[Effect of the characteristics of indwelling intracerebral gold electrodes on the recording of physiological indices of the brain].

The paper presents results of measuring the electric impedance of an electrolyte solution and cerebral tissue on changes of parameters of the impulse current and contact surface of gold electrodes. During application of DC to cerebral deep structures distant steady potential shifts occurred in the brain regarded as a volume conductor. The polarization properties of the gold indwelled electrodes were estimated under these conditions.
