Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.
LTP may refer to: Biology and medicine. Lateral tibial plateau, part of a leg bone; Lipid transfer proteins, proteins found in plant tissues;
The induction of NMDA receptor-dependent long-term potentiation (LTP) in chemical synapses in the brain occurs via a fairly straightforward mechanism. [1] [2] A substantial and rapid rise in calcium ion concentration inside the postsynaptic cell (or more specifically, within the dendritic spine) is most possibly all that is required to induce LTP.
It has been proposed that long-term potentiation is composed of at least two different phases: [4] protein synthesis-independent E-LTP (early LTP) and protein synthesis-dependent L-LTP (late LTP). A single train of high-frequency stimuli is needed to trigger E-LTP that begins right after the stimulation, lasting a few hours or less, and ...
MDT – modular formation dynamic tester, a tool used to get formation pressure in the hole (not borehole pressure which the PWD does). MDT could be run on Wireline or on the Drill Pipe; MDR – mud damage removal (acid bullheading) MEA – monoethanolamine; MEG – monoethylene glycol; MEIC – Mechanical Electrical Instrumentation Commission
Local tangent plane coordinates (LTP) are part of a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation. They are also known as local ellipsoidal system , [ 1 ] [ 2 ] local geodetic coordinate system , [ 3 ] local vertical, local horizontal coordinates ( LVLH ), or ...

This property of the NMDA receptor explains many aspects of long-term potentiation (LTP) and synaptic plasticity. [ 118 ] In a resting-membrane potential , the NMDA receptor pore is opened allowing for an influx of external magnesium ions binding to prevent further ion permeation. [ 119 ]
