Abstract
The membrane current in a locust muscle fiber was characterized by an early but slow inward current followed by a small late outward current in a solution containing Ca and tetraethylammonium (TEA). The maximum inward current decreased with decreasing Ca concentration, almost disappearing upon complete removal of Ca. The inward current has so far not been found in the standard saline. The results indicate that the inward currents are carried by Ca ions.Keywords
