Drug addiction is a chronic relapsing brain disorder characterized by a compulsion to take a drug with loss of control over drug intake. The hypothesis under discussion here is that chronic drug use produces long-lasting dysfunctions in neurons associated with the brain reward circuitry, and this ...

Several studies demonstrate that anandamide exerts an overall modulatory effect on the brain reward circuitry. Several reports suggest its involvement in the addiction-producing actions of other abused drugs, and it can also act as a behavioral reinforcer in animal models of drug abuse. Importantly,...
Addiction comes about through the brain’s normal pathways of pleasure. It is known that addiction changes the circuitry of the brain in ways that make it increasingly difficult for people to regulate the allure of an intense chemical rush of reward. In response to repeated use of a highly ...
The researchers have used their innovations to glean important insights into the mechanisms of DBS and addiction in apreclinical study. The experimental DBS treatment cut the flow of dopamine to thenucleus accumbens, the brain's reward center, by nearly half. ...
3Because a lot of those drugs of abuse are dopamine, it becomes this cyclical loop where there's no other behavior that can evoke the same level of release. Right, in fact, I sort of define addiction as a progressive narrowing of the things that bring you pleasure. And I say that beca...
"This simple experiment models a learning phenomenon that occurs in lots of differentbrain regions," Stuber said. "It is critical for motivation and decision making, and of course it can go awry in drug and food addiction, depression, and other neuropsychiatric disorders." ...
Addiction research has become increasingly focused on how addictive drugs affect neural signaling within the brain's reward circuitry. New work shows that the frustration of not receiving drugs when they are expected can also affect the inner workings of reward circuits....
