[Abstract] Objective: Voxel-based morphometry (VBM) was applied to investigate the effect of second language acquisition on brain microstructure.Materials and Methods: By PHILIPS 3.0 T magnetic resonance of 35 skilled master Tibetan-Chinese bilinguals Tibetan health volunteers and 35 Chinese monolinguals healthy volunteers underwent whole brain scan, then we applied the VBM technology to analyze the obtained T1-3D brain structural images.Results: Compared to Chinese, Tibetan bilinguals brain areas increased in grey matter volume including: left postcentral gyrus, left supramarginal gyrus, left superior temporal gyrus, right superior temporal gyrus, right putamen, right inferior parietal lobule, cerebellar brain regions.Conclusion: The acquisition of second language can lead to an increase in the volume of some brain language areas, and bilingual learning can promote the development of cortical areas in th brain language.
