This pilot study provides initial support for further investigation into exercise augmented exposure therapy and shows that the PE+E group showed a greater improvement in PTSD symptoms and elevated BDNF relative to the PE only condition.

It is shown that amygdala modulation of Arc protein and synaptic plasticity in efferent brain regions occurs at a posttranscriptional level, and infusions of Arc antisense oligodeoxynucleotides into the dorsal hippocampus impaired performance of an inhibitory avoidance task, indicating that the changes in Arc protein expression are related to the observed changes in memory performance.

Findings indicate that glucocorticoid effects on memory consolidation depend on bidirectional interactions between the BLA and the medial prefrontal cortex, a brain region involved in higher-order cognitive and affective processing.

The findings suggest further that this memory‐modulatory system may be involved in the formation of traumatic memories and posttraumatic stress disorder in human subjects.

Evidence from several experiments indicates that activation of the basolateral amygdala plays an essential role in modulating memory consolidation processes involving other brain regions, providing strong support for the hypothesis that the BLA plays a critical role in regulating the consolidation of lasting memories of significant experiences.

Findings indicate that modulation of memory consolidation induced by cholinergic influences within the BLA requires activation of both m1 and m2 receptor synapses.

The degree of activation of the noradrenergic system within the amygdala in response to a novel, emotionally arousing experience predicts the extent of long‐term memory for that experience.

The present findings suggest that VNS promotes plasticity in the IL-BLA pathway to facilitate extinction of conditioned fear responses (CFRs) in rats.
