| Abstract | Linguistic information is processed at distinct levels from words to sentences and discourse. Linguistic information at the word level, including phonology and lexico-semantics, would be processed in the temporal and parietal regions of the left brain, whereas left frontal regions play an important role in the process of constructing sentence structures by applying grammatical knowledge. We have used functional magnetic resonance imaging, and have shown that the opercular and triangular parts of the left inferior frontal gyrus (L.F3op/F3t) and the left lateral premotor cortex (L.LPMC) are critically involved in syntactic processing. Moreover, we have recently demonstrated that a glioma in the L.F3op/F3t or L.LPMC is sufficient to cause selective deficits in syntactic processing. These results support the module hypothesis of human language. |
