WebEn neurosciences, la potentialisation à long terme (PLT) est un renforcement persistant des synapses basé sur les derniers patrons d'activité.. Ces derniers produisent une augmentation durable du taux de transmission du signal entre deux neurones [2].L'opposé de la PLT est la DLT (dépression synaptique à long terme).C'est l'un des nombreux … WebLong-term synaptic plasticity was first reported in 1973.
