About

This study proposes to analyze data from intraoperative ECoG recordings acquired during wakefulness interventions in order to identify the connection networks involved in cognitive functions. This study also proposes to correlate the ECoG data with the imaging data and to analyze the disturbances of the electrophysiological signals induced by the cortical and subcortical brain lesions: this will make it possible to establish a more detailed mapping of the tumor areas and to compare disturbances recorded to those recorded in healthy areas. Thus, this approach should make it possible to improve the quality of excision of glial lesions located in eloquent areas, while reducing the risk of neurological sequelae and thus improve the survival and quality of life of patients.
