just a pointer to a great SciVee episode – Genetic Contribution To Variation In Cognitive Function In Twins
Their data suggest that genetic influences on cognitive function act outside of the brain areas most commonly activated during cognitive tasks. The areas where genes seem to exert influence on brain activity are quite variable from person to person (which is why they don’t show up in group-level analyses). Thus folks with different genetic variability use slightly different brain areas to accomplish the same cognitive task.
