Effect of DHPs on transmitter release evoked by high external K⁺. a, Graphs showing the effect of 3 μm Nife (left) and 10 μm Bay-K 8644 (right) on the frequency of sIPSCs recorded in P6–P7 IHCs (top) and P9–P11 IHCs (bottom) during application of an external solution containing 15–25 mm K⁺. b, Representative traces recorded before and after incubation with 3 μm Nife (top) and 10 μm Bay-K (bottom) in P6–P7 IHCs. Vertical scale bars, 50 pA; horizontal scale bars, 1 s. Error bars indicate SEM. *p < 0.05.
