title: Impedance measurements of the spinal cord of man and animals.
abstract: The measurement of electrical impedance of normal and pathologic tissue has not been fully utilized in neurosurgery. This is a report of electrical impedance measurement in the central nervous system of both man and animals. We show the results of the laboratory study done in animals, in the brain and in the spinal cord as well. Also we show the clinical experience of the impedance recordings in the DREZ procedure for some chronic pain conditions, correlating the measurements at the time of the operation with normal conditions, with comments about the findings.
