Pharmacological characterization of four I_Ba components by sequential application of each VDCC blocker. (a) Typical superimposed I_Ba traces at the times indicated in the time-course graph b. (b) Typical time course of sequential application of each selective VDCC blocker on I_Ba. ω-CgTx GVIA, ω-Aga IVA, Nif and Cd²⁺ were bath applied during the time indicated by the filled bar. ω-CgTx GVIA, ω-Aga IVA, Nif and Cd²⁺ were bath-applied during the time indicated by each bar. (c) Summary of the distribution of VDCC subtypes.
