Abstract

Recent neuroimaging studies have drawn a heterogeneous picture on the cerebral organization of a first language(L1) and a second language(L2). There had been some evidences that L1 and L2 are supported by identical brain regions, whereas contradictory results indicate a differential cerebral organization for L1 and L2. The purpose of the present paper is to see whether brain region activation during lexical decision tasks represents any spatial distinction between L1 and L2. To examine whether the two languages are represented in distinct or overlapping areas of the brain, we applied functional magnetic resonance imaging (fMRI). Twelve right-handed Korean-English bilingual students were scanned during the lexical decision tasks. The cortical activations were compared with the eye fixation(baseline) condition. The contrast between the two languages(Korean, English) in the LDT task against baseline(Fig. 1) indicates the two languages are both represented bilaterally. The activated areas in Korean task were the bilateral IFG, the left cingulated gyrus, the postcentral gyrus and right insula. In English task, the bilateral inferior, medial and middle fronal gyri, the left postcentral gyrus, the left superior parietal gyrus, and fusiform gyrus were involved. It seemed that in the Korean-English late bilinguals lexical processing, distinct bilateral areas are recruited. It suggests the lexicon of the later acquired language should be represented some other place near the native tongue.
