Carboni, … DiChiara et al. J Neurosci 20:RC102(1-5), 2000 What do we know about addictive drugs from animal studies? “… cocaine, morphine, nicotine, and ethanol share the property of increasing DA transmission in the BNST. This effect may be related to an action at the level of neuronal circuits activated by natural reinforcers … suggest[ing] that DA transmission of the BNST plays a role in the mechanism of drug abuse and addiction.”

aaarrrggghhhh!!!!! – show me BP

what phenomenon is this?

does everyone understand what they are showing here? euphoria BP Individual subjects (need to have all brains in same space) plot R value at given voxel
