  How the brain learns a second language after the first language is acquired has been underspecified. The framework of assimilation and accommodation hypotheses has been used to explain the brain’s responses to learning a new language (Perfetti et al., 2007). The assimilation hypothesis predicts that the brain network involved in processing L1 is largely reused during L2 learning. In contrast, the accommodation hypothesis predicts that learning L2 requires involvement of additional brain regions that are not engaged in L1. Previous findings suggest that several variables play an important role in shaping brain activation during L2 reading, such as age of acquisition, proficiency, and exposure to L1 and L2. However, the relationship between L1 and L2 have not gained much attention in neuroimaging studies of language. I will present my recent fMRI studies on how language distance between L1 and L2 influences the assimilation and accommodation pattern in Korean-Chinese-English trilinguals. The results showed that 1) the brain network involved in L2 reading is similar to the L1 network when L2 and L1 are similar in orthographic transparency (Korean-English), while significant accommodation is expected when L2 is more opaque than L1 (Korean-Chinese), and that 2) important brain regions for L1 are carried over to L2 reading, and higher L2 proficiency was associated with greater involvement of the native language network. These studies provide important evidence for neural plasticity by showing that the bilingual brain selectively engages different regions for different L2s.
