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 ...

Synaptic plasticity leads to long-term changes in excitability, whereas cellular homeostasis maintains excitability. Both these processes involve interactions between molecular events, electrical events, and network activity. Here I explore these intersections with a multilevel model that embeds molecular events following synaptic calcium influx into a

Activation of the glycine site in the NMDA receptor is necessary for the induction of LTP
Neuroscience Letters, 1990The effects of 7-chlorokynurenate (7-C1KY) were examined on N-methyl-D-aspartate (NMDA) receptor-mediated synaptic mechanisms in the CA1 region of rat hippocampal slices. 7-C1KY depressed both the NMDA receptor-mediated component of synaptic transmission recorded in Mg2(+)-free medium and the induction of long-term potentiation (LTP) in Mg2 ...

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.

Induction of LTP and LTD in visual cortex neurones by intracellular tetanization
NeuroReport, 1994Neurones from supragranular layers of rat visual cortex slices were activated by intracellular tetanization (IT) without concomitant presynaptic stimulation. The effect of IT was examined on EPSPs evoked at low stimulation intensity from two subsets of afferents by electrodes positioned in layers II and IV, respectively.

Sexual dimorphism in the induction of LTP: Critical role of tetanizing stimulation
Life Sciences, 2004Numerous studies have suggested that sexual dimorphism may exist in learning and memory, particularly in types involving the hippocampus. In the present study, we examined the effects of two different tetani on the induction of long-term potentiation in the CA1 region of hippocampal slices from adult female and male rats to determine the sexual ...

Evidence for Postsynaptic Induction and Expression of NMDA Receptor Independent LTP
Journal of Neurophysiology, 1998Grover, Lawrence M. Evidence for postsynaptic induction and expression of NMDA receptor independent LTP. J. Neurophysiol. 79: 1167–1182, 1998. Whole cell/patch-clamp and extracellular field potential recordings were used to study the induction and expression of N-methyl-d-aspartate (NMDA) receptor independent long-term potentiation (LTP) in area CA1 of

Activation of M1-like muscarinic receptors is required for the induction of corticostriatal LTP
Neuropharmacology, 1999We studied the role of endogenous acetylcholine (Ach) in corticostriatal long-term potentiation (LTP). The muscarinic receptor antagonists scopolamine and pirenzepine fully prevented the induction of LTP suggesting that the activation of M1-like muscarinic receptors is a crucial event in the conditioning phase of this form of synaptic plasticity.
