title: A calcium dependent inward current in frog skeletal muscle fibres.
abstract: Slow inward currents are here reported in frog skeletal muscle. The currents are turned on by depolarising the membrane beyond about -45mV and are blocked by replacement of Ca2+ by Mg2+ and in the presence of Ca2+ by Co2+ at 20mM.
