Sprouting of dopaminergic axons

The behavioral and functional consequences of dopamine receptor activation have been extensively examined and reported and some of these studies have already been discussed above. However the regulation of the size of the terminal arbor of dopamine neurons is mediated by dopamine receptors. This phenomenon has recently been reported (Finkelstein, 2002) and has significant ramifications for the behavioral effects mediated by dopamine and also in the interpretation of studies examining dopamine neurotransmission. The following section is a discussion and review of the role of dopamine receptors on the regulation of sprouting of dopaminergic neurons and axons. [Pg.171]
