Altered perception of reward in human cocaine addiction

ted ability to control behavior.

The ERP results showed a similarly graded brain response to monetary reward in healthy control subjects, but not in cocaine-addicted individuals.

"The dysfunctional interplay between reward processing and control of behavior observed in these studies could help to explain the chronically relapsing nature of drug addiction," Goldstein said. "Our results also suggest the need for new clinical interventions aimed at helping drug abusers manage these symptoms as part of an effective treatment strategy."
