... , her baby's smile also lights up the reward centers of her brain, just like free money, ... imaging scanner. The machine measures blood flow in the brain. In the scans, areas of increased blood flow " ...
... dopamine levels were 50 percent lower and stimulated dopamine release was significantly attenuated in the brain reward systems of obesity-prone rats, compared with obesity-resistant rats. Defects in ...
... report connects molecular genetics with earlier studies of choice and preference and with investigations of the brain's reward circuitry. The researchers focused on a gene called CREB1 that has been ...
... involves both structural and functional changes in brain nerve cells that are still poorly understood ... seems that diazepam causes a similar change in the brain's reward-inducing dopamine cells as a dose ...
... over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood. However, a single drug or alcohol dose is ...
... get older, it may stem from aging-related changes in a brain reward circuit. Compared to young participants, older participants showed less activity in brain motivation hubs while they viewed a slot ...
... into how both natural and artificial rewards interact with each other, and specifically how damage to brain reward systems during addiction can disrupt processing of natural rewards such as social ...
A common treatment for attention deficit/hyperactivity disorder, prescribed millions of times a year, may change the brain in the same ways that cocaine does, a new study in mice suggests.
... shows that childhood adversity is associated with diminished neural activity in certain regions of the brain.Harvard researchers used functional magnetic resonance imaging (fMRI) to monitor brain ...
... those elicited by drugs of abuse such as cocaine and nicotine, pointing to a general involvement of the brain's "reward" system. A common factor may be activation of orexin neurons in the brain, which ...
Exposing rats to a context associated with eating chocolate activates a part of the brain's reward system known as the orexin system. The results have implications for the development of new drug ...
... "Furthermore, these results reveal neural substrates underlying alcoholism-related emotional anomalies and impairments of brain reward circuitry that mediate addictions such as alcoholism," she added.
... this year we found that the adenosine A2A receptor interacts with the mGlu5 glutamate receptor found in the brain’s reward pathway to regulate drug-seeking. “Consequently, a drug developed to target ...
... is known to have an effect on food intake by increasing feelings of hunger and the urge to eat. New findings show that the ghrelin system may also be involved in addictive behaviors and brain reward.
