Dopamine is a neurotransmitter, which is a chemical messenger that carries signals between brain cells (neurons). It plays a crucial role in various bodily functions and processes, such as regulating movement, emotions, motivation, and the brain's reward and pleasure centers. Dopamine is associated with feelings of pleasure and reward, as well as motivation and reinforcement of certain behaviors. Imbalances or dysfunctions in dopamine levels or its receptors have been linked to several neurological and psychiatric disorders, including Parkinson's disease, addiction, schizophrenia, and depression.
