Assessment of Awake Surgery With Electrocorticographic Recordings in the Management of Gliomas and Correlation With Imaging Data (ECoG)

"The skull and the dura are opened under general anesthesia and the two grids of 64 cortical electrodes will be applied to the cortex, one facing the glial lesion, and the other at a distance from the glial lesion in the so-called area. Healthy (non-tumor), before the patient wakes up. They consist of 8 recording slides each comprising 8 electrodes of 2 mm in diameter each spaced 0.5 mm (DispoMed®, USA)."
