Abstract and Keywords
When seeking to uncover the brain correlates of language processing, timing and location are of the essence. Magnetoencephalography (MEG) offers them both, with the highest sensitivity to cortical activity. MEG has shown its worth in revealing cortical dynamics of reading, speech perception, and speech production in adults and children, in unimpaired language processing as well as developmental and acquired language disorders. The MEG signals, once recorded, provide an extensive selection of measures for examination of neural processing. Like all other neuroimaging tools, MEG has its own strengths and limitations of which the user should be aware in order to make the best possible use of this powerful method and to generate meaningful and reliable scientific data. This chapter reviews MEG methodology and how MEG has been used to study the cortical dynamics of language.

She has pioneered the use of magnetoencephalography (MEG) in language research, and has a strong track record in multidisciplinary neuroscience research and training. She has edited the handbook MEG: An Introduction to Methods (Oxford University Press 2010) and serves as Associate Editor of the journal Human Brain Mapping.
Jan Kujala is a Staff Scientist at the Department of Neuroscience and Biomedical Engineering, Aalto University, Finland. He has introduced and actively develops magnetoencephalography (MEG)-based methods for investigating cortico-cortical connectivity and applying them in the language domain.
Mia Liljeström received her doctoral degree from Aalto University, Finland. She is currently working at the Department of Neuroscience and Biomedical Engineering at Aalto University, Finland, where she combines magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) to study large-scale functional networks underlying language and speech.
