The most important reward pathway in brain is the mesolimbic dopamine system. This circuit (VTA-NAc) is a key detector of a rewarding stimulus.
The point of the reward circuitry is to positively reinforce actions that promote the survival of the species. During what the brain perceives to be as beneficial actions, dopamineâs release makes our brains âhappy,â thus encouraging us to do it again. Though âextreme actionsâ inherently donât promote survival, and in fact endanger it, the rush to preserve life causes the release of dopamine and consequently pleasure.
