Inactivation of the slow potassium outward current in crab muscle fibre.
The slow outward current (IK2) recorded in crab muscle fibre using the double sucrose gap method decreases when high and maintained depolarizations are applied. This decrease corresponds to a true inactivation of the potassium conductance rather than to a shift in the reversal potential of the charge carrying ion following local accumulation.
