The impact of pentylenetetrazol-induced kindling on the effectiveness of theta pattern primed-bursts (PBs) for the induction of long-term potentiation (LTP) of field excitatory postsynaptic potentials (fEPSP) and population spikes (PS) were investigated in hippocampal CA1 of pentylenetetrazol-kindled rats in vivo. The results showed that shortly after kindling, control animals had normal LTP of...

Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulation. The role of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in excitatory synaptic tran...

introduction: generally, nmda receptor antagonists inhibit learning and long-term potentiation (ltp). however, it has been suggested that direct tonic activation of nmda receptors, in contrast to learning, may lead to an increase in synaptic “noise”. uncompetitive nmda receptor antagonist memantine can paradoxically reverse deficits in learning and synaptic plasticity, and restore ltp impaired ...

Long-term potentiation (LTP) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. The first clue of the potential role of glutamate receptors in LTP was in 1991 with the observation that the mGluR agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (ACPD), increased LTP. Studies have shown that ACPD induc...

There have been continual attempts to identify alternatives increase the agricultural output improve living standards of farmers, meet current demand, and promote sustainability in commercial agriculture. Within this paradigm, low-temperature plasma (LTP) treatments piqued attention investigators are presently being extensively researched agriculture sector. A preliminary study was conducted on...

The maintenance of synaptic changes resulting from long-term potentiation (LTP) is essential for brain function such as memory and learning. Different LTP phases have been associated with diverse molecular processes pathways, the underpinnings on short, well long time scales, are established. However, principles intermediate scale 1-6 hours that mediate early phase (E-LTP) remain elusive. We hy...

  The effects of chronic morphine administration on the development of long-term potentiation (LTP) were investigated at the Schaffer collateral-CA1 pyramidal cell synapses of the rat hippocampal slices using primed-bursts tetanic stimulation. Significant enhancement of orthodromic population spike (OPS) was found for all stimulus intensities after tetanic stimulation. OPS enhancement was great...
