Examples of long-term potentiation
WebFor example, in the CA3 region of the hippocampus, two apparently distinct forms of LTP have been described. One of these is classical N-methyl-d-aspartate ... Long-term potentiation (LTP) was first described in the hippocampus by pioneering work from Tim Bliss and Terje Lømo in the early part of the 1970s. These seminal studies quickly led to ... WebLong-term depression ( LTD) is a phenomenon that is the opposite of long-term potentiation (LTP). In LTD, communication across the synapse is silenced. LTD plays an important role in the cerebellum, in implicit procedural memory, where the neural networks involved in erroneous movements are inhibited by the silencing of their synaptic …

WebAn enduring form of synaptic plasticity called long-term potentiation (LTP) is believed to be involved in many examples of declarative memory. It is present in the hippocampus, which is known to be involved in declarative … 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 …
WebJan 1, 2004 · Lynch, MA. Long-Term Potentiation and Memory. Physiol Rev 84: 87–136, 2004; 10.1152/physrev.00014.2003.—One of the most significant challenges in neuroscience is to identify the cellular and molecular processes that underlie learning and memory formation. The past decade has seen remarkable progress in understanding … In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. The opposite of LTP is long-term depression, which produces a long-lasting decrease in synaptic strength.
