Voltage dependency of K_v currents.

Parameters of I–V curves fitted to the Boltzmann distribution with V1/2 being the half maximal activation/inactivation, and dV the slope of the voltage dependency. Control inactivation data of the sustained current (s.c.) best fit with a sum of two Boltzmann equations, and because the first component had values similar to the transient current (t.c., IA), only the values of the more depolarized component, assumed to represent IK, are shown. All data presented as mean±SD.
