Calcium Dependence of the Inactivation of Calcium Currents in Skeletal Muscle Fibers of an Insect

Calcium currents in skeletal muscle fibers of an insect, Carausius morosus, inactivate under depolarization. This inactivation depends on the current being carried across the membrane by calcium ions, rather than strontium or bariumions.
