Summary:
Dopamine, a chemical messenger believed for more than two decades to be the end point of the brain's pleasure system, appears not to be that molecular reward after all, a new study shows. The University of North Carolina at Chapel Hill study suggests instead that dopamine plays an early central role in pleasure, but another chemical -- possibly serotonin -- actually rings the chimes for humans and animals alike.
