WebJun 10, 2024 · The quantity of stimulation can be altered to induce either early-LTP or late-LTP. To induce early-LTP, two strategies are mainly used – a weak tetanisation (WTET) of 21 pulses at 100 Hz or a weak TBS with less train quantity []. For long-lasting late-LTP, a strong tetanisation (STET) is induced by 3 trains of HFS 10 min apart [[43-45]]. Such ...

WebLong-lasting forms of memory are generally believed to be mediated by protein synthesis-dependent, late-phase long-term potentiation (L-LTP). L-LTP exhibits at least two distinctive characteristics compared with early phase LTP (E-LTP): synaptic growth and requirement of gene transcription and new protein synthesis. WebThe early (E-LTP) and late (L-LTP) phases of LTP are each characterized by a series of three events: induction, maintenance, and expression. Induction is the process by which a short-lived signal triggers that phase of LTP to begin.

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.
