The most important reward pathway in brain is the mesolimbic dopamine system. This circuit (VTA-NAc) is a key detector of a rewarding stimulus.
These regions are connected by what is called the pleasure or reward bundle. In neuroanatomical terms, this bundle is part of the medial forebrain bundle (MFB) , whose activation leads to the repetition of the gratifying action to strengthen the associated pathways in the brain.
