Abstract excerpt
The properties of Mg2+ conductances in Paramecium tetraurelia were investigated under two-electrode voltage clamp. When bathed in physiological Mg2+ concentrations (0.5 mm), depolarizing steps from rest elicited a prominent Mg2+-specific current (IMg) that has been noted previously. The dependenc...
