Dr. Britt has characterized some of the ways that the nucleus accumbens integrates dopamine dependent reinforcement signals with environmental stimuli, which depend on a second neurochemical called glutamate. Glutamate-dependent signals to the nucleus accumbens come from many other brain regions, such as ...
It is argued that, when pushed by fate and circumstance into a physiological brain state of anti-reward, human behavior changes and mental health is affected, depending on individual vulnerabilities. A unified conceptual account that places dopamine function at the centre of...

After the advances they have made in understanding rewards, the researchers are now exploring how the brain responds to punishment. Dayan says the smart money is on another brain signalling chemical,serotonin. “That may be involved in punishment, but it’s fairly speculative at the moment.” ...
We note that a pleasant stimulus is often called a rewarding stimulus or simply a reward. However, it is useful to keep in mind that actual reward lies in active processes of the brain and mind that reacts to a stimulus rather than the stimulus itself. Further, reward may appear at first...
Columbia University’s Zuckerman Mind Brain Behavior Institute, the Champalimaud Centre for the Unknown, and Seattle Children’s Research Institute sheds new light on this mystery. It reveals how dopamine not only signals a reward but also guides animals to home in on the specific behaviors that ...
