CORTICAL-CORTEX EVOKED POTENTIALS IN NEUROSURGERY

Abstract

The article discusses the problem of assessing the state of functional relationships between speech cortical brain areas. The registration of cortical-cortical evoked potentials (CC-EP), problems of registration and interpretation of the results obtained are described. A unique ma-terial in Russia is presented: 27 patients with brain tumors under intraoperative mapping of the cortical speech areas using the CC-EP. The results obtained and options for their interpre-tation are discussed, as well as the prospects for further development of the method. The au-thors present their personal conclusions about the significance of the method and the accuracy of its results, as well as the relationship between the CC-EP parameters and the postoperative clinical state of speech functions in patients after removal of brain tumors.
