Abstract
The organization of sources providing catecholaminergic innervation of the upper thoracic spinal cord was investigated in rats using a sensitive technique specific to tracing connections between catecholaminergic neurons. Large numbers of pontine catecholaminergic neurons belonging to groups A5, A6, and A7 and some single cells from medullary group A1 send out direct projections to the spinal cord. It is postulated that pontine catecholaminergic neurons contributing to innervation of the spinal cord and the medulla are noradrenaline-containing and adrenaline-containing respectively.
