TLDR
A simple model is described that unifies much of the data that previously were viewed as contradictory about the molecular mechanisms of this long-lasting increase in synaptic strength in the hippocampus.Abstract:
Long-term potentiation of synaptic transmission in the hippocampus is the leading experimental model for the synaptic changes that may underlie learning and memory. This review presents a current understanding of the molecular mechanisms of this long-lasting increase in synaptic strength and describes a simple model that unifies much of the data that previously were viewed as contradictory.read more

Mitochondria, synaptic plasticity, and schizophrenia.
TL;DR: It is proposed that mitochondrial dysfunction in schizophrenia could cause, or arise from, anomalies in processes of plasticity in this disorder.

TL;DR: In this article, the FG loop (FGL), a synthetic 15 amino acid peptide corresponding to the binding site of NCAM for the fibroblast growth factor receptor 1 (FGFR1), immediately after training rats in fear conditioning or water maze learning, induced a longlasting improvement of memory.

Systems and methods for reducing the likelihood of inducing collateral neural activity during neural stimulation threshold test procedures
TL;DR: In this article, a test procedure for determining a neural stimulation threshold of a patient is described. But the procedure is not defined in detail, and the procedure can be further extended to calculate a treatment stimulation signal directed toward affecting a neural activity within the patient.

Long-term potentiation of exogenous glutamate responses at single dendritic spines
TL;DR: Results demonstrate that activation of postsynaptic glutamate receptors by glutamate is not only necessary, but sufficient, for the induction of NMDAR-dependent long-term potentiation and reveal additional aspects of its expression.

A synaptic model of memory: long-term potentiation in the hippocampus
TL;DR: The best understood form of long-term potentiation is induced by the activation of the N-methyl-d-aspartate receptor complex, which allows electrical events at the postsynaptic membrane to be transduced into chemical signals which, in turn, are thought to activate both pre- and post Synaptic mechanisms to generate a persistent increase in synaptic strength.

Dendritic spine changes associated with hippocampal long-term synaptic plasticity
Florian Engert,Tobias Bonhoeffer +1 more
TL;DR: After induction of long-lasting (but not short-lasting) functional enhancement of synapses in area CA1, new spines appear on the postsynaptic dendrite, whereas in control regions on the same dendrites or in slices where long-term potentiation was blocked, no significant spine growth occurred.

TL;DR: W Whole cell recordings reveal that postsynaptic mechanisms, including N-methyl-D-aspartate (NMDA) receptor function, are intact and are therefore a suitable model for studying the relation between LTP and learning processes.
