Activation foci for famous versus unfamiliar name subtraction (Famous > Unfamiliar)^*

Region #	Region	Cortical Component Loadings	Hippocampal Component Loadings	x	y	z	Stable Group Volume	Declining Group Volume
1	Bilateral Posterior Cingulate Cortex, Precuneus	0.884	0.257	−0.9	−52.4	24.6	37.05
2	Left Angular Gyrus	0.889	0.266	−45.4	−55.9	23.7	26.14	1.44
3	Left Superior Frontal Gyrus	0.805	0.018	−17.8	29.5	41	30.84
4	Right Angular Gyrus	0.815	0.275	46.2	−59.6	27.1	18.68
6	Right Superior, Middle Frontal Gyrus	0.839	0.009	22.5	16.5	46.8	3.2
5	Left Parahippocampal Gyrus, Hippocampus	0.269	0.898	−21.9	−21	−10.7	2.29
7	Right Parahippocampal Gyrus, Hippocampus	0.053	0.946	23.9	−23.2	−11.6	0.86
8	Right Cerebellum (Crus 1)	0.425	0.268	11.3	−74.8	−21.9	1.03

Note: Critical value (2*r_{crit,p = .01}) used to identify significant component loadings was 0.560 [80].

^*PCA conducted on four negative activation (Unfamiliar > Familiar) clusters (Left Precentral Gyrus; Bilateral Supplementary Motor Area; Right Insula; Left Middle Occipital Gyrus) revealed one component that did not predict decline; this component was dropped from subsequent analyses.
