Abstract:
ObjectiveTo investigate the language cortex organization characteristics of native Chinese. Methods20 patients who underwent language mapping via intraoperative direct cortical electrical stimulation (ioDCES) under awake anaesthesia for glioma in dominant hemisphere were analyzed retrospectively. Results16 patients were identified at least one language site, 3 patients located in the frontal and 1 patient in the temporal lobe. The language sites mostly located in the perisylvian region. The frontal language sites conformed to traditional Broca's areas, but the superior temporal gyrus contained much more language sites than the middle temporal gyrus.ConclusionHigh individual variability in language organization indicates a need for revision of the classical model of language localization. Because of the samples were too small, our current dates can't fully reflect language cortex organization characteristics of native Chinese.
