Journal ArticleDOI
The Temporal Dynamics Model of Emotional Memory Processing: A Synthesis on the Neurobiological Basis of Stress-Induced Amnesia, Flashbulb and Traumatic Memories, and the Yerkes-Dodson Law
TL;DR: It is proposed that with the onset of strong emotionality, the hippocampus rapidly shifts from a “configural/cognitive map” mode to a ‘flashbulb memory’ mode, which underlies the long-lasting, but fragmented, nature of traumatic memories.
Journal ArticleDOI
Exposing rats to a predator impairs spatial working memory in the radial arm water maze
TL;DR: The findings indicate that the capacity for stress to impair memory is influenced not only by the brain memory system involved in solving the task (hippocampal versus nonhipp hippocampus), but also by the difficulty of the task.
Journal ArticleDOI
Influence of predator stress on the consolidation versus retrieval of long-term spatial memory and hippocampal spinogenesis.
David M. Diamond,Adam M. Campbell,Collin R. Park,James C. Woodson,Cheryl D. Conrad,Adam D. Bachstetter,Ronald F. Mervis +6 more
TL;DR: Evidence of structural plasticity in dendrites of CA1 neurons which may be involved in the consolidation process, and how spinogenesis and memory are modulated by stress is provided.
Journal ArticleDOI
Acute predator stress impairs the consolidation and retrieval of hippocampus-dependent memory in male and female rats
Collin R. Park,Phillip R. Zoladz,Phillip R. Zoladz,Cheryl D. Conrad,Monika Fleshner,David M. Diamond,David M. Diamond +6 more
TL;DR: Overall, it is found that an intense, ethologically relevant stressor produced a largely equivalent impairment of memory in male and female rats, and sex-independent corticosterone-memory correlations, which may provide insight into commonalities in how traumatic stress affects the brain and memory in men and women.
Journal ArticleDOI
Chronic psychosocial stress impairs learning and memory and increases sensitivity to yohimbine in adult rats.
TL;DR: Stressed rats displayed impaired habituation to a novel environment, heightened anxiety, and increased sensitivity to yohimbine, an alpha(2) adrenergic receptor antagonist, which may yield insight into the basis of cognitive and neuroendocrine disturbances that commonly occur in people with anxiety disorders.
