title: Critical quantum content for shortening of endplate currents in the frog skeletal muscle.
abstract: The decay time of endplate currents was followed during progressive lowering of quantum content of endplate responses by reduced Ca2+. A certain critical value of about 100 quanta was found, when the decay of endplate currents remained constant even though the quantal content was reduced further.
