title: Awake craniotomy in glioma surgery.
abstract: Awake craniotomy is the cheapest and most reliable method to ensure neurological integrity in cerebral gliomas that infiltrate or come close to the eloquent areas of the brain, allowing (a) the localization of eloquent cortical areas by electrical stimulation and epileptic foci by cortical recording, and (b) the monitoring of the functional integrity of awake patients while aiming at subtotal removal of the gliomatous tissue. In addition, awake craniotomy opens a brief but unique window to the living brain for (a) basic neuroscience, including verification of preoperative functional imaging data and recording of electrophysiological correlates of mental processes, and for (b) applied research, including development of innovative instrumentation for brain recording and monitoring as well as screening for potential areas to be modulated in movement disorders and chronic pain.
