LTP and LTD An Embarrassment of Riches
This work reviews those forms of LTP and LTD for which mechanisms have been most firmly established and examples are provided that show how these mechanisms can contribute to experience-dependent modifications of brain function.

The data suggest that synaptic depression can be triggered by prolonged NMDA receptor activation that is below the threshold for inducing synaptic potentiation, and it is proposed that this mechanism is important for the modifications of hippocampal response properties that underlie some forms of learning and memory.
The mGluR theory of fragile X mental retardation
Loss of fragile X mental retardation protein (FMRP), the defect responsible for fragile X syndrome in humans, increases LTD in mouse hippocampus, consistent with the growing evidence that FMRP normally functions as a repressor of translation of specific mRNAs.
Regulation of distinct AMPA receptor phosphorylation sites during bidirectional synaptic plasticity
It is shown that LTP and LTD reversibly modify the phosphorylation of the AMPA receptor GluR1 subunit, and that identical stimulation conditions recruit different signal-transduction pathways depending on synaptic history.
Altered synaptic plasticity in a mouse model of fragile X mental retardation
It is shown that a form of protein synthesis-dependent synaptic plasticity, long-term depression triggered by activation of metabotropic glutamate receptors, is selectively enhanced in the hippocampus of mutant mice lacking FMRP.
Neuroscience: Exploring the Brain
Acclaimed for its clear, friendly style, excellent illustrations, leading author team, and compelling theme of exploration, Neuroscience: Exploring the Brain, 4e takes a fresh, contemporary approach
Role for rapid dendritic protein synthesis in hippocampal mGluR-dependent long-term depression.
Local postsynaptic protein synthesis, triggered by synaptic activation of metabotropic glutamate receptors, was found to modify synaptic transmission within minutes.
Learning Induces Long-Term Potentiation in the Hippocampus
It is found that one-trial inhibitory avoidance learning in rats produced the same changes in hippocampal glutamate receptors as induction of LTP with HFS and caused a spatially restricted increase in the amplitude of evoked synaptic transmission in CA1 in vivo.
BDNF Regulates the Maturation of Inhibition and the Critical Period of Plasticity in Mouse Visual Cortex
It is proposed that BDNF promotes the maturation of cortical inhibition during early postnatal life, thereby regulating the critical period for visual cortical plasticity.
Ubiquitination Regulates PSD-95 Degradation and AMPA Receptor Surface Expression
It is shown that PSD-95 is regulated by the ubiquitin-proteasome pathway, and data suggest that ubiquitination of PSd-95 through an Mdm2-mediated pathway is critical in regulating AMPA receptor surface expression during synaptic plasticity.
