Abstract
Resistivity values were measured from living human brain tissue in nine pat ients. A monopolar needle electrode was used with a measurement frequency o f 50 kHz. Mean values were 3.51 Ohm m for grey matter and 3.91 Ohm m for wh ite matter. Cerebrospiral fluid had a mean value of 0.80 Ohm m. Values for tumour tissues were dependent on the type of tumour and ranged from 2.30 to 9.70 Ohm m.
