Note: fisher transformed z(r) correlation coefficients between the initial PCCrsp seed and derived seeds (PCC, PHG, MTG. MFG. FMC) from age group contrast. PCC/rsp=initial posterior cingulate/retrosplenial seed; FMC=Frontal medial cortex; MTG=middle temporal gyrus; PCC=posterior cingulate cortex; PHG=parahippocampal gyrus. Age group comparisons are shown below the diagonal, and associations with fitness in the elderly are shown above the diagonal;

^*p<.05;

^**p<.003 (bonferroni corrected p-value for 15 correlations).
