Keep in mind that every "Dopamine does ____" is an extreme simplification. Dopamine is a neurotransmitter that is used by a number of different neurons throughout the brain, as well as in different roles in the body outside of the brain.

This article, like every study of dopaminergic neurons, is about specific neurons that happen to use dopamine for some of their signaling. It's incorrect to extrapolate this to generalizations about what dopamine does or does not do, because it depends on the specific neurons.
