A gene required for addictive behavior

Cocaine can have a devastating effect on people. It directly stimulates the brain’s reward center, and, more importantly, induces long-term changes to the reward circuitry that are responsible for addictive behaviors. Alban de Kerchove d’Exaerde from the Universit√© Libre de Bruxelles, Belgium, and his colleagues have now uncovered that a gene called Maged1 plays a crucial role in controlling these pathological changes. This finding was published today in EMBO Reports.
