Ultrasound releases drug to alter activity in targeted brain areas in rats

Scientists have developed a noninvasive way of delivering drugs to within a few millimeters of a desired point in the brain. The method, tested in rats, uses focused ultrasound to jiggle drug molecules loose from nanoparticle 'cages' that have been injected into the bloodstream.
