI-PET integration) - many more... Full catalogue: www.fz-juelich.de/en/inm/inm-7...

Pitching skeptical views on #neuroimaging and machine-learning at the rating-state Brain conference. That meeting fully reflected my split feelings at the moment. The conference was stimulating, meeting colleagues was fun and discussions exciting. But travel is simply annoying

So, let's share some science. 🤓 This is my latest preprint, first-authored by Natalia Chechko. We tracked temporal trajectories of resting brain-function in healthy mothers from 1 week to 6 months after childbirth. doi.org/10.1101/2023... #Neuroscience #MedSky #PsychSciSky #Neuroimaging 🧵1/n

Not sure, how many are here already to whom this would be of interest, but I‘ll try All others, please share 🙏🏽 We are currently considering to strengthen open (#neuroimaging) science in the German clinical societies like DGKN, DGPPN etc. Would you like to contribute / engage / help ?

What a tour de force on personality factors, brain health & #neuroskyence: www.nature.com/articles/s44... Includes relationship with multiple diseases, analysis of modulating factors and #neuroimaging Large sample and long follow-up. But why use items as proxies rather than actual Big-5 scores?
