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… Expand
Emotional Memory Mechanisms in the Human Brain
Neurobiological accounts of emotional memo ry have been derived largely from animal models investi gating the encoding and retention of memories for events that signal threat. This literature hasExpand

TLDR
The amygdala interacts with cortical regions to mediate other aspects of emotional memory, including the encoding 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.

Retrieval of emotional memories.

TLDR
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. Expand
Enhanced Emotional Memory
Memory for emotional events is typically more vivid and accurate than memory for neutral ones. The modulation model focuses on the consolidation of memory traces to provide a partial account ofExpand
Emotional memory persists longer than event memory.
TLDR
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. Expand
Emerging Directions in Emotional Episodic Memory
TLDR
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. Expand
Emotion–Cognition Interactions
Limbic forebrain regions are anatomically positioned to integrate cortical and subcortical processing streams that mediate cognitive and emotional functions. Feedback projections to sensory corticesExpand
The slow forgetting of emotional episodic memories: an emotional binding account
TLDR
This work proposes that time-dependent effects of emotion can be better understood by an emotional binding account whereby the amygdala mediates the recollection of item-emotion bindings that are forgotten more slowly than item-context bindings supported by the hippocampus. Expand
Level of Processing Modulates the Neural Correlates of Emotional Memory Formation
TLDR
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. Expand
3.26 – Memory Modulation
This chapter reviews extensive evidence from both animal and human research indicating that stress hormones activated by emotional arousal modulate the consolidation of memory of recent experiences.Expand

TLDR
Across studies, the amygdala has been consistently implicated as playing a key role in enhancing explicit memory for both pleasant and unpleasant emotional stimuli through modulation of encoding and consolidation processes. Expand
Impaired declarative memory for emotional material following bilateral amygdala damage in humans.
TLDR
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. Expand
fMRI correlates of the episodic retrieval of emotional contexts
TLDR
Encoding of emotionally neutral pictures in association with positively, neutrally or negatively valenced background contexts led to differential modulation of neural activity elicited in a subsequent recognition memory test for these pictures, which discussed the findings in terms of current models of emotional memory retrieval. Expand
Emotional context modulates subsequent memory effect
TLDR
It is demonstrated that successful episodic encoding is differentially modulated by emotional context, which contributes to the understanding of the interaction of emotion and cognition and is of general relevance for studies of episodic memory. Expand
Encoding of emotional memories depends on amygdala and hippocampus and their interactions
TLDR
Data indicate a reciprocal dependence between amygdala and hippocampus during the encoding of emotional memories in patients with variable degrees of left hippocampal and amygdala pathology who performed a verbal encoding task during functional magnetic resonance imaging. Expand

TLDR
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. Expand

  • E. Phelps

TLDR
The amygdala and hippocampal complex, two medial temporal lobe structures, are linked to two independent memory systems, each with unique characteristic functions, which act in concert when emotion meets memory. Expand
Interaction between the Amygdala and the Medial Temporal Lobe Memory System Predicts Better Memory for Emotional Events
TLDR
Results provide direct evidence for the modulation hypothesis in humans and reveal a functional specialization within the MTL regarding the effects of emotion on memory formation. Expand
Dissociable Temporal Lobe Activations during Emotional Episodic Memory Retrieval
TLDR
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.
