Dopamine: one of the catecholamine neurotransmitters in the brain; it is derived from tyrosine and is the precursor to norepinephrine and epinephrine; dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement; dopamine receptors mediate its action.Source: CRISP.t is derived from tyrosine and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action. Source: MeSH 2007.
Dopamine production. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area. It is a neurohormone that is released by the hypothalamus.opamine is also used as medication. It acts on the sympathetic nervous system. Application of dopamine leads to increased heart rate and blood pressure. Dopamine cannot cross the blood-brain barrier, so dopamine given as a drug does not directly affect the central nervous system.
