Cocaine-linked genes enhance behavioral effects of addiction

Cocaine-linked genes enhance behavioral effects of…

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. The study, published by Cell Press in the May 14th issue of the journal Neuron, provides exciting insight into the molecular pathways regulated by cocaine and may lead to new strategies for battling drug addiction.  It is well established that addictive drugs induce persistent changes in the brain’s reward circuits. Previous research has indicated that addiction to drugs such as cocaine is associated with altered gene expression in the nucleus accumbens (NAc), a region of the brain that…

Chronic Cocaine Abuse: Abnormal Brain Structure

Researchers at the University of Cambridge have identified abnormal brain structures in the frontal lobe of cocaine users’ brains which are linked to their compulsive cocaine-using behaviour. Their findings were published today, 21 June, in the journal Brain. Led by Dr Karen Ersche, the Cambridge researchers scanned the brains of 120 people, half of whom had a dependence on cocaine. They found that the cocaine users had widespread loss of grey matter that was directly related to the duration of their cocaine abuse (i.e. the longer they had been using cocaine, the greater the loss of grey matter), and that this reduction in volume was…

Why Cocaine is So Addictive

Mount Sinai researchers have discovered how cocaine corrupts the brain and becomes addictive. These findings — the first to connect activation of specific neurons to alterations in cocaine reward — were published in Science on October 15. The results may help researchers in developing new ways of treating those addicted to the drug. Led by Mary Kay Lobo, PhD, Postdoctoral Fellow in the Department of Neuroscience at Mount Sinai School of Medicine and first author of the study, researchers found that the two main neurons (D1 and D2) in the nucleus accumbens region of the brain, an important part of the brain’s reward…

New research findings suggest that structural abnormalities in the brains of cocaine addicts are related in part to drug use and in part to a predisposition toward addiction
