Structural imaging applied to children with wide ranging mathematical abilities has the potential to elucidate the question of what neural circuits underly computation based tasks. The present investigation analyzed the myelin water fraction images of 20 children in a standard space to deduce correlations between myelin content and math abilities. Subjects wrote a calculation-based test and an applied problem-based test. The results implicated occipital/parietal white matter, the right anterior limb of the internal capsule and the left external capsule with positive correlations of 0.61,0.65 and 0.60, respectively.
