A) areas with robust negative loadings (i.e., concomitant decreased flow in AD relative to HC) as ascertained by the bootstrap procedure. Most areas are located around the Parahippocampal Gyrus in the Medial Temporal and Occipital Lobes; Thalamus was identified by our analysis as well. No areas of positive loadings (i.e., concomitant increased flow for AD subjects) were found. B) Subject expression of the discriminant pattern for both AD and HC groups. One can appreciate the very small overlap between the two groups.
