Mapping brain functions using electric stimulation during surgery

Pilot Study: Measure of the Potential Evoked With Electroencephalography and Electrocorticography by Electric Stimulation of the Brain During the Neurosurgery Awakened of the Infiltrative Glioma of Low Grade (OMS Type II)

NA · University Hospital, Montpellier · NCT02509442

This study is testing how electric impulses during awake surgery for brain tumors can help us understand which parts of the brain are affected and how they work.

What this trial studies

This study investigates how electric impulses delivered during awake surgery for low-grade infiltrative gliomas affect brain function. Twelve patients will undergo surgery at the CHU of Montpellier, where their brain activity will be monitored using electroencephalography and electrocorticography before and after tumor resection. The goal is to analyze the propagation of these electric impulses and identify the neural networks that are inhibited. Data will be processed and analyzed using specialized software to enhance our understanding of brain function mapping.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with low-grade infiltrative gliomas who are undergoing their first awake surgery.

Not a fit: Patients with significant neurological or psychiatric disorders, or those with a history of severe cranial trauma, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and functional preservation for patients with low-grade gliomas.

How similar studies have performed: Other studies utilizing direct electric stimulation for brain mapping have shown promising results, indicating potential for success in this approach.
