Case studies of patients with bilateral amygdala damage and functional imaging studies of normal individuals have demonstrated that the amygdala plays a critical role in encoding emotionally arousing stimuli into long-term declarative memory. However, several issues remain poorly understood: the separate roles of left and right amygdala, the time course over which the amygdala participates in memory consolidation, and the type of knowledge structures it helps consolidate. We investigated these… 

Figures and Tables from this paper

Verbal and nonverbal emotional memory following unilateral amygdala damage.
TLDR
The group with right amygdala damage showed the normal pattern of facilitation of memory by emotion for both verbal and nonverbal stimuli despite an overall reduction in memory performance, which offers partial support for a lateralized and material-specific pattern of the amygdala's contribution to emotional memory.
Emotional memory and perception in temporal lobectomy patients with amygdala damage
TLDR
Bilateral amygdala damage is particularly disruptive of emotional memory processes in comparison with unilateral temporal lobectomy, and the pattern of results implies that perception of emotional expressions and emotional memory are supported by separate processing systems or streams.
Memory for emotional material in temporal lobe epilepsy
The amygdala's role in long-term declarative memory for gist and detail.
TLDR
Preliminary support is provided for the idea that the amygdala may help filter the encoding of relevant information from stimuli that signal threat or danger in long-term declarative memory for those stimuli.
The effect of anticipation and the specificity of sex differences for amygdala and hippocampus function in emotional memory
TLDR
It is found that previously reported sex differences of memory associations with left amygdala for women and with right amygdala for men were confined to the ventral amygdala during picture viewing and delayed memory, and neuroanatomical evidence of sex differences for emotional memory is extended.
Verbal emotional memory in a case with left amygdala damage
TLDR
Results showed emotional encoding impairments and, after encoding was controlled for, emotional long-term consolidation, and suggest that separate cerebral networks support the processing of emotional versus neutral stimuli.
Distinct neural systems underlying reduced emotional enhancement for positive and negative stimuli in early Alzheimer's disease
TLDR
The results indicate that emotional memory impairments in AD may be underpinned by damage to regions implicated in emotional processing as well as frontoparietal regions, which may exert their influence via autobiographical memories and organizational strategies.
MRI studies of successful emotional memory encoding : A quantitative eta-analysis ishnu
TLDR
A meta-analytic approach is employed using activation likelihood estimates to assess the anatomical specificity and reliability of event-related fMRI activations related to successful memory encoding for emotional versus neutral information and proposes that the amygdala interacts with these structures to promote enhancements in perceptual processing, semantic elaboration, and attention.

Specifying the Contributions of the Human Amygdala to Emotional Memory: A Case Study
TLDR
The amygdala does not seem to be involved when episodic memory performance benefits from the valence of the stimuli, and the effects of amygdala damage to be limited to memory tasks affected by the neuromodulatory changes that occur with arousal.
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.
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.
Memory for Emotional Words Following Unilateral Temporal Lobectomy
TLDR
The results suggest that the deficit seen in emotional memory following unilateral temporal lobectomy is not a global deficit and may be limited to specific circumstances where emotion influences memory performance.
Arousal-Mediated Memory Consolidation: Role of the Medial Temporal Lobe in Humans
TLDR
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.
Functional MRI reveals left amygdala activation during emotion
Involvement of the amygdala in memory storage: interaction with other brain systems.
TLDR
Findings provide strong evidence supporting the hypothesis that the amygdala is involved in modulating long-term memory storage, as well as supporting the central hypothesis guiding the research reviewed in this paper.
The Effect of Emotional Content on Visual Recognition Memory: A PET Activation Study
TLDR
It is found that emotionally salient stimuli appeared to enhance processing of early sensory input during visual recognition, and neuroanatomical systems for emotion augmenting memory were not identified.
Conscious and unconscious emotional learning in the human amygdala
TLDR
The results indicate that the human amygdala can discriminate between stimuli solely on the basis of their acquired behavioural significance, and second, this response is lateralized according to the subjects' level of awareness of the stimuli.
