Aversion and Reward Brain Pathways Identified (AUDIO)
Caption
Neuorscientists used to think that a specific class of receptors in the brain was linked to aversion behaviors while other receptors and cells were activated to produce reward behaviors. But now, researchers at Washington University School Of Medicine in St. Louis have found that some of those receptors appear to go both ways, and that neurons only one millimeter apart have the capacity to activate either aversion behaviors or reward behaviors. They say the discovery could have implications for better understanding and more effectively treating addiction and depression. Jim Dryden has the story.
