WebAbstract. Long-term potentiation and long-term depression (LTP/LTD) can be elicited by activating N-methyl-d-aspartate (NMDA)-type glutamate receptors, typically by the coincident activity of pre- and postsynaptic neurons.The early phases of expression are mediated by a redistribution of AMPA-type glutamate receptors: More receptors are … WebMay 5, 2024 · Indeed, the link between Arc and cellular calcium , the involvement of Arc in late-phase LTP , and the interaction of Arc and CREB-binding protein have been reported. Second, SD-induced genes that are inhibited by Arc loss are all immediate early genes, except for Bip/Grp78 (Fig. 3 C–G).

NMDA receptor-dependent LTP exhibits several properties, including input specificity, associativity, cooperativity, and persistence. Input specificity Once induced, LTP at one synapse does not spread to other synapses; rather LTP is input specific. Long-term potentiation is only propagated to those synapses according to the rules of associativity and coop… WebNov 27, 2024 · Here, we show for the first time that each AKT isoform has a distinct expression pattern in the hippocampus.
