People who showed more replay of high - reward memories showed better retention of these events during the post-scan test, as well as increased interactions between the hippocampus, a structure deep in the brain heavily involved in memory, and an area called the substantia nigra / ventral tegmental area complex, which is involved in reward processing, suggesting that reward played a role in stimulating the hippocampus after learning.
