The stressed hippocampus, synaptic plasticity and lost memories
An overview of the neurobiology of stress–memory interactions is provided, and a neural–endocrine model is presented to explain how stress modifies hippocampal functioning.
Amygdala Is Critical for Stress-Induced Modulation of Hippocampal Long-Term Potentiation and Learning
It is indicated that an intact amygdala is necessary for the expression of the modulatory effects of stress on hippocampal LTP and memory.

Amygdalar NMDA Receptors are Critical for New Fear Learning in Previously Fear-Conditioned Rats
Results indicate that NMDA receptors in the BLA are crucial for the encoding of new fear memories, the formation of specific conditioned stimulus–unconditioned stimulus association, the expression of conditioned fear responses, and the extinction of acquired fear.
This paper presents a basic overview of neuroanatomy and explains how brain activity is measured, and surveys findings from the neuroeconomics literature on acquiring rewards and avoiding losses, learning, choice under risk and ambiguity, delay of gratification, and the role of emotions in decision-making.
Effects of stress and hippocampal NMDA receptor antagonism on recognition memory in rats.
Results suggest that stress and intrahippocampal administration of APV affect recognition memory by influencing synaptic plasticity in the hippocampus, as tested on the visual paired comparison task in rats.
Social Transmission of Fear in Rats: The Role of 22-kHz Ultrasonic Distress Vocalization
It is indicated that prior experience of fear and intact auditory system are required for receiver rats to respond to their conspecifics' conditioned fear responses and that learning plays a crucial role in the development of social signaling of danger by USVs.
Differential Effects of Cerebellar, Amygdalar, and Hippocampal Lesions on Classical Eyeblink Conditioning in Rats
The results suggest that, even during a simple delay eyeblink conditioning, animals learn about different aspects associated with the behavioral task that are subserved by multiple brain-memory systems that interact to produce the overall behavior.
