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.
October 2007 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.
April 2007 Reports on data that reviewing the benefits of addiction treatment among abstinent men as compared with those who continued to abuse cocaine.
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 Summarizes an animal study of the neural changes in the amygdala portion of the brain that occur as a result of cocaine exposure followed by withdrawal of the drug.
February 2007 Reports on the work of researchers who used brain images to correlate cocaine-addicted patients' regional brain responses to drug cues with their outcomes in subsequent treatment.
February 2007 Reports on a study that documenting changing emotional and neurobiological responses to cocaine with successive doses during a single session of drug taking.
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.
