The chapter by David Kennedy explores the utility of advanced imaging techniques in the study of development of the brain. Kennedy's goal is to link observable changes in the brain in the postnatal period to events that occurred in the prenatal period (when direct observation of the brain is not possible). Using examples from three different groups, Kennedy illustrates exactly how one can use comparisons with normative data to make assumptions about the changes that occurred during development. Each of the examples that he provides, while not directly germane to the study of developmental dyslexia, has potential implications for future research on this topic. What is clear is that the field in general will surely benefit from a group effort to share MRI data from children with developmental dyslexia.
