Speeding Up Brain Networks Might Boost IQ

From New Scientist:

For decades scientists have tried, mostly in vain, to explain where intelligence resides in our brains. The answer, a new study suggests, is everywhere.

After analysing the brain as an incredibly dense network of interconnected points, a team of Dutch scientists has found that the most efficiently wired brains tend to belong to the most intelligent people.

And improving this efficiency with drugs offers a tantalising – though still unproven – means of boosting intelligence, say researchers.

The concept of a networked brain isn't so different from the transportation grids used by cars and planes, says Martijn van den Heuvel, a neuroscientist at Utrecht University Medical Center who led the new study.
