摘要: Long-term potentiation (LTP) of synaptic transmission is a well defined form neuronal plasticity. The induction LTP at perforant path-dentate granule cell and Schaffer collateral-CA1 pyramidal synapses the hippocampus known to require influx Ca2+ through postsynaptic N-methy1-D-aspartate (NMDA) receptors, while expression has been proposed be mediated least in part presynaptic1) Epileptic seizures which are associated with massive increases intracellular cation concentration may also account for persistent efficacy excitatory hippocampus2) This seizure-induced (SIP) have some features common such as requirement NMDA receptor activation1,3) consequent increase neurotransmitter release4,5). These findings led concept retrograde messenger by presynaptic terminals informed that sites activated. Arachidonic acid (AA) recognized potential candidate messenger1). Here, we addressed involvement lipid peroxides, especially lipoxygenase metabolites,
