Cocaine: Perceived as a reward by the brain?
Cocaine is one of the oldest drugs known to humans, and its abuse has become widespread since the end of the 19th century. view more (2009-05-20)
Cocaine-linked genes enhance behavioral effects of addiction
New research sheds light on how cocaine regulates gene expression in a crucial reward region of the brain to elicit long-lasting changes in behavior. view more (2009-05-14)
Computer Model Shows Changes in Brain Mechanisms for Cocaine Addicts
About 2 million Americans currently use cocaine for its temporary side-effects of euphoria, which have contributed to making it one of the most dangerous and addictive drugs in the country. view more (2009-09-23)
Animal research suggests new strategy for treating cocaine addiction
New research in monkeys suggests the feasibility of treating cocaine addiction with a "replacement" drug that mimics the effects of cocaine but has less potential for abuse - similar to the way nicotine and heroin addictions are treated. view more (2008-04-07)
UCI researchers find new way to fight cocaine addiction
UC Irvine pharmacological researchers have discovered that blocking a hormone related to hunger regulation can limit cocaine cravings. view more (2009-04-02)
Research reveals molecular fingerprint of cocaine addiction
The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function. view more (2008-05-28)
Delving deeper into the machinery of cocaine addiction
Researchers are now understanding in greater detail the molecular machinery underlying the short-term brain changes that produce the high of cocaine, as well as the longer-term changes behind addiction. Their findings offer hope for targeted drugs that can short-circuit that addiction machinery. view more (2005-10-20)
New study finds common herbal supplement helps to reduce cocaine cravings
A new study funded by the National Institutes of Health (NIH) suggests that a common over-the-counter herbal supplement can reduce the cravings associated with chronic cocaine use. view more (2005-12-14)
Gene therapy reduces cocaine use in rats
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have shown that increasing the brain level of receptors for dopamine, a pleasure-related chemical, can reduce use of cocaine by 75 percent in rats trained to self-administer it. view more (2008-04-16)
Cocaine-induced synaptic plasticity linked to persistent addictive behaviors
The persistent nature of addiction is its most devastating feature. Understanding the mechanism underlying this phenomenon is the key for designing efficient therapy. Two separate studies published by Cell Press is the August 14 issue of the journal Neuron identify specific cocaine-induced changes in dopamine (DA) neurons that play a pivotal role... view more...

Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent. view more (2008-02-19)
Vaccines help kick drug habits
A pair of new vaccines designed to combat cocaine and methamphetamine dependencies not only relieve addiction but also minimize withdrawal symptoms. view more (2007-06-25)
UCI neurobiologists find treatment to block memory-related drug cravings
A novel chemical compound that blocks memory-related drug cravings has the potential to be the basis of new therapies to aid drug-addiction recovery efforts, UC Irvine neurobiologists have found. view more (2005-09-19)
Honeybees succumb to cocaine's allure
Since its discovery in the 18th century, cocaine has been a scourge of western society. Strongly stimulating human reward centres in low doses, cocaine is extremely addictive and can be fatal in high doses. view more (2008-12-23)
UT Southwestern researchers find alterations in brain's circuitry caused by cocaine
Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction. view more (2005-10-24)
Comparison of cocaine and methamphetamine 'highs' finds differences in onset, pattern and duration
Investigators at the Jane and Terry Semel Institute for Neuroscience and Human Behavior at UCLA examining responses to cocaine and methamphetamine use find distinct differences in onset, pattern and duration. view more (2005-08-25)
Recreational cocaine use may impair inhibitory control
The recreational use of cocaine has rapidly increased in many European countries over the past few years. view more (2007-11-07)
Cocaine: How addiction develops
Permanent drug seeking and relapse after renewed drug administration are typical behavioral patterns of addiction. Molecular changes at the connection points in the brain's reward center are directly responsible for this. view more (2008-08-22)
Halting retrieval of drug-associated memories may prevent addiction relapse
Disrupting the brain's retrieval of drug-associated memories may prevent relapse in drug addiction, according to new research in the August 13 issue of The Journal of Neuroscience. view more (2008-08-13)
High resolution 'snapshots' detail dynamics of a cocaine antibody
Cocaine-binding antibodies have shown some promise in their ability to neutralize cocaine toxicity, but their binding ability is severely impaired by high concentrations of the drug. view more (2006-02-09)
