BOLD–behavior correlation. Areas showing a significant interaction in how BOLD activity during source memory encoding relate to source memory performance in the two groups. A, Two clusters in the left hemisphere show a positive significant interaction (more positive slope in the short-delay group). B, Descriptive plotting of the relationships in the two groups. β values (parameter estimates) are extracted from the posterior cingulate cortex cluster. C, Significant correlations between source memory encoding parameter estimates and source memory performance in the short-delay group (left) and the long-delay group (right). D, Descriptive plotting of relationships between hippocampal BOLD activity during source memory encoding and source memory performance in the two groups. r values represent partial correlations, controlling for participant age and sex. LL, Left lateral surface; LM, left medial surface.
