[The topographic EEG mapping of patients with an organic brain lesion].

Brain mapping was carried out in 50 patients with organic brain lesions (tumors, disturbances of vascular circulation, multiple sclerosis, consequences of brain trauma ets.) The parallelism between the severity of the organic brain lesion and the degree of bioelectrical activity disturbances has been discovered. In patients with brain tumors, consequences of the stroke, severe trauma and multiple sclerosis the focuses of pathological activity corresponded to location of the brain lesion.
