| Comments | Although dopamine neurons are few (<1/100 000 brain neurons), they play an important role in regulating several aspects of basic brain function. They are necessary for the normal tasks of the regions they innervate, including motor behavior, motivation, and working memory. Dopamine neurons are also a central element in the brain reward system that controls the learning of many behaviors. |
