In pre-neurosurgery language mapping it is critical to identify language-specific regions in multilingual speakers. We conducted pre-operative functional magnetic resonance imaging, and intraoperative language mapping in the unique case of a highly proficient quadrilingual with a left frontal brain tumor who acquired her second language at age 5, and her(More)
The Wada test is an invasive procedure used to determine cerebral memory and language dominance as well as risk of cognitive deficits following neurosurgery. However, the potential risks of Wada testing have led some to consider foregoing Wada testing in candidates for resective epilepsy surgery with right hemispheric seizure onset. We present two atypical(More)
INTRODUCTION Grammar is a core component of the language system, yet it is rarely assessed during the Wada (intracarotid amobarbital) test. It is hypothesized that adding grammar tests to the recovery phase of the Wada test will increase our ability to lateralize language function. METHOD Sixteen individuals (nine females, fifteen right-handed, mean age(More)
Intraoperative Electrical Stimulation (IES) of the brain is performed to localise and spare language functional areas before extraction of brain tissue in patients with tumors and epilepsy. The procedure is very precise and highly effective. Yet, it is argued that language tests used during IES are too limited. This article presents new language tests that(More)
