P29: Changes in Thickness and Intelligence

Neuroimaging research indicates that human intellectual ability is associated to brain structure including the thickness of the cerebral cortex. Most studies show that general intelligence is positively associated with cortical thickness in areas of association cortex allocated throughout both brain hemispheres. Changes in cortical thickness over time have been related to intelligence, but whet...

Using IQ discrepancy scores to examine the neural correlates of specific cognitive abilities.

The underlying neural determinants of general intelligence have been studied intensively, and seem to derive from the anatomical and functional characteristics of a frontoparietal network. Little is known, however, about the underlying neural correlates of domain-specific cognitive abilities, the other factors hypothesized to explain individual performance on intelligence tests. Previous prelim...

Neural efficiency in working memory tasks: The impact of task demand and training

Studies of human intelligence provide strong evidence for the neural efficiency hypothesis: More efficient brain functioning in more intelligent individuals, that is, less cortical activation in brighter individuals. The main goal of this study was to explore the relationship between intelligence and cortical activation in combination with a cognitive training. In 83 participants, cortical acti...

Neuroanatomical and neurofunctional markers of social cognition in autism spectrum disorder.

Social impairments in autism spectrum disorder (ASD), a hallmark feature of its diagnosis, may underlie specific neural signatures that can aid in differentiating between those with and without ASD. To assess common and consistent patterns of differences in brain responses underlying social cognition in ASD, this study applied an activation likelihood estimation (ALE) meta-analysis to results f...
