[The spinal dopaminergic system].
A new dopaminergic innervation has been described quite recently: the dopaminergic spinal cord system. In this review are presented the different steps which lead to the individualization of this dopaminergic system and the reported results actually available concerning its probable anatomical organization. Finally, most of the data which illustrate the possible functions of this system are discussed. Interestingly, its participation in the transmission of nociceptive signals and the control of cardiovascular patterns appear now well established. Such functional implications give new information on the possible targets of central dopaminergic agonists and antagonists, particularly at the cardiovascular level.
