  • Title: [Discontinuous feedback amplifier: principles and application to the measurement of transmembrane potentials and currents of frog atrial fibers].
    Author: Suchaud M, Chesnais JM, Sauviat MP.
    Journal: C R Acad Sci III; 1986; 302(1):15-20. PubMed ID: 3082473.
    Abstract:
    The study and achievement of a discontinuous feedback amplifier to measure membrane potentials and currents in frog atrial fibres using the double sucrose gap technique was achieved. It was shown that, with the present device, the effects of the resistance in series with the membrane resistance and the membrane capacity on the measure of cardiac membrane potentials and fast currents are markedly reduced.
