Adult Brains Grow From Specialist Use

Slashdot has this story: Xemu writes "Researchers at University College of London's Institute of Neurology have discovered that taxi drivers grow more brain cells in the area associated with memory. Dr Eleanor Maguire says, 'We believe the brain increased in gray matter volume because of the huge amount of data memorized.' She warns against the use of GPS and says it will possibly affect the brain changes seen in this study. This research is the first to show that the brains of adults can grow in response to specialist use." London cabbies, unlike their American counterparts, have to learn the layout of streets and the locations of thousands of places of interest in order to get a license.
