Induction of LTP in the human auditory cortex by sensory stimulation
European Journal of Neuroscience, 2005AbstractHigh‐frequency, repetitive, auditory stimulation was used to determine whether induction of a long‐lasting increase of the human auditory evoked potential (AEP) was possible. Recording non‐invasively with electroencephalogram scalp electrodes, stable increases in amplitude were observed in the N1 component of the AEP, which is thought to ...

Contributions of Quisqualate and NMDA Receptors to the Induction and Expression of LTP
Science, 1988The contributions of two subclasses of excitatory amino acid transmitter receptors to the induction and expression of long-term potentiation (LTP) were analyzed in hippocampal slices. The quisqualate/kainate receptor antagonist DNQX (6,7-dinitroquinoxaline-2,3-dione) blocked 85% of the evoked field potential, leaving a small response that ...

Presynaptic induction and expression of NMDA-dependent LTP
Trends in Neurosciences, 2004It is almost axiomatic in neuroscience that postsynaptically induced NMDA-dependent long-term potentiation (LTP) is a cellular substrate of memory. As a result, memory impairments caused by experimental reductions of NMDA currents are often interpreted as evidence that this form of plasticity is involved in memory formation.

Parameters of LTP induction modulate network categorization behavior [PDF]
, 1997 Long-term potentiation (LTP) can only be induced at a synapse up to a fixed maximum extent; the magnitude of this ceiling has been found to be modulated by both endogenous and exogenous factors. The effect of the LTP ceiling on network-level categorization performance in a simulated layer of cortical neurons is investigated. The simulation is presented

Mechanisms of LTP induction in rat motor cortex in vitro.
Cerebral Cortex, 1995The motor cortex displays remarkable plasticity in response to changes in sensory and motor experience; however, the synaptic mechanisms underlying functional plasticity are not known. It is believed that synaptic processes that alter the strength of neuronal connections, such as long-term potentiation (LTP), are mechanisms by which synaptic circuits ...

Dendritic spine density and LTP induction in cultured hippocampal slices.
Journal of Neurophysiology, 1997Collin, Carlos, Katsuyuki Miyaguchi, and Menahem Segal.Dendritic spine density and LTP induction in cultured hippocampal slices. J. Neurophysiol. 77: 1614–1623, 1997. Transverse hippocampal slices were cut from 8- to 9-day-old rats and maintained in an interface chamber for periods of 1–4 wk, in tissue culture conditions.

Requirement of a Critical Period of Transcription for Induction of a Late Phase of LTP
Science, 1994Repeated high-frequency trains of stimuli induce long-term potentiation (LTP) in the CA1 region that persists for up to 8 hours in hippocampal slices and for days in intact animals. This long time course has made LTP an attractive model for certain forms of long-term memory in the mammalian brain.

Inhibition of Postsynaptic PKC or CaMKII Blocks Induction But Not Expression of LTP
Science, 1989Long-term potentiation (LTP) of synaptic transmission is a widely studied cellular example of synaptic plasticity. However, the identity, localization, and interplay among the biochemical signals underlying LTP remain unclear. Intracellular microelectrodes have been used to record synaptic potentials and deliver protein kinase inhibitors ...

LTD induction suppresses LTP-induced hippocampal adult neurogenesis
NeuroReport, 2009Neurogenesis persists in certain adult brain regions including the dentate gyrus. Recent studies have shown that long-term potentiation (LTP) induction in the afferent pathway enhances adult neurogenesis in the dentate gyrus. Here, we investigated whether long-term depression (LTD) induction also affects adult neurogenesis.

Induction of LTP in rat primary visual cortex: tetanus parameters
Brain Research, 1989Long-term potentiation (LTP), intensively studied in the hippocampus as a possible mnemonic device, has begun to be studied in the neocortex. In this study the effects of varying tetanic stimulus parameters on LTP of field potentials recorded from layer II/III induced by white matter stimulation in the in vitro rat visual cortical slice were examined ...
