Web3 de dez. de 2003 · Recent studies have emphasized the importance of temporal order for pairing-induced LTP, whereby the postsynaptic spike must occur within a time window of ∼20 msec after the presynaptic stimulus for potentiation to occur, whereas reversing the order of presynaptic and postsynaptic activity leads to long-term depression (LTD) … WebLong-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.

WebThis is called long-term potentiation, or LTP and it's one example of synaptic plasticity, which is the ability of synapses to change their strength. Let's look at this process in more detail.
