| Outline of Final Research Achievements |
In the present comparative study using functional magnetic resonance imaging (fMRI), we tried to elucidate the neural bases of universality and variability of the human languages. Here we targeted Japanese and Kaqchikel, a Mayan language spoken in Guatemala. In both Kaqchikel and Japanese, we found that the conditions with scrambled sentences elicited significant activation in the left inferior frontal gyrus, which has been proposed as a grammar center, indicating the effects of syntactic loads. Moreover, in Kaqchikel, the conditions without topicalization resulted in significant activation in bilateral Heschl’s and superior temporal gyri, demonstrating that the syntactic and phonological processes were clearly dissociated within the language areas. These results establish that scrambling and topicalization have different impacts on the specified language areas.
