A and B, Single-channel recordings of NSCCs in outside-out configuration at voltages indicated adjacent to traces. External solution contained 50 mm NaCl and either 5 mm CaCl₂ (A) or 0.5 mm CaCl₂ (B). C, I/V relations of unitary NSCCs (outside: 50 mm NaCl) at 0.5 (triangles) and 5 (circles) mm CaCl₂ with unitary conductances of 10.5 and 7.5 pS, respectively. Data were collected from five independent recordings. D, Dependence of open probability on membrane voltage (5 mm CaCl₂, 100 mm NaCl); data were obtained from three independent recordings.
