Critical quantum content for shortening of endplate currents in the frog skeletal muscle

Critical quantum content for shortening of endplate currents in the frog skeletal muscle

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.
