Behavioural stress facilitates the induction of long-term depression in the hippocampus
It is reported that the induction of stable homosynaptic LTD in the CA1 area of the hippocampus of awake adult rats is facilitated, rather than inhibited, by exposure to mild naturalistic stress.
Antistress Effect of TRPV1 Channel on Synaptic Plasticity and Spatial Memory
Prenatal stress modifies hippocampal synaptic plasticity and spatial learning in young rat offspring
Prenatal stress alters synaptic plasticity and enhances the effects of acute stress on synaptic Plasticity in the hippocampus, which may be the mechanism for the impaired spatial learning and memory in young rat offspring.
Spatial exploration induces a persistent reversal of long-term potentiation in rat hippocampus
The discovery of a novelty-induced reversal of LTP expression provides strong evidence that extensive long-lasting decreases in synaptic efficacy may act in tandem with enhancements at selected synapses to allow the detection and storage of new information by the hippocampus.
Enriched environment experience overcomes the memory deficits and depressive-like behavior induced by early life stress
Chronic Morphine Treatment Impaired Hippocampal Long-Term Potentiation and Spatial Memory via Accumulation of Extracellular Adenosine Acting on Adenosine A1 Receptors
A potential mechanism by which chronic exposure to morphine leads to impairment of both hippocampal LTP and spatial memory is revealed.
The effect of acute stress on LTP and LTD induction in the hippocampal CA1 region of anesthetized rats at three different ages
Impaired contextual fear extinction and hippocampal synaptic plasticity in adult rats induced by prenatal morphine exposure
The results provide the first evidence suggesting that prenatal morphine exposure may increase vulnerability to fear memory‐related neuropsychiatric disorders in adulthood.
Exposure to chronic constant light impairs spatial memory and influences long-term depression in rats
Stress Enables Synaptic Depression in CA1 Synapses by Acute and Chronic Morphine: Possible Mechanisms for Corticosterone on Opiate Addiction
It is shown that hippocampal synaptic plasticity may play a significant role in the effects of stress or glucocorticoids on opiate addiction, and stress to enable LTD induction, but not the ability of stress in tandem with morphine to cause synaptic depression.
