Methods of parameters measuring of two equivalent electrical circuits of living tissues

Abstract

Abstract. Two equivalent electrical circuits simulating electrical properties of living tissues are analyzed. For each of these circuits expressions for calculation of their parameters on the basis of experimental measurements of frequency dependencies of active and reactive resistance of living tissue are obtained, and it is sufficiently these measurements to made at low frequencies which expand possibilities of measurements and provide the avoidance of frequency dependence of these parameters. For one of these schemes, these are such parameters as the electrical capacity of the intercellular substance – membrane - cytoplasm system (transmembrane capacity) (C), membrane resistance Rm and intracellular resistance Ri, and for the other, the same parameters C and Ri and intercellular substance resistance Re.
