fMRI study in twins: genes influence brain activation
Genes may contribute to individual differences in cognitive functions. In a functional magnetic resonance imaging (fMRI) twin study, published in Science, Jan Willem Koten, Jr., Guilherme Wood, Peter Hagoort, Rainer Goebel, Peter Propping, Klaus Willmes and Dorret I. Boomsma found a significant genetic influence on brain activation in neural networks supporting digit working memory tasks.
