Adrenaline neurons in the rostral ventrolateral medulla innervate thoracic spinal cord: a combined immunocytochemical and retrograde transport demonstration.
Adrenaline-containing neurons in the C1 group of the ventrolateral rostral medullary reticular formation which project to the thoracic spinal cord were identified by a combined retrograde transport immunocytochemical technique. No other medullary catecholamine neurons, including the A1 and A2 noradrenaline cells, project to thoracic spinal cord. These data, taken with results of other studies of spinal catecholamine innervation, suggest a segmental segregation of projections to spinal cord by dopaminergic, noradrenergic, and adrenergic neurons.
