Figure 9. Effects of Ba²⁺, Cs⁺, Co²⁺, Ni²⁺ and Cd²⁺ on the PA current I-V curves.

All I-V curves were generated from the same TRC. The patch pipette was filled with intracellular NMG solution (4 mm KCl). The TRC was stimulated by extracellular NMG solution with 110 mm NMG or 100 mm NMG + 10 mm KCl and those containing the particular blocker (A: Ba²⁺, Cs⁺; B: Co²⁺, Ni²⁺, Cd²⁺).
