Concentration of stimulant regulates initial exocytotic molecular plasticity at single cells

Amperometric measurement of exocytosis (SCA) and vesicle content (IVIEC) over 15 s intervals reveals plasticity (none, potentiation, or depression), that is regulated by the concentration of stimulant solution ( e.g. , 30 s 10, 30, 50, and 100 mM K + ).
