Latest Cocaine and amphetamine regulated transcript Stories
New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction.
Research published by Cell Press in the January 12 issue of the journal Neuron provides fascinating insight into a newly discovered brain mechanism that limits the rewarding impact of cocaine.
New research findings to be presented at the upcoming annual meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that ghrelin, a natural gut hormone that stimulates feeding, also modulates the ability of tasty food and food-related cues to alter dopamine levels within the striatum, a critical component of the brainâ€™s reward system.
U.S. researchers have found cocaine regulated molecular pathways that may lead to addiction treatments. The study, published in Cell Press, finds long-lasting changes in behavior are elicited as cocaine regulates gene expression in a crucial reward region of the brain.
Initial drug use can be motivated by curiosity or peer pressure, but in some animals it can result from a stressful event, researchers in Puerto Rico said. Natasha Lugo-Escobar, Nicole Carreras and Annabell C.
