Default mode network connectivity in the PiB‐positive Down's syndrome group compared to the typically developing control group, showing (a) controls > PiB‐positive Down's syndrome, and (b) PiB‐negative Down's syndrome > controls. PiB +ve, PiB‐positive; prefixed to the abbreviation of a brain region, L and R indicate the left and right hemisphere, respectively. Furthermore, a suffix of 1 or 2 to an abbreviation serves to differentiate different significant clusters located within a single brain region. ACG, anterior cingulate gyrus; CER9, region 9 of the cerebellum; IFGtriang, inferior frontal gyrus pars triangularis; IOG, inferior occipital gyrus; IPL, inferior parietal lobule; ITG, inferior temporal gyrus; MTG, middle temporal gyrus; PCUN, precuneus; SFGmed, medial superior frontal gyrus; SMA, supplementary motor area; SPG, superior parietal gyrus [Color figure can be viewed at http://wileyonlinelibrary.com]
