Science Daily: Smart people have better connected brains - In intelligent persons, some brain regions interact more closely, while others de-couple themselves

summary - Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people's brains also wired differently to those of less intelligent persons? A new study supports this assumption. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.
