Involvement of the amygdala in memory storage: interaction with other brain systems.
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.
Retrieval of emotional memories.

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.
Memory for emotional events: differential effects of centrally versus peripherally acting β-blocking agents
The results support the view that memory of a mild emotional event involves activation of central, but not necessarily peripheral β-adrenergic receptors, while propranolol impaired memory in subjects who saw the emotional version of the slide show.
Amygdala-hippocampus dynamic interaction in relation to memory
A system, composed of the amygdala and the hippocampus, that acts synergistically to form long-term memories of significantly emotional events is described.
The effect of beta-adrenergic blockade after encoding on memory of an emotional event
This experiment does not support a role for noradrenaline in the post-encoding phase and on the later processes of consolidation and retrieval, and it remains possible that with a different dosage or timing protocol a post-treatment effect of noradRenaline in humans can be found.
beta-Adrenergic blockade and emotional memory in PTSD.
PTSD and control subjects did not differ in the acquisition and retention of memories under emotionally arousing or emotionally neutral conditions, nor were differential effects of propranolol observed between the two groups.
The biochemistry of memory formation and its regulation by hormones and neuromodulators
A key role in memory modulation of dopaminergic synapses, of brain benzodiazepine-like substances, and perhaps of serotonin acting at specific steps of the biochemistry of memory processes in the hippocampus, amygdala, or elsewhere is demonstrated.


Beta-adrenergic activation and memory for emotional events.
It is reported here that propranolol significantly impaired memory of the emotionally arousing story but did not affect memory ofThe emotionally neutral story, which supports the hypothesis that enhanced memory associated with emotional experiences involves activation of the beta-adrenergic system.
Stress and cognitive function
The possible contribution of the amygdala to memory.
The processing of episodic memories is believed to depend on the proper functioning of so-called bottleneck structures through which information apparently must pass in order to be stored long term.
Modulation of memory fields by dopamine Dl receptors in prefrontal cortex
The precision shown for D1 receptor modulation of mnemonic processing indicates a direct gating of selective excitatory synaptic inputs to prefrontal neurons during cognition.
Glucocorticoid-induced impairment in declarative memory performance in adult humans
Investigation of the cognitive consequences of DEX treatment in normal adult human subjects hypothesizing a decrease in declarative memory performance after extended but not overnight treatment found correct paragraph recall improved over the course of treatment, consistent with practice.
Modulation of memory processing by cholecystokinin: dependence on the vagus nerve.
Cholecystokinin-octapeptide (CCK-8), which is a gastrointestinal hormone released during feeding, enhances memory retention when administered intraperitoneally, and may mediate the memory-enhancing effects of feeding.
