Abstract

Dopamine is primarily produced in the substantia nigra (SN) and the ventral tegmentum area (VTA) in the brain. It plays a well-established role in the motor control, reward, mood regulation and addiction behaviour. Dopamine release has been shown to be regulated by the circadian clock and hence, plays a regulatory role in the sleep-wake cycle. Clinically, dopaminergic agents have been widely used to modulate alertness. The following review offers a demonstration of the heterogeneous dopamine system in the brain and the various studies investigating the circadian rhythmicity of the dopamine system and its regulation of sleep-wake behaviour. Additionally, it suggests a potential link between the circadian clock and the sleep-wake cycle in mood regulation through the dopaminergic system.
