The Conductivity of Brain Tissues: Comparison of Results in Vivo and In Vitro Measurements

Abstract

The electrical properties of tissues depend on many factors, including measurement frequency and temperature. Properties differ also in vivo and in vitro situations. The authors have collected conductivity values from several studies and compared the values measured from living tissue and tissue samples. The results show that, after death, the resistivity ratio of grey and white matter increases 36%, and the resistivity values increase over 100%. (24 references)
