... recordings from cultured cells revealed that these cells possess a variety of ionic currents, including a fast transient sodium current, a calcium current and several potassium currents. The sodium current does not inactivate completely but instead decays to a steady-state component which has the same...

An inwardly directed current, blocked by zero-calcium salines, Cd 2+ and verapamil, was considered to be a calcium current whose activation closely matched that of the Ca 2+ -dependent...
