Demonstration of the ability of MPnRAGE to correct for severe motion artifacts in a 7 year old girl.  Retrospective motion correction greatly reduced motion-induced blurring in both  structural T1-weighted images and quantitative T1 maps.  The correction greatly improves the reliability of brain imaging measurements in children.  The plots indicate the estimated amount of head motions that were corrected.

White matter microstructure, essential for efficient and coordinated transmission of neural communications, undergoes pronounced development during the first years of life, while deviations to this neurodevelopmental trajectory likely result in alterations of brain connectivity relevant to behavior. Hence, systematic evaluation of white matter microstructure in the normative brain is critical for a neuroscientific approach to both typical and atypical early behavioral development.

Fraction Understanding in 8th Graders

The Educational Neuroscience Lab and Mathematics Education Learning & Development Lab are working with the Waisman Center to investigate the development of fraction knowledge in children. Knowledge of fractions and mathematical competence are important determinants …
