Concept

long-term potentiation

A brain with molecular structures extending from it symbolizes long-term potentiation (LTP), a process where synaptic transmission strengthens after high-frequency stimulation.

A long-lasting strengthening of synaptic transmission after a burst of high-frequency stimulation, first observed by Terje Lømo in rabbit hippocampus in 1966. LTP is the leading cellular candidate for how learning and memory are stored in the brain. It depends on NMDA receptors and on the insertion of additional glutamate receptors into the post-synaptic membrane, increasing the response to subsequent signals.
