In the beginning, Dopamine was perceived as the "pleasure molecule".

Most dopamine neurons signal a reward prediction error; they are activated by more reward than predicted (positive prediction error), remain at baseline activity for fully expected rewards, and show depressed activity with less reward than predicted (negative prediction).
