title: Spinal peptidergic and catecholaminergic systems and nociception.
abstract: The authors review recent findings about the electrophysiology and anatomy of spinal peptidergic systems. The role of spinal catecholaminergic systems in nociception is also discussed. Recent data about the action of norepinephrine on dorsal horn neurons are presented.
