Dopamine is a neurotransmitter that serves as a chemical messenger in the nervous system and permits individual nerve fibers (neurons) to communicate with each other. It belongs to the class of compounds known as monoamines, and more specifically to a subclass of chemicals called catecholamines. Dopamine can act either as an inhibitory mechanism or an excitatory mechanism in the nervous system, depending on the location of dopamine neurons, and the receiving characteristics of the next neuron in the chain. Dopamine is biosynthesized in the body (mainly by nervous tissue and the medulla of the adrenal glands) first by the hydroxylation of the amino acid L-tyrosine to L-DOPA via the enzyme tyrosine 3-monooxygenase, also known as tyrosine hydroxylase, and then by the decarboxylation of L-DOPA by aromatic L-amino acid decarboxylase. Dopamine is a brain chemical which produces feelings of satisfaction and pleasure. It is heavily secreted while falling in love and commonly found during the attraction phase of a relationship. It has many functions in the brain, including important roles in behavior and cognition, voluntary movement, motivation, punishment and reward, inhibition of prolactin production (involved in lactation and sexual gratification), sleep, mood, and attention, working memory, and learning. Dopaminergic neurons (i.e., neurons whose primary neurotransmitter is dopamine) are present chiefly in the ventral tegmental area (VTA) of the midbrain, the substantia nigra pars compacta, and the arcuate nucleus of the hypothalamus.
