amatic in the DS during reward anticipation. This shows that not only is reward expectancy processed differently in an adolescent brain, but also it can affect brain regions directly responsible for decision-making and action selection.

"Adolescence is a time when the symptoms of most mental illnessessuch as schizophrenia and bipolar and eating disordersare first manifested, so we believe that this is a critical period for preventing these illnesses," Moghaddam said. "A better understanding of how adolescent brain processes reward and decision-making is critical for understanding the basis of these vulnerabilities and designing prevention strategies."

The Pitt team will continue to compare adolescent and adult behavior, especially as it relates to stimulantssuch as amphetaminesand their influence on brain activity.
