Stronger functional connectivity within and between default mode and SNs supports better memory in older adults. Scatterplots illustrate the correlation in the entire older adult group between intrinsic functional connectivity (top row: within DMN; middle row: within SN; bottom row: between DMN and SN) and memory performance (left column: CVLT recall for assessing criterion validity; central column: item recognition for assessing construct validity). Superagers are indicated by hollow points. The brain maps (right column) highlight the hypothesized networks of interest (DMN in yellow and SN in blue), seed and target nodes (in orange), and the direction of correlation representing functional connectivity (direct/positive in red and inverse/negative in light blue). Recall memory was scored out of a total of 16. Network seeds were R PCC (Vincent et al. 2008) and R dAI (Touroutoglou et al. 2012). Displayed P values are uncorrected.
