Early long-term potentiation (E-LTP) is the first phase of long-term potentiation (LTP), a well-studied form of synaptic plasticity, and consists of an increase in synaptic strength. LTP could be produced by repetitive stimulation of the presynaptic terminals, and it is believed to play a role in memory function in … See more It has been proposed that long-term potentiation is composed of at least two different phases: protein synthesis-independent E-LTP (early LTP) and protein synthesis-dependent L-LTP (late LTP).

"Websustain LTP into its late form. Overall, LTP can manifest in both early and late forms. Early-LTP can exist independent of protein synthesis but will decay over time. On the other hand, late-LTP is protein synthesis-dependent and is long-lasting.
