Body's own substance that is attached to adrenergen nerve endings acts as a carrier substance. Dopamine is a neurotransmitter that occurs primarily in the CNS or midbrain and can respond to neurons called "dopaminerg". From the midbrain, important dopaminergic systems (structures that work with dopamine as a neurotransmitter) ascend into the cerebrum and the diencephalon.

But dopamine is also a neurotransmitter in some systems of the vegetative nervous system and regulates the blood circulation of internal organs. It is required for a multitude of vital control and regulation processes. It acts as a stimulator for the sympathetic sympathetic nervous system, but in low concentrations it increases the blood flow to the abdominal and renal vessels so that renal perfusion is increased. c

Dopamine is also produced in the hypothalamus and released as a neurohormone. As such, it inhibits the release of prolactin from the adenohypohysis.

Dopamine influences the extrapyramidal motor system - this may be related to Parkinson's disease. The dopamine balance is also related to the neurobiological aspects of psychoses and various disorders.

Dopamine is also associated with the psychiatric disease of schizophrenia. It also regulates the blood flow to the abdominal organs, in particular dopamine is involved in the control of the kidneys.
