Scientists at the Massachusetts Institute of Technology have discovered that one part of the brain "pays attention" and another part of the brain "gets distracted" at the same time.

Their research has implications for helping people with Attention Deficit Disorder.

"The ability to willfully focus your attention is physically separate in the brain from distracting things grabbing your attention," Earl Miller, the neuroscientist who led the study, said.

Miller's team trained monkeys to pick out red triangles on a video screen in return for a treat. However, sometimes the monkeys were deliberately distracted from their task by flashing bright rectangles. During times of concentration, the executive centers of the monkeys' brains in their prefrontal cortexes were in charge. However, when they were distracted, their parietal cortexes near the back of their brains took over. This study is the first time that scientists got a good look at how these regions of the brain work.

Miller said that it is their hope to find treatments to boost attention. This study appears in the March 30, 2007 edition of Science.
