Rich rewards: Scientists reveal ADHD medication's effect on the brain

(Okinawa Institute of Science and Technology (OIST) Graduate University) Researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) have identified how certain areas of the human brain respond to methylphenidate -- a stimulant drug which is used to treat symptoms of ADHD. The work may help researchers understand the precise mechanism of the drug and ultimately develop more targeted medicines for the condition.
