using control animals and rats with 6-hydroxydopamine-induced lesions of spinal ca axons , it was concluded that up to 93 % of all noradrenergic ( ne ) neurons present in the area investigated send an axonal process to the thoracic spinal cord and that ne neurons constitute at least 90 % of all spinally-projecting neurons present in the same area .
