Summary:The article deals with dispersion of dielectric constant and specific resistance of myelin obtained by the Autilio method from white substance of the cattle brain within frequency range of 90 Hz-100 kHz at a temperature of 20 degrees C as well as with instability of these parameters for 60 min at frequencies of 110, 10(3) and 10(4) Hz. Myelin has an extremely high dielectric constant, which might be due to the presence of water and a macromolecular structure. The result of the measurements are of interest when comparing and adding some details to the data of the microelectrode studies.
