For 10 points, name this primary neurotransmitter involved in the reward pathway, which is under-produced in Parkinson's disease.
The Nurr1 gene is important for the development of cells that primarily produce this molecule. Cabergoline and bromocriptine activate this molecule's receptors, while haloperidol is an inverse agonist to those receptors. This molecule is transported to the nucleus accumbens from the ventral tegmental area by the mesolimbic pathway. This molecule is produced by the hydroxylation then subsequent decarboxylation of (*) tyrosine. This catecholamine inhibits the secretion of prolactin, and it is primarily produced in a section of the basal ganglia known as the substantia nigra.
