long-term potentiation

n.
Repeated presynaptic stimulation of a nerve, either naturally or in vitro, that results in the long-lasting increased strength of a synapse and is thought to be necessary for learning and memory formation.

long-term potentiation

A persistent increase in effectiveness of some synapses when frequently activated.
