Direct projection of catecholamine (presumably dopamine)-containing neurons from hypothalamus to spinal cord.
A procedure for combining catecholamine (CA) and horseradish peroxidase (HRP) histochemistry was used to demonstrate that some of the catecholamine-containing cells in the rabbit dorsal hypothalamus project directly to the thoracic spinal cord. These cells, which are probably dopaminergic, may be involved in the integration of pituitary hormonal secretion and peripheral autonomic nervous regulation.
