Emotional events often attain a privileged status in memory. Cognitive neuroscientists have begun to elucidate the psychological and neural mechanisms underlying emotional retention advantages in the human brain. The amygdala is a brain structure that directly mediates aspects of emotional learning and facilitates memory operations in other regions, including the hippocampus and prefrontal cortex. Emotion–memory interactions occur at various stages of information processing, from the initial… 

Emotional Memory Mechanisms in the Human Brain

The amygdala interacts with cortical regions to mediate other aspects of emotional memory, including the coding and consolidation of pleasant and unpleasant arousing events into long-term memory, the narrowing of focus on central emotional information, the retrieval of prior emotional events and contexts, and the subjective experience of recollection and emotional intensity during retrieval.

The review of the literature addressing the effects of emotion on retrieval suggests that the amygdala, in combination with the hippocampus and prefrontal cortex, plays an important role in the retrieval of memories for emotional events.

Enhanced Emotional Memory

Mediation theory can complement the modulation model and together they may provide a more comprehensive account of human emotional memory, which is typically more vivid and accurate than memory for neutral ones.

Emerging Directions in Emotional Episodic Memory

Emerging evidence from brain imaging investigations demonstrates that emotion- and memory-related medial temporal lobe brain regions (amygdala and hippocampus, respectively), together with prefrontal cortical regions, play a pivotal role during both encoding and retrieval of emotional episodic memories.

Emotional memory persists longer than event memory.

It is found that the recognition performance for event memory differs from that for emotional memory, and although event recognition deteriorated equally for episodes that were or were not emotionally salient, emotional recognition remained high for only stimuli related to emotional episodes.

Level of Processing Modulates the Neural Correlates of Emotional Memory Formation

Two distinct activation patterns underlying emotional memory formation are suggested: an amygdala component that promotes memory during shallow encoding, especially for negative information, and a prefrontal component that provides extra benefits during deep encoding,especially for positive information.

Impaired declarative memory for emotional material following bilateral amygdala damage in humans.

The data support the hypothesis that the human amygdala normally enhances acquisition of declarative knowledge regarding emotionally arousing stimuli and that nondeclarative emotional memory in humans is impaired by lesions of the amygdala.

A group difference in the effect of arousal on the rate of forgetting suggests that the role of medial temporal lobe structures in memory consolidation for arousing events is conserved across species.

Using functional MRI and behavioral studies, it is found that distinct cognitive and neural processes contribute to emotional memory enhancement for arousing information versus valenced, nonarousing information.

Dissociable Temporal Lobe Activations during Emotional Episodic Memory Retrieval

Compared patterns of brain activation associated with retrieving previously studied emotional and neutral pictorial material suggest distinct functional roles for temporal lobe regions during emotional memory retrieval involving context-related tonic anterior temporal pole activation and a phasic item-related amygdala response.

The role of the amygdala and the medial temporal lobe memory regions in recollection and familiarity of emotional memory after lengthy retention intervals is clarified.

Amygdala activity related to enhanced memory for pleasant and aversive stimuli

It is shown that bilateral amygdala activity during memory encoding is correlated with enhanced episodic recognition memory for both pleasant and aversive visual stimuli relative to neutral stimuli, and that this relationship is specific to emotional stimuli.

A critical period for the impact of amygdala damage on the emotional enhancement of memory?

Evidence that unilateral lesions of the human amygdala arising early in development, but not in adulthood, are associated with a loss of the expected superior retrieval of emotionally arousing over neutral material adds to evidence for an early critical period in the development of amygdala function.
