Summary

This study is about an experimental biomedical monocentric search concerning twelves patients presenting a infiltrative glioma of low rank OMS type II and realizing a surgery awakened on the site of the CHU of Montpellier.

The objective of this search is to understand exactly how the electric impulses, delivered by the neurosurgeon to make a functional mapping of the brain during the surgery awakened by tumors infiltrates of low rank, propagate in this one and to identify the nervous networks inhibited by these electric impulses.

Having verified the eligibility of the patients and having obtained their consent, they will be included in the study. Before the beginning of the surgery, the electroencephalography activity of the brain of every patient will be recorded. Before and after the surgical resection, the electrocorticography activity will be recorded.

The collected data will then be analyzed, after the operation. Analyses will try to identify what we call potential evoked by the stimulation and which are small electric waves which appear after the electric stimulation was delivered.

Conditions

  • Low Grade Glioma of Brain

Interventions

PROCEDURE

Diffusion of direct electric stimulation

During the neurosurgery awakened consisting in resecting a low-rank infiltrative glioma , the potential evoked further to the direct electric stimulation of the brain will be recorded by electroencephalography and electrocorticography.
