WebIn neuroscience, long-term potentiation ( LTP) is a long-lasting enhancement in signal transmission between two neurons that results from stimulating them synchronously. [2] It is one of several phenomena underlying synaptic plasticity, the ability of chemical synapses to change their strength. WebLong-term synaptic plasticity was first reported in 1973. Studying a pathway in the rabbit hippocampus, researchers discovered that rapidly and repeatedly activating the synapses made them stronger; the volume …
