Ischemic long-term potentiation (iLTP) is a form of synaptic plasticity that occurs in acute brain slices following oxygen-glucose deprivation. In vitro, iLTP can occlude physiological LTP (pLTP) through saturation of plasticity mechanisms.

Synaptic plasticity in the amydgala is essential for emotional learning. Fear conditioning, for example, depends on changes in excitatory transmission that occur following NMDA receptor activation and AMPA receptor modification in this region. The role

Ovarian Hormones, Aging and Stress on Hippocampal Synaptic Plasticity [PDF]
The ovarian steroid hormones estradiol and progesterone regulate a wide variety of non-reproductive functions in the central nervous system by interacting with molecular and cellular processes.

Long-term potentiation: Peeling the onion [PDF]
Since the discovery of long-term potentiation (LTP), thousands of papers have been published on this phenomenon. With this massive amount of information, it is often difficult, especially for someone not directly involved in the field, not to be overwhelmed.

State based model of long-term potentiation and synaptic tagging and capture [PDF]
Recent data indicate that plasticity protocols have not only synapse-specific but also more widespread effects. In particular, in synaptic tagging and capture (STC), tagged synapses can capture plasticity-related proteins, synthesized in response to ...

Long Term Potentiation as a Mechanism for Learning and Memory [PDF]
Since the 1970s when long term potentiation (LTP) was introduced to the scientific world;several studies have been devoted to determining whether this phenomenon is naturally abasic mechanism of learning and memory in mammalian brains. However, plenty of

Dendritic spines form the postsynaptic compartment of most excitatory synapses in the vertebrate brain. Morphological changes of dendritic spines contribute to major forms of synaptic plasticity such as long-term potentiation (LTP) or depression (LTD ...

Temporal sensitivity of protein kinase a activation in late-phase long term potentiation. [PDF]
Protein kinases play critical roles in learning and memory and in long term potentiation (LTP), a form of synaptic plasticity. The induction of late-phase LTP (L-LTP) in the CA1 region of the hippocampus requires several kinases, including CaMKII and PKA,

Long-term potentiation in frontal cortex: Role of NMDA-modulated polysynaptic excitatory pathways [PDF]
The present study examined the role of N-methyl-D-aspartic acid (NMDA) receptors in synaptic plasticity in regular-spiking cells of rat frontal cortex. Intracortical stimulation, at levels subthreshold for elicitation of action potentials, evoked a late ...

Synfire chains are thought to underlie precisely-timed sequences of spikes observed in various brain regions and across species. How they are formed is not understood. Here we analyze self-organization of synfire chains through the spike-timing dependent
