Research Abstract

We postulated that the development of the brain, which is the biological foundation of language, facilitates language acquisition during infancy. In this project, we used functional neuroimaging to examine how infants perceive information in spoken language. We found that, in 3-month-old infants, the presentation of speech sounds resulted in selective activation in localized brain regions and modulation of the functional relationship between multiple cortical regions. Our findings indicated the importance of determining the interaction between the structural and functional development of the brain to elucidate the nature of language and, further, of human beings.
