CCN Colloquium: "Neurotransmitter Interactions in the Neural Bases of Therapeutic Treatments Against Drug Addiction"
The brain is an organ of communication. There is no single pathway for any neurobehavioral function or dysfunction. Drug abuse and addiction may at first appear to be due to the particular action of a drug at a neurotransmitter receptor or other physiological target process, but because of the intricate communication among neural systems, actions at a particular receptor quickly involves a much broader array of interacting systems.
