Brain Stimulation Reward
In 1953, Olds and Milner discovered that rats would readily learn to work for electrical stimulation of certain brain sites. Their findings inspired a large body of research on the neural basis of reward, motivation, and learning. Unlike consummatory behaviors, which satiate as a result of ingestion of and contact with the goal object, performance for rewarding brain stimulation is remarkably s...
متن کاملCocaine enhances resistance to extinction of responding for brain-stimulation reward in adult prenatally stressed rats.
The present experiment assessed whether prenatal stress (PS) can alter the ability of acute and chronic cocaine administration to increase and decrease the rewarding effectiveness of the medial forebrain bundle (MFB) using intracranial self-stimulation (ICSS), and also whether PS can affect the extinction of the MFB stimulation response. Adult male offspring of female rats that received PS or n...
متن کاملDopamine D3 receptor antagonism inhibits cocaine-seeking and cocaine-enhanced brain reward in rats.
dopamine D3 receptor is preferentially localized to the mesocorticolimbic dopaminergic system and has been hypothesized to play a role in cocaine addiction. To study the involvement of the D3 receptor in brain mechanisms and behaviors commonly assumed to be involved in the addicting properties of cocaine, the potent and selective D3 receptor antagonist trans-N-[4-[2-(6-cyano-1,2,3,4-tetrahydroi...
متن کاملJuvenile Traumatic Brain Injury Increases Alcohol Consumption and Reward in Female Mice.
Traumatic brain injury (TBI) is closely and bi-directionally linked with alcohol use, as by some estimates intoxication is the direct or indirect cause of one-third to one-half of all TBI cases. Alcohol use following injury can reduce the efficacy of rehabilitation and increase the chances for additional injury. Finally, TBI itself may be a risk factor for the development of alcohol use disorde...
متن کاملRepeated electrical stimulation of reward-related brain regions affects cocaine but not "natural" reinforcement.
Drug addiction is associated with long-lasting neuronal adaptations including alterations in dopamine and glutamate receptors in the brain reward system. Treatment strategies for cocaine addiction and especially the prevention of craving and relapse are limited, and their effectiveness is still questionable. We hypothesized that repeated stimulation of the brain reward system can induce localiz...
