Quantitative and Molecular Genetic Analysis of Cognition. This study attempts to unravel the pathways through which genes may exert their influence on cognitive processes by identifying some of the genes associated with normal variation in cognitive ability. Using the cognitive phenotypes we have collected, both linkage and association analysis will be used to find QTLs (locations on the chromosomes at which specific genes contribute to a quantitative trait) associated with processing speed and other specific abilities. The research will enhance our understanding of the biological mechanisms influencing brain function and paves the way for the genetic dissection of the brain.
