In Alzheimer’s disease, routine clinical use of PET is limited by cost & accessibility. But can one predict PET composite values from more accessible data? A nice study elucidating promising & limiting aspects of using ML to predict tau-PET from plasma biomarkers & MRI. #dementia #alzsky

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...

Big shout out to Filip & Bratislav + co-authors for this very useful & important work! An example (@biofinder.bsky.social data) showing subjects' FC "strength" can to some degree explain pathological tau protein patterns better than group-FC but not their mere "degree". An excellent null model.

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 brain’s action-mode is created by a dedicated action-mode network (AMN) rdcu.be/d5odm. In the brain’s mode continuum, AMN sits opposite DMN’s default-mode, as yin-yang.

Wish we had polls here but in their absence: can ML people tell me how they would define "ablation" or "ablation study"? As someone who frequently translates between neuroscience and ML, I fear this is another term that we both use, but slightly differently. #MLsky

I am often invited to review papers on deep learning for medical images. Unfortunately many papers do the same mistake; they split data into training/validation/test on the slice/image/patch level instead of on the patient level. This will lead to inflated test scores, as images from the same
