Abstract: Emotional memory has been extensively investigated using functional neuroimaging techniques. These studies extend the understanding of the neural mechanisms of emotional memory, which were assessed mainly in animals. The authors reviewed recent studies of encoding and retrieval processes of emotional memory. These studies show evidence that the amygdala participates in emotional memory not only in the stage of consolidation, but also in the early stage of encoding, and the stage of retrieval. The correlation and connectivity analysis showed evidence for the interaction between the amygdala and the medial temporal lobe (MTL) in both encoding and retrieval stages. Recent studies suggest that stimulus category is also involved in modulation of emotional memory. The amygdala is involved in the processing of stimulus category, vividness and feeling of remembering for emotional memory. It is necessary to combine different types of techniques to explore the neural mechanisms of emotional memory in future.
