Förändringar i cellmembranets laddningspotential på den närmsta nervcellen när en impuls med aktiverande verkan når synapsen. Vad som sker är en lokal förändring mot depolarisering. Summering av dessa potentialer kan få nervcellen att avge en urladdningsimpuls.
Depolarization of membrane potentials at the SYNAPTIC MEMBRANES of target neurons during neurotransmission. Excitatory postsynaptic potentials can singly or in summation reach the trigger threshold for ACTION POTENTIALS.
