Participants laid in an fMRI scanner, they were shown 96 pictures at random. Each picture was viewed for 2.88s, with 12.96s in between each. The participants would focus on a fixation cross. The fMRI machine collected information about the activity in the brain during the picture viewing.
When participants saw each picture, they would press one of four buttons with their right-hand

Extremely emotionally intense
Not emotionally intense
The participants returned to complete a recognition task. They viewed the same 96 pictures along with an additional 48 foils, matched to the original for valence arousal.Responses were rated 1 for forgotten, 2 for familiar 3 for remembered with certainty
Hence, there's a connection between amygdala activation emotional memory.Emotional experiences are better remembered!
Participants' ratings for emotional intensity reflected valence arousal ratings.Amygdala activation significantly correlated with higher ratings of emotions!
Left amygdala activity during encoding predicts subsequent memory. The degree which they can do that is a function of emotional intensity
