title: Spinocervical tract cells in cat and dog, labeled by the retrograde transport of horseradish peroxidase.
abstract: The location of cells of origin of the spinocervical tract has been determined in cat and dog by injecting horseradish peroxidase into the lateral cervical nucleus (LCN). Retrogradely labeled cells were found predominantly in the ipsilateral nucleus proprius of the dorsal horn along the entire spinal cord. Cells of Clarke's column and contralateral ventral horn cells were not labeled, in agreement with previous electrophysiological indications that the spinocerebellar tracts do not maintain collateral terminations in the LCN.
