Abstract
The in vivo measurement of specific impedance in animal brain tissue involves several technical aspects. The most stringent difficulties relate to electrode polarization and spatial resolution of the measuring system. The polarization is solved by using a 4 electrode arrangement with a very high impedance preamplifier on the potential electrodes. The relative effectiveness of the various possible linear configurations of 4 electrodes was discussed in terms of spatial resolution. The accuracy of computed spatial resolution with respect to corresponding experimental ones is specified.This publication has 8 references indexed in Scilit:
