New clues to brain dopamine control, cocaine addiction

Article Abstract:

Experiments by Marc Caron and colleagues on mice with the gene for the dopamine transporter protein disabled demonstrate the importance of the transporter in controlling dopamine levels and in drug addiction. The results may help the development of new drugs for addiction and Parkinson's disease.
