Child MEG for the study of language acquisition and language impairment

Abstract/Résumé: Magnetoencephalography (MEG) is an important technique for functional neuroimaging of language function and language impairments in the brain. It has excellent temporal resolution, good spatial resolution, and is safe for routine use even with children. One important limitation of conventional MEG systems is that they have been designed to provide optimum coverage of the adult brain and are not well-suited for use with children less than six years. A recent innovation is the development of a child MEG system, custom-sized to accommodate the heads of three- to five–year-olds. This novel MEG has opened a new window into the study of brain mechanisms of typical and atypical language acquisition. In this presentation we describe several current child MEG studies of language and language-related processes in the brains of pre-schoolers, conducted at the KIT-Macquarie Brain Research Laboratory. The results of these studies provide new insights into human brain development and address an important gap in the human neuroimaging literature.
