This research explored how the inherent stimulus properties and amount of devoted attention influenced the emotional enhancement of memory (EEM) effect on recollection and evaluated the correlations between emotional memory/EEM and the spontaneous brain activity of hippocampus, perirhinal, and entorhinal cortex, and the correlations between emotional memory/EEM and the topological properties of three stipulated emotional memory processing networks in 59 young adults using resting-state fMRI. The EEM was elicited by incidental encoding, negative images, and positive high-arousal images. The hippocampus, perirhinal, and entorhinal cortex play distinct roles in the recollection and familiarity processes of emotional memory and the EEM effect.
