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...

Wow!

Need cortical surface extraction which is time efficient while being more anatomically correct than classic pipelines? Try Qiang Ma's pipeline - tuned for neonatal (dHCP) but we are already using it for fetal and works on ya HCP arxiv.org/abs/2405.08783 github.com/m-qiang/dhcp...
