Figure 11. The replacement of Cl⁻ with gluconate affected both the zero current potential and I_H.

A, representative current traces of whole-cell recordings of a nodose neuron in a potassium solution containing either Cl⁻ (solution 2; A) or gluconate (solution 3; B). The arrow (B) showed the inward potassium tail currents. C, mean (n= 6) currents measured at the steady-state component in the presence (^) and absence (•) of Cl⁻.
