Abstract
The use of small bipolar needle electrodes for the measurement of the capacitive properties of the brain tissue was found to be unsatisfactory. Electrode polarization effects, acting as a parasitaric phenomena, are the main obstacle of this method; thus, the values of capacitance obtained do not represent the capacitive properties of the tissue. In order to overcome the above difficulties, a comparison method was employed by which the electrical parameters measured in brain tissue were compared with the values obtained from an electrolyte solution of the same resistance.This publication has 1 reference indexed in Scilit:
