Bilingualism is the ability to speak or understand two languages or the regular use of two languages. The aim of the study was to investigate the differences in metaphor processing areas in bilingual and monolingual children based on brain maps. We used the tool for measuring metaphor perception and reaction time in children developed by (Pouscoulous and Tomasello, 2019) and the Quantitative electroencephalogram device. Participants were 30 children aged 7 to 11 years. The results revealed no significant difference between the groups in terms of the correctness of the answer content about the metaphors, According to QEEG analysis, the significant difference in absolute power between the bilingual and monolingual groups is only at point T5 and in beta, beta1 and high beta waves - bilinguals are less than monolinguals - 25, 35 and 19%, respectively.
