Researchers find intelligent people have 'more efficient' brain connections even at rest

Tuning inside the brain is the difference between normal and super smart people, researchers have found. They say general cognitive ability may be the result of a'well-tuned brain network' - and may even be able to develop to tune up the mind of those less intelligent. They found the brains of those with higher intelligence were extremely similar at rest and while carrying out tasks. Researchers say general cognitive ability may be the result of a'well-tuned brain network' - and say they may even be able to develop a way to tune up the mind of those less intelligent. 'Specifically, we found that brain network configuration at rest was already closer to a wide variety of task configurations in intelligent individuals,' the Rutgers University team wrote in The Journal of Neuroscience.
