Application of CT-directed Stereotaxy in the Determination of Functional Neurosurgical Targets in the Diencephalon and Cerebral Hemisphere

Abstract

The descriptions of two techniques allowing for CT target determination in functional neurosurgery are presented, the first for thalamic and peri-thalamic explorations in the treatment of dyskinesiae and chronic pain, the second for the implantation of multiple hemispheric depth electrodes in the assessment of chronic drug-resistant epilepsy.
