Enhanced human memory consolidation with post-learning stress: interaction with the degree of arousal at encoding.
TLDR
Cold pressor stress, which significantly elevated salivary cortisol levels, enhanced memory for emotionally arousing slides compared with the controls, but did not affect memory for relatively neutral slides, which further support the view that post-learning stress hormone-related activity interacts with arousal at initial encoding to modulate memory consolidation.
Glucocorticoid effects on object recognition memory require training-associated emotional arousal.
TLDR
The present findings suggest that training-induced emotional arousal may be essential for glucocorticoid effects on object recognition memory.
Sleep and cortisol interact to support memory consolidation.
TLDR
It is suggested that elevated cortisol may "tag" attended information as important to remember at the time of encoding, thus enabling sleep-based processes to optimally consolidate salient information in a selective manner and leads to a refinement of the neural processes recruited for successful retrieval of negative stimuli.

Making Memories Matter
This article reviews some of the neuroendocrine bases by which emotional events regulate brain mechanisms of learning and memory. In laboratory rodents, there is extensive evidence that epinephrine
Effects of emotional arousal on multiple memory systems: evidence from declarative and procedural learning.
TLDR
A picture recognition and a weather prediction task (WP) task (a probabilistic classification learning task) is utilized, which have been shown to rely on hippocampal- and striatum-based memory systems, respectively, to suggest a potential dissociation between how readily emotional arousal influences hippocampus-dependent and Striatum-dependent memory systems in humans.

Relationship of enhanced norepinephrine activity during memory consolidation to enhanced long-term memory in humans.
TLDR
Findings strengthen support for the hypothesis that enhanced memory for emotionally arousing events in humans depends critically on postlearning adrenergic modulation.
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.
Arousal-Induced Modulation of Memory Storage Processes in Humans
TLDR
The results demonstrate that arousal can modulate memory consolidation when induced shortly after learning and that an initial priming event may affect the response to subsequent similar arousing events.

Effect of amphetamine on long-term retention of verbal material
TLDR
It is shown that improved recall cannot be explained solely by general arousal or attentional processes, but must be due to consolidation, and that the memory enhancement applies to recall as well as to recognition.

Sex-Related Difference in Amygdala Activity during Emotionally Influenced Memory Storage
TLDR
Results demonstrate a clear gender-related lateralization of amygdala involvement in emotionally influenced memory, and indicate that theories of the neurobiology of emotionally influencing memory must begin to account for the influence of gender.
