WebFor the fMRI analysis, we grouped the 20 blocks into five imaging runs, each containing 96 trials and 48 fixations, with an interscan interval (TR) of 2 sec. The scanning apparatus and methods for both functional and anatomical data acquisition were identical to those we have published elsewhere ( Greene et al. 2006 ). WebFunctional connectivity estimated from functional MRI (fMRI) was the primary methodology in all studies. In addition, Wang et al. utilized a PET marker for Amyloid-β (Aβ) to assess the Alzheimer's endophenotype in terms of resting-state functional connectivity patterns differentiated between Aβ+ and Aβ- individuals. small head rottweiler
