Exploring the language basis of reading development and reading
disorders using MEG
Among investigators in the field of reading there is a strong consensus
supporting the role of phonological processing in reading development
and disorders. Not surprisingly, neuroimaging studies of dyslexia have
focussed on a phonological core deficit. Clearly, however, skilled
reading involves bottom-up and top-down processes. Additionally,
evidence from neuroimaging studies of reading suggests that language
factors ( e.g., phonological, semantic) impact not just independent
areas but affect activation in a shared functional network of
fronto-temporal areas involved in reading. The dynamics of the
relationship between these variables in children vs. adults will be
illustrated with data from ongoing MEG studies, which has implications
for studies of developmental reading disability.
