Long-lasting potentiation and other forms of synaptic plasticity (including long-term depression, the counterpart of long-lasting potentiation) can be impaired by certain patterns of developmental ethanol exposure, and this also could be a consequence of persistent alterations in NMDA receptor levels and...
long-term potentiation(redirected from Long-lasting potentiation)Also found in: Dictionary, Encyclopedia. long-term potentiation n. Repeated presynaptic stimulation of a nerve, either naturally or in vitro, that results in the long-lasting increased strength of a synapse and is thought to be ...
Long-lasting potentiation is produced by a single application of 1.0 μM isoproterenol (a β-adrenergic antagonist) to the dentate gyrus. The results of the present work indicate that a much lower 75 nM concentration of isoproterenol produces long-lasting potentiation in the dentate gyrus if it ...

In this study, we found that potentiation of synaptic signaling at the electrical synapse onto LG can also be induced when the synapse was activated with subthreshold repetitive pulses or with a few strong suprathreshold shocks. LG LTP was induced in the preparation which had received pulses at ...
NE potentiated the population spike by 20–400%, whereas the population EPSP was rarely increased. At 39% of the potentiated sites NE application resulted in long-lasting potentiation (LLP) suggesting a role for NE in long-term hippocampal plasticity.关键词:...
A challenge dose of nicotine (0.4 mg kg−1 s.c.) produced a long-lasting potentiation (LLP) of field EPSPs evoked in the dentate gyrus by stimulation of the medial perforant path of urethane-anaesthetized rats primed four weeks previously with seven daily injections of nicotine (0.8 mg kg...
Wild-typea-synuclein, a protein of unknown function, has received much attention because of its involvement in a series of diseases that are known as synucleinopathies. We find that long-lasting potentiation of synaptic transmission between cultured hippocampal neurons is accompanied by an...
Whereas the monomethylation of hippocampal phosphatidylethanolamine is decreased following the induction of long-lasting potentiation of the CA1 population spike, carboxymethylation of proteins is unaffected.
