### About two years go there was article in Sciece, showing very
specific activation in
the anterior cingulate cortex and in the dorsolateral prefrontal cortex in
tasks highly dependent on the g-factor. This indicates that these two
areas could be responsible for at least a part of the variane of g in the
general population.
