Emotion and remembering

Sharot, Delgado, and Phelps. Nat. Neurosci. 2004 (no ref yet: e-pub)

How emotion enhances the feeling of remembering. From the abstract:

"We measured brain activity associated with the feeling of remembering emotional and neutral photos. Subjects indicated whether recognition was accompanied by a recollection of details about the study episode ('remember') or not ('know')....In contrast, 'remember' judgments for emotional photos were associated with enhanced activity in the amygdala, suggesting that subjects rely on arousal and perceptual fluency to evaluate these memories."
