Like many other neurotransmitters, Dopamine is associated with many functions, some of them critical to the normal functioning of the brain and hence the human body.
Dopamine plays an important role in human behavior, cognition, attention, movement, learning and is especially associated with the response of human brain to motivation and reward. It has a huge number of other functions too like stopping the prolactin production, a chemical which is responsible for lactation.
