Decreased striatal dopaminergic responsiveness in detoxified cocaine-dependent subjects
Cocaine blocks the reuptake of dopamine, a neurotransmitter involved in the control of movement, cognition, motivation and reward. This leads to an increase in extracellular dopamine; the reinforcing… Expand

123I-labeled AM251: a radioiodinated ligand which binds in vivo to mouse brain cannabinoid CB1 receptors.
We have investigated the binding of 123I-labeled N-(piperidin-1-yl)-5-(4-iodophenyl)-1-(2,4-dichlorophenyl)-4-methy l-1 H-pyrazole-3-carboxamide (AM251), an analog of the cannabinoid receptor… Expand
