Naloxone and β-endorphin alter the effects of post-training epinephrine on memory
TLDR
It is found that a novel experience given 1 h prior to training blocked the memory-impairing effect of post-training Epi otherwise obtained in both tasks, indicating that theMemory-enhancing and memory-Impairing effects of Epi are mediated by different mechanisms.
Involvement of basolateral amygdala alpha2-adrenoceptors in modulating consolidation of inhibitory avoidance memory.
TLDR
Results provide additional evidence that consolidation of inhibitory avoidance memory depends critically on prolonged activation of the noradrenergic system in the BLA and indicate that this modulatory influence is mediated, in part, by pre-synaptic alpha(2)-adrenoceptors.
Noradrenergic Receptor Blockade of the NTS Attenuates the Mnemonic Effects of Epinephrine in an Appetitive Light–Dark Discrimination Learning Task
TLDR
Findings indicate an involvement of NTS noradrenergic neurons in mediating the effects of peripheral epinephrine on memory storage processes.
Basolateral amygdala noradrenergic influence enables enhancement of memory consolidation induced by hippocampal glucocorticoid receptor activation.
TLDR
It is found that bilateral excitotoxic lesions of the basolateral nucleus of the amygdala (BLA) block the enhancing effects of posttraining systemic or intrahippocampal glucocorticoid administration on memory for inhibitory avoidance training, which is consistent with the hypothesis that the BLA regulates the strength of memory consolidation in other brain structures.
Intra-amygdala injections of corticotropin releasing factor facilitate inhibitory avoidance learning and reduce exploratory behavior in rats
TLDR
Results suggest that the amygdala is one of the anatomical loci involved in CRF modulation of memory processing and exploration in rats, and in mediating the influences of stress on behavior.

The noradrenergic system of the amygdala and aversive information processing.
TLDR
The results suggest that the noradrenergic system of the amygdala is involved in the long-term processing of the emotional attributes of aversive information.
