A neuroimaging study reports dopamine activity does not reflect the number of dopamine neurons in the substantia nigra of people with Parkinson's disease.
Researchers report on a link between the dopamine system and initiating joint attention in children at high risk for autism.
A new study reports high fat diets can impair the function of the mesolimbic dopamine system.
Researchers have identified a significant role dopamine plays in the development of heroin addiction. The study reports dopamine appears to directly cause drug reinforcement and, when dopamine neurons are silenced, mice are less likely to self administer the drug.
A new study reveals the role dopamine plays in controlling eating behaviors. Researchers found when people crave specific foods, the brain releases more dopamine when they finally consume the item. The study reports the gastrointestinal tract is in constant contact with the brain and uses reward stimuli to control our desire for food.
Using mouse models, researchers found bile diversion surgery reduced cocaine induced increases in dopamine release and cocaine related behaviors. Researchers believe bariatric surgery or the consumption of a synthetic bile drug may help curb cocaine addiction in humans.
