Postencoding interactions between the VTA and CSC. We found experience-dependent increases in functional connectivity of the VTA (left) with both high-reward CSC and low-reward CSC (middle). However, interactions of VTA-high-reward CSC predicted high-reward associative memory, although no such relationship exists between VTA-low-reward CSC interactions and low-reward memories (right). Green dots indicate high-reward values. Gray dots indicates low-reward values. Solid lines indicate significant correlations. *p < 0.05. Hyphenated lines indicate nonsignificant correlations.
