Abstract : The hydrogen technique for measuring blood flow has been modified and adapted to study focal cerebral blood flow. In the implanted depth-electrodes platinum is now used and it is thus possible to monitor with a scanner focal intracerebral blood flow from 20 electrodes in each patient. The data are collected on punch tape and fed to a computer for mathematical handling. In 9 patients, undergoing depth-electrographic study and treatment, supplementary diagnostical data have been collected through the blood flow study in the immediate post-operative period and later. The technique has been developed further for the study of changes in flow of only minutes' duration. Preliminary results have indicated that focal differentiated changes in blood flow occur in some of the mid-line regions in response to reading and motor activity. The observations in the post-operative period have given promising information about the blood circulation in the patient's brain. The results give promise for improved treatment and understanding of head injuries and complications following brain surgery. This is of great importance for the Army in times of combat. (Author)
