The article addresses the neuroimaging, electrophysiological, and postmortem evidence concerning the neurological basis of dyslexia and concludes that inconsistent findings may be related to limitations of investigative technologies. Correlates of reading ability and disability are discussed in a developmental-neuropsychological context.…

In response to a previous paper (EC 212 858) regarding the neurodevelopmental evidence for the basis of dyslexia, this paper suggests further concerns in the areas of cognitive measurement, the relationship between cortical-functional organization and child development, and lack of operational definitions in the study of the dyslexic syndrome.
