You'd think that a drug prescribed to 10 million Americans would be well understood. But until now, scientists haven't firmly grasped why Ritalin helps the scatterbrained. In a University of Wisconsin-Madison study published recently in Biological Psychiatry, researchers found that the stimulant works by optimizing brain signals in the prefrontal cortex.
The researchers fed rats different doses of Ritalin and then studied their neural activity, which was measured by electrodes implanted in their brains.
