Résumé :
The National Institute on Drug Abuse (NIDA) is marking its 30th year of research in substance abuse. Over this period, significant advances have given us a better understanding of the neurobiology of drug addiction and of its treatment. To start with, scientific findings documenting long-lasting changes in the brain of individuals addicted to drugs have led to the conceptualization of drug addiction as a disease of the brain. Moreover, through the use of animal models and through imaging studies in human subjects, it has become possible to delineate neurotransmitter systems and neuronal circuits that are disrupted by the use of drugs. Ten studies in this issue exemplify some of these advances. This editorial discusses these papers within the framework of NIDA's top research priorities: prevention, treatment, and HIV/AIDS.
