Intrathecal injections of norepinephrine (0.30 μmol) and clonidine (0.035 μmol) produced decreases in neural activity recorded from the lumbar sympathetic chain and caused changes in rat thermoregulation consistent with a reduction in efferent sympathetic activity. These results support the conclusion that bulbospinal noradrenergic pathways inhibit sympathetic outflow. The data also indicate that the spinal cord is a potential site of action for clonidine.
