Definition

Dopamine (dopaminergic) system plays an important role in central neural system, taking part in regulating motor control, executive functions, motivation, reinforcement, reward, sleep, feeding, attention, cognitive functions, olfaction, vision, hormonal regulation, and outside of central neural system in sympathetic regulation and penile erection.
