Goodrich-Hunsaker, Naomi J.; Wong, Ling M.; McLennan, Yingratana; Srivastava, Siddharth; Tassone, Flora; Harvey, Danielle; Rivera, Susan M.; Simon, Tony J. – Brain and Cognition, 2011
The high frequency of the fragile X premutation in the general population and its emerging neurocognitive implications highlight the need to investigate the effects of the premutation on lifespan cognitive development. Until recently, cognitive function in fragile X premutation carriers (fXPCs) was presumed to be unaffected by the mutation. Here…

Schmithorst, Vincent J.; Yuan, Weihong – Brain and Cognition, 2010
Previous volumetric developmental MRI studies of the brain have shown white matter development continuing through adolescence and into adulthood. This review presents current findings regarding white matter development and organization from diffusion MRI studies. The general trend during adolescence (age 12-18 years) is towards increasing…

Thareja, Tarika; Ballantyne, Angela O.; Trauner, Doris A. – Brain and Cognition, 2012
This study was conducted to determine whether school-aged children who had experienced a perinatal stroke demonstrate evidence of persistent spatial neglect, and if such neglect was specific to the visual domain or was more generalized. Two studies were carried out. In the first, 38 children with either left hemisphere (LH) or right hemisphere…

Rabinowicz, Theodore; Petetot, Jean MacDonald-Comber; Khoury, Jane C.; de Courten-Myers, Gabrielle M. – Brain and Cognition, 2009
During adolescence, cognitive abilities increase robustly. To search for possible related structural alterations of the cerebral cortex, we measured neuronal soma dimension (NSD = width times height), cortical thickness and neuronal densities in different types of neocortex in post-mortem brains of five 12-16 and five 17-24 year-olds (each 2F,…

Luna, Beatriz; Padmanabhan, Aarthi; O'Hearn, Kirsten – Brain and Cognition, 2010
Cognitive control, the ability to voluntarily guide our behavior, continues to improve throughout adolescence. Below we review the literature on age-related changes in brain function related to response inhibition and working memory, which support cognitive control. Findings from studies using functional magnetic resonance imaging (fMRI) indicate…

Taylor, Nicole M.; Jakobson, Lorna S. – Brain and Cognition, 2010
The term "representational momentum" (RM) refers to the idea that our memory representations for moving objects incorporate information about movement--a fact that can lead us to make errors when judging an object's location (the RM effect). In this study, we explored the RM effect in a sample of children born very prematurely and a sample born at…
