This study revealed that a higher order visual pathway,
thought to be sensitive to abnormal neurodevelopment,
could be assessed using fMRI in seven-year-old children.
Furthermore, the fMRI results were correlated with
cortical thickness and performance of a visual task
outside of the scanner environment. These findings are
consistent with electrophysiology (in non-human
primates), electroencephalography (EEG), and
magnetoencephalography (MEG) studies in adults. fMRI of
visual brain areas may provide a sensitive biomarker for
abnormal neurodevelopment in children.
