The roles of STP and LTP in synaptic encoding [PDF]

PeerJ, 2013
Long-term potentiation (LTP), a cellular model of learning and memory, is generally regarded as a unitary phenomenon that alters the strength of synaptic transmission by increasing the postsynaptic response to the release of a quantum of neurotransmitter.

Cardiac Arrest Induces Ischemic Long-Term Potentiation of Hippocampal CA1 Neurons That Occludes Physiological Long-Term Potentiation

Neural Plasticity, 2018
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.

The α1 subunit of the GABA(A) receptor modulates fear learning and plasticity in the lateral amygdala

Frontiers in Behavioral Neuroscience, 2009
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

Long-term potentiation: Peeling the onion [PDF]

Neuropharmacology, 2013
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.

Long Term Potentiation as a Mechanism for Learning and Memory [PDF]

Cell Journal, 2009
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

Temporal sensitivity of protein kinase a activation in late-phase long term potentiation. [PDF]

PLoS Computational Biology, 2010
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,

Effects of intra-dentate gyrus microinjection of myokine irisin on long-term potentiation in male rats [PDF]

Arquivos de Neuro-Psiquiatria, 2020
Induction of long-term potentiation (LTP) increases the storage capacity of synapses in the hippocampal dentate gyrus (DG). Irisin is a myokine generated from FNDC5 (a gene precursor) during exercise.

Erythropoietin enhances hippocampal long-term potentiation and memory

BMC Biology, 2008
Background Erythropoietin (EPO) improves cognition of human subjects in the clinical setting by as yet unknown mechanisms. We developed a mouse model of robust cognitive improvement by EPO to obtain the first clues of how EPO influences cognition, and ...

Age-dependent loss of PTP and LTP in the hippocampus of PrP-null mice

Neurobiology of Disease, 2003
We have investigated synaptic function in the hippocampus in mice of different ages carrying a null mutation in the PrP gene. Experiments carried out in vivo and in vitro in two laboratories revealed no differences in the ability of juvenile and young ...

Convergent evidence for abnormal striatal synaptic plasticity in dystonia

Neurobiology of Disease, 2010
Dystonia is a functionally disabling movement disorder characterized by abnormal movements and postures. Although substantial recent progress has been made in identifying genetic factors, the pathophysiology of the disease remains a mystery.
