Long term potentiation disruption
WebSynthetic, cell, and brain derived Aβ oligomers have been found to inhibit hippocampal long-term potentiation (LTP) and this effect can be suppressed by the blockage of Aβ oligomer formation. A large body of evidence suggests that Aβ oligomers inhibit N-methyl-D-aspartate receptor dependent LTP; additional receptors have also been found to elicit downstream … WebImpairment of long-term potentiation induction is essential for the disruption of spatial memory after microwave exposure Int J Radiat Biol. 2013 Dec;89(12):1100-7. doi: …
