A. Regression plot demonstrating significant correlation between PiB DVR values and fMRI activity extracted from the precuneus/posterior cingulate ROI (R= .46; p=0.006). B. Bar graph showing the fMRI response in ROI from divided by CDR and PiB status, demonstrating a main effect of PiB but not of CDR status. PiB+ CDR 0 subjects demonstrated significantly higher fMRI activity than PiB- CDR 0 subjects (p=0.003). C. Bar graph of fMRI response extracted from control region in the calcarine cortex did not reveal any relationship with PPC amyloid levels.
