Joey A. Contreras,Joaquín Goñi,Shannon L. Risacher,Enrico Amico,Karmen K. Yoder,Mario Dzemidzic,John D. West,Brenna C. McDonald,Martin R. Farlow,Olaf Sporns,Andrew J. Saykin +10 more
TL;DR: Resting‐state functional magnetic resonance imaging (rsfMRI), combined with brain connectomics, is investigated to assess changes in whole‐brain functional connectivity (FC) in relation to neurocognitive variables.
Journal ArticleDOI
