March 2008 Summarizes research on the effects of long-term regular cocaine abuse on the cardiovascular system in African Americans.
Describes a study showing that cocaine, which increases dopamine levels, also can tap into an intracellular dopamine reserve pool.
Reports on the work of addiction researchers who are learning how acute and chronic cocaine exposure regulates certain genes, based on knowledge from developmental and cancer biology.
Discusses the central importance of studying drugs' effects on neurotransmission and describes some of the most common experimental methods used in this research.
October 2007 Reports on two studies indicating that orexin, a neuropeptide that stimulates eating and regulates wakefulness, also fosters animals' drug seeking and craving responses to drugs.
April 2007 Describes investigations to advance the development of potential drug abuse relapse prevention agents by targeting specific receptors of the neurochemical serotonin.

February 2007 Discusses the work of NIDA’s Division of Basic Neuroscience and Behavioral Research, the Institute’s locus for studies into the fundamental brain mechanisms underlying drug abuse and addiction.
February 2007 Describes evidence supporting the view that developmental differences in brain systems that use the neurotransmitter dopamine underlie age differences in susceptibility to drug abuse.
