For 10 points, name this inhibitory neurotransmitter implicated in arousal and addiction and supposedly central to pleasure and reward.
Phenothiazines such as chlorpromazine work by blocking receptors for this molecule, which is transported to its primary location in the tuberoinfundibular pathway. Monoamine oxidase and catechol-o-methyl transferase break down this chemical, a process enhanced by the drug reserpine. A catecholamine produced in the substantia nigra and released from the hypothalamus, this compound inhibits the release of prolactin in the pituitary gland, among other functions. Derived from tyrosine and a precursor to adrenaline, disorders that result from a deficiency in this molecule include ADHD and Parkinson's disease.
