What Is the Function of Dopamine?

Dopamine is a neurotransmitter produced by the hypothalamus and has many natural functions. It can also be synthesized and taken as a medication to treat specific conditions, especially neurological disorders.

  1. Prolactin

    • The release of dopamine inhibits the release of prolactin by the anterior pituitary lobe of the hypothalamus. This hormone is primarily responsible for causing lactation.

    Precursor

    • Dopamine is needed to produce epinephrine and norepinephrine. These compounds are hormones that serve a variety of functions, such as the "fight or flight" response.

    Pleasure

    • Dopamine causes feelings of pleasure and is released by rewarding experiences such as food and sex. This function of dopamine is essential in causing survival-oriented behavior.

    Cognitive Functions

    • Proper dopamine levels are required to maintain good cognitive functions such as concentration, memory and problem-solving. This function makes dopamine useful in treating attention deficit disorder.

    Parkinson's Disease

    • The symptoms of Parkinson's disease can be relieved by increasing the level of dopamine in these patients. Dopamine used for this purpose must be administered in the form of L-DOPA in order to cross the blood-brain barrier.
