  • Title: Late sodium current in the node of Ranvier.
    Author: Dubois JM, Bergman C.
    Journal: Pflugers Arch; 1975; 357(1-2):145-8. PubMed ID: 1080274.
    Abstract:
    Voltage clamp experiments carried out on nodes of Ranvier of myelinated fibres of Rana esculenta showed that a small fractoon of sodium channels fail to inactivate. Thus during long lasting depolarizing pulses there is a small Na-current superimposed on the leakage and potassium currents. This late Na-current appears more marked in sensory fibres than in motor ones.
