The most important reward pathway in brain is the mesolimbic dopamine system. This circuit (VTA-NAc) is a key detector of a rewarding stimulus.
Dopamine receptors in the area of the nucleus accumbens are part of the brain's reward system. Dopamine motivates us toward pleasure. It is associated with the anticipation of something the brain has identified as valuable, rewarding, and special to us. That something can be anything, including a person or a drug.
