Stress, memory and the amygdala
B Roozendaal, BS McEwen, S Chattarji - Nature Reviews …, 2009 - nature.com
Emotionally significant experiences tend to be well remembered, and the amygdala has a
pivotal role in this process. But the efficient encoding of emotional memories can become …

Recovery after chronic stress fails to reverse amygdaloid neuronal hypertrophy and enhanced anxiety-like behavior
The hippocampus and amygdala are important components of the neural circuitry mediating
stress responses. While structural plasticity in the hippocampus may mediate cognitive …

The amygdala: contributions to fear and stress
JE LeDoux - Seminars in Neuroscience, 1994 - Elsevier
Recent studies have identified major components of the neural system mediating the
classical conditioning of defense or fear responses to sensory stimuli. The pathways involve …

Stress enhances fear by forming new synapses with greater capacity for long-term potentiation in the amygdala
Prolonged and severe stress leads to cognitive deficits, but facilitates emotional behaviour.
Little is known about the synaptic basis for this contrast. Here, we report that in rats …

Amygdala modulation of memory-related processes in the hippocampus: potential relevance to PTSD
A key assumption in the study of stress-induced cognitive and neurobiological modifications
is that alterations in hippocampal functioning after stress are due to an excessive activity …

Chronic stress causes amygdala hyperexcitability in rodents
JA Rosenkranz, ER Venheim, M Padival - Biological psychiatry, 2010 - Elsevier
BACKGROUND: Chronic stress is a major health concern, often leading to depression,
anxiety, or when severe enough, posttraumatic stress disorder. While many studies …

Human vulnerability to stress depends on amygdala's predisposition and hippocampal plasticity
R Admon, G Lubin, O Stern… - Proceedings of the …, 2009 - National Acad Sciences
Variations in people's vulnerability to stressful life events may rise from a predated neural
sensitivity as well as from differential neural modifications in response to the event. Because …

How the amygdala affects emotional memory by altering brain network properties
The amygdala has long been known to play a key role in supporting memory for emotionally
arousing experiences. For example, classical fear conditioning depends on neural plasticity …

From specificity to sensitivity: how acute stress affects amygdala processing of biologically salient stimuli
BACKGROUND: A vital component of an organism's response to acute stress is a surge in
vigilance that serves to optimize the detection and assessment of threats to its homeostasis …
