Abstract:

The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI to repress long-term potentiation.

5-HT2 receptor-mediated reversal of the inhibition of hippocampal long-term potentiation by acute inescapable stress.

The serotonergic system is known to modulate and mediate many of the central nervous system effects of stress. Here we investigated the ability of serotonergic agents to reverse the inhibition of the induction of hippocampal long-term potentiation (LTP) caused by prior exposure to inescapable stress. Elevated platform stress prevented the induction of LTP in the CA1 area of anaesthetized rats. ...

P19: Long-Term Potentiation

The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. 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 stimulations. Differe...

P3: Mechanisms of TrkB-Mediated Hippocampal Long-Term Potentiation in Learning and Memory

Long-term potentiation (LTP) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. Studies in recent years indicate the importance of molecular pathways in the development of memory and learning. Tropomyosin receptor kinase B (TrkB) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...

Postsynaptic density-95 mimics and occludes hippocampal long-term potentiation and enhances long-term depression.

Previous studies have shown that overexpression of the protein PSD-95 (postsynaptic density-95) selectively enhances AMPA receptor-mediated synaptic responses in hippocampal pyramidal cells. To determine whether this effect is related to synaptic plasticity at these synapses, we examined whether PSD-95 expression mimics long-term potentiation (LTP), and also whether it influences LTP and long-t...
