Dopamine

=__Dopamine__= Dopamine is a main neurotransmitter found in the brain. It is made up of five different dopamine receptors: D1, D2, D3, D4, and D5. Dopamine can occur in different parts of the brain and is also a neuro hormone. Dopamine's main behaviors include movement, pleasure, cognition, and motivation. As a neurohormone its main function is to release prolactin from the anterior lobe of the pituitary. Dopmaine is classified as a catecholamine and is formed by the decarboxylation of dopa. Dopa is what is mainly used to treat Parkinsons Disease.

When Dopamine is released it produces feelings of satisfaction, such as when eating food. This is why when over repeated times people repeat tasks which require the release of Dopamine, such as eating even when their bodies aren't really hungry. This idea is the same as with someone who is addicted to cocaine, but in a much more severe way.
