Brain scans reveal drugs’ effects on attention

Scientists have developed a way to evaluate new treatments for some forms of attention deficit disorder. Working in mice, researchers at the School of Medicine showed that they can use brain scans to quickly test whether drugs increase levels of dopamine. The same group found that raising dopamine levels in mice alleviates attention deficits caused by neurofibromatosis type 1 (NF1), a condition that affects more than 100,000 people in the United States.
