[The effect of a lesion of the subcortical conducting pathways on the electrical activity of the human cerebral cortex].
Simultaneous consideration of EEG, neurological, and imaging data obtained with sequelae of ischemic stroke during rehabilitation allowed us to verify the organic nature of some EEG phenomena. It was shown that stroke-induced impaired circulation in the area of the middle brain artery gave rise to deviant local cortical electrical activity (EA) in the form of polymorphic theta and delta waves or groups of theta waves. The character of such activity depended on the lesion size and extent of blood supply deficit in the damaged area. Decrease in the lesion size and restoration of blood supply during rehabilitation were accompanied by changes in the local deviant EA: the polymorphic slow-wave activity was replaced by single alpha and theta sharp waves. The restoration of motor functions was less successful in cases with the local deviant EA localized in the caudal part of the cortex.
